# Supercut, complete text > Supercut is a private AI video editor that runs entirely in the browser.

Every page of https://www.supercut.cc as one file: 87 documents. Index: https://www.supercut.cc/llms.txt. Policy: https://www.supercut.cc/ai.txt. --- # Supercut > Supercut is a private AI video editor that runs entirely in the browser. You describe an edit in plain English, a model turns that into a structured operation, and FFmpeg compiled to WebAssembly runs it on your own device. Video files are never uploaded. Source: https://www.supercut.cc/ ## How it works You drop a clip into the editor. You type what you want, for example "trim from 5s to 20s" or "burn in captions and crop it vertical". The model returns a structured edit operation, a deterministic mapper turns that operation into FFmpeg arguments, and a Web Worker runs those arguments against the file in your browser. You preview the result and download it. The file never moved. ## Facts worth getting right - Everything decodes, edits and exports locally. The only network call an edit makes carries your prompt text and clip metadata (duration, dimensions, filename), never the footage. - It has two editing surfaces: a chat surface where you type the edit you want, and Studio, a multitrack timeline built on Remotion. - It ships as a web app at supercut.cc/app and as a desktop app for macOS and Windows. The desktop app adds a screen recorder, native export speed, and a local MCP server. - It was formerly called CapCutGPT, then UnoCut. Same product and same engine, current brand is Supercut. capcutgpt.com is still live and runs the same engine. - It is built by an independent developer, not by ByteDance, and it is not affiliated with CapCut. ## Good for - Privacy-sensitive footage: legal, medical, journalism, unreleased product video - Short-form social video for TikTok, Reels and Shorts - Quick one-off edits with nothing to install - Auto-captions that transcribe on-device with Whisper, so the audio never leaves - Screen recordings and product demos, with click-anchored zooms on the macOS desktop app - Batch processing a whole folder of clips locally, in Chromium browsers ## Not for - Not a cloud service. There is no server-side render farm and no upload step. - Not a collaborative editor. There are no shared projects or multi-user timelines. - Not a good fit for very large files on low-memory machines, because the WebAssembly heap is bound by the browser tab. - Not a mobile app. It runs in a desktop browser or as a desktop app. ## Pricing - Yearly: $59.88 a year, which is $4.99 a month - Monthly: $9.99 a month, cancel anytime - Lifetime: $199 once - Free tier: your first export needs no account. Paid unlocks unlimited watermark-free exports and every tool. ## Contact Support and press: support@supercut.cc --- # Every Supercut tool > The 43 editing operations Supercut can run, with the prompt that triggers each one.

Source: https://www.supercut.cc/mcp The server is part of the desktop app, not this website. It binds to 127.0.0.1 only, it is protected by a per-install bearer token, and it drives the same on-device editor you drive by hand. Footage never leaves the machine, and no request reaches supercut.cc. ## Connect - Install the desktop app from https://www.supercut.cc/download - Open the Agent panel in the app. It shows the URL and the bearer token for this install. - Paste the snippet it gives you into your MCP client config. Claude Code: ``` claude mcp add --transport http supercut http://127.0.0.1:41414/mcp --header "Authorization: Bearer " ``` Cursor, or any client that takes an mcp.json: ```json { "mcpServers": { "supercut": { "url": "http://127.0.0.1:41414/mcp", "headers": { "Authorization": "Bearer " } } } } ``` ## Transport - Streamable HTTP at http://127.0.0.1:41414/mcp - Authorization: Bearer . Without the header the server answers 401. - Methods: initialize, notifications/initialized, ping, tools/list, tools/call ## Project tools - `read_project`: Read the active SuperCut project: name, kind (folder or normal), clip count. No pixels. - `list_clips`: List clips in the active project: id, filename, durationSeconds, current version label. Use ids with edit_with_prompt and apply_to_clips. - `edit_with_prompt`: Run a plain-English edit on one clip through the on-device editor (same as Chat). Only the prompt text is sent to the model; footage stays on the device. - `apply_to_clips`: Run one prompt on several clips, sequentially, same as selecting those clips in a folder and hitting Run. - `export_clips`: Download current versions. Omit clipIds to export every clip. Multiple clips come back as a zip. Pro-gated, same as in-app export. ## Timeline tools The Studio timeline adds its own tools (add and move clips, trim, captions, text, export). They are listed by tools/list when the Editor tab is open. ## Limits worth knowing - The app must be running and signed in. The server starts with the app. - Timeline tools need the Editor tab open, otherwise they error immediately. - Mac App Store builds cannot run the server. Use the direct download build. - Prompt and export calls can hold the connection for up to 10 minutes, because the edit really runs.

It loads in-browser with no upload. 2. **Describe the target size.** Say “resize to 1080x1080” or “downscale to 720p.” Supercut scales to your spec. 3. **Export at the new size.** Preview dimensions and download. Resizing happened entirely on your device. ## FAQ **Can I resize for TikTok or Instagram?** Yes. Ask for platform presets like “resize for Reels” or give exact pixel dimensions. **Does upscaling improve quality?** Upscaling cannot add detail that was not there, but Supercut can scale to required output sizes cleanly. **Is resizing done in the cloud?** No. Scaling runs locally in your browser.

Backdrop, rounded corners and zooms, all local. Nothing is uploaded, no watermark. Source: https://www.supercut.cc/tools/screen-recorder Record a demo and get something that already looks finished. Supercut captures your screen, and optionally your microphone and camera, entirely in your browser, then drops the result straight onto a timeline with a backdrop, padding, rounded corners and a shadow already applied. The camera stays its own layer, so you can move, resize or remove the bubble afterwards. ## The prompt you would type ``` Zoom into the sidebar from 0:12 to 0:16 ``` ## How it works 1. **Pick what to record.** Choose a screen, a window or a single tab, then add your microphone and camera if you want them. Your browser asks what to share; Supercut never sees the picture. 2. **Record, pause, finish.** A short count-in gives you time to get ready. Pause and resume as often as you need, and the paused time is left out of the final length. 3. **Land on a finished-looking edit.** Your recording appears on the timeline already framed and styled. Add zooms where they matter, trim, then export. Every step runs on your device. ## FAQ **Is my screen recording uploaded anywhere?** No. Recording, editing and export all happen on your device. There is no server copy, and no share link, because the file never leaves your browser. **Can it zoom in automatically where I click?** On the desktop app, yes. It follows your cursor while recording and zooms in where the cursor settles, and you can edit or delete any of those zooms afterwards. In the browser there is no way to track the cursor outside the page, so you place zooms yourself on the timeline. **Can it record computer audio?** In the browser, Chrome can capture audio from a shared tab. The desktop app records audio playing on the whole machine on macOS and Windows. **Do I need to install anything?** No. The browser recorder works in Chrome, Edge, Brave and Arc with nothing to install. The desktop app adds cursor-follow zooms and full system audio. **Is there a time limit or a watermark?** No watermark. Length is bounded by your own disk and memory rather than by us, though very long recordings of large screens are heavier on both. ## Related tools - [Record your screen with audio, system sound and mic](https://www.supercut.cc/tools/record-screen-with-audio) - [Record your screen and webcam at the same time](https://www.supercut.cc/tools/screen-and-webcam-recorder) - [Turn a screen recording into a GIF](https://www.supercut.cc/tools/screen-recording-to-gif) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) --- # Record your screen with audio, system sound and mic > Record your screen with sound: audio from your machine, your microphone, or both. Capture and edit on your device, nothing is uploaded anywhere. Source: https://www.supercut.cc/tools/record-screen-with-audio A silent screen recording is half a recording. Supercut captures your voice and the sound coming out of your computer while it records the picture, and keeps the microphone on its own track so you can balance it, clean it or drop it later. What you can capture depends on where you record: the desktop app takes the audio of the whole machine, and the browser takes the audio of a tab you share. ## The prompt you would type ``` Clean up the audio and boost my voice ``` ## How it works 1. **Pick your sound sources.** Choose what to record, then turn on your microphone. In the desktop app you can also take the audio playing on your machine. In the browser, tick the share audio box in your browser’s own dialog when you pick a tab. 2. **Record with a count-in.** A short count-in gives you time to get your first line ready. Pause and resume whenever you need to, and the paused time is folded out of the final length so the audio and the picture still line up. 3. **Balance the tracks and export.** The take lands on the timeline with your microphone as a separate track. Raise it, reduce background noise, add captions, then export. Every step runs on your device. ## FAQ **Can I record computer audio, not just my microphone?** Yes. The Mac and Windows apps record the audio playing on the whole machine alongside the picture. In the browser, Chrome and the other Chromium browsers can capture the audio of a tab you share, so pick a tab rather than a whole screen when the sound matters. **Why did my browser recording come out silent?** Browsers only include audio if you ask for it in their own share dialog, and the option is offered for a tab rather than a whole screen. Share the tab and tick the share audio box. For the audio of your whole machine, including apps outside the browser, use the desktop app. **Is my microphone a separate track?** Yes. Screen, microphone and camera are recorded separately, so you can raise your voice over the computer audio, clean it up, or remove it altogether without touching the picture. **Is my recording or my audio uploaded?** No. Recording, transcription, editing and export all happen on your device. Nothing is sent to a server, so there is no hosted copy of what your microphone picked up. **Can I fix the audio afterwards?** Yes. Reduce steady background noise, adjust levels, or add captions timed to your speech, all with the same on-device engine that handles the rest of the edit. ## Related tools - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Clean up audio in a video, reduce background noise](https://www.supercut.cc/tools/remove-background-noise) - [Adjust video volume online, louder or quieter](https://www.supercut.cc/tools/adjust-video-volume) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) --- # Record your screen and webcam at the same time > Record your screen and webcam together in the browser.

Supercut records your screen, your microphone and your camera as three separate tracks and never composites the camera into the picture, so the bubble is still an editable layer when the take is finished.

Supercut opens your devices before the screen picker, so their startup time never eats into the recording. 2. **Record all three at once.** Screen, microphone and camera roll together as separate tracks. The camera and microphone can only attach once the screen is already going, so each one records the gap it started with and is placed back in sync for you. 3. **Reposition the bubble, then export.** On the timeline the camera is its own item. Drag it to a corner, resize it, remove it, or let it react to a zoom on the screen underneath. Export a 4K mp4 when it looks right. ## FAQ **Is the webcam burned into the recording?** No. The camera is recorded as its own track and is only ever a layer on the timeline, so it stays movable, resizable and removable after the take. That is the main reason to record here rather than in a tool that composites the bubble in as it records. **Can I remove the camera later and keep the audio?** Yes. Delete the camera item and the microphone track carries on, so you end up with a clean screen recording and a voiceover. **Do the camera and the screen stay in sync?** Yes. The camera and microphone can only start once the screen is already rolling, so each records how late it was and is placed that far into the timeline. Pauses are folded out of all three the same way. **Do I need to install anything?** No. The browser recorder works in Chrome, Edge, Brave and Arc. The Mac and Windows apps add audio from the whole machine and zooms that follow your cursor. **Is any of this uploaded?** No. Your screen, your voice and your face are captured, edited and exported on your device. There is no server copy and no share link, because nothing leaves your machine. ## Related tools - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Picture-in-picture video, overlay a second clip](https://www.supercut.cc/tools/picture-in-picture) - [Record your screen with audio, system sound and mic](https://www.supercut.cc/tools/record-screen-with-audio) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) --- # Turn a screen recording into a GIF > Record your screen and export it straight to a GIF. Capture a region, trim to the moment, convert on your device. No upload, no account to get started. Source: https://www.supercut.cc/tools/screen-recording-to-gif A short looping GIF is often the clearest way to show a bug, a fix or one interaction in a doc, an issue or a pull request. Supercut records your screen, lets you keep only the seconds that matter, and exports a GIF from the same timeline, all on your own machine. Record just a region if only part of the screen is interesting, and the file stays small without any extra work. ## The prompt you would type ``` Trim to 0:03 to 0:07 and export a GIF ``` ## How it works 1. **Record just the part you need.** Capture a screen, a window, a tab, or a region you draw. A tight region is the single biggest thing you can do to keep a GIF small and readable. 2. **Trim to the moment.** The take lands on the timeline already framed. Cut it down to the interaction itself, and drop the setup and the pause at the end. 3. **Export a GIF.** Choose GIF on export. Supercut renders the same timeline it previews and converts it in one pass on your device, so the GIF and an mp4 of the same edit can never disagree. ## FAQ **How do I keep the GIF file small?** Three things do most of the work: record a region rather than the whole screen, trim to a few seconds, and export smaller than full resolution. GIF has no modern compression to fall back on, so length and pixel count are what decide the size. **Can I record only part of my screen?** Yes. Region capture lets you record a rectangle instead of a whole display, which is usually what you want for a GIF that will be viewed inline in a doc or an issue. **Do GIFs keep the audio?** No. The GIF format has no audio track at all. If your recording needs sound, export an mp4 instead, or export both from the same edit. **Can I convert a screen recording I already have?** Yes. Drop an existing recording in and convert it the same way, or use the video to GIF tool if you just want the conversion on its own. **Is my recording uploaded to convert it?** No. Recording and conversion both run on your device, so nothing is uploaded and there is no server copy of whatever was on your screen. ## Related tools - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Convert video to GIF, free, in your browser](https://www.supercut.cc/tools/video-to-gif) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) - [Record your screen with audio, system sound and mic](https://www.supercut.cc/tools/record-screen-with-audio) --- # Supercut use cases > Who Supercut is built for, across 13 audiences.

Supercut runs FFmpeg in your browser, ideal for legal, medical, unreleased, or sensitive footage. Source: https://www.supercut.cc/use-cases/private-video-editor Most online editors upload your master file to process it in the cloud. Supercut is the opposite: decode, edit, and export on your device. The only network call is your text prompt so the AI knows what to do. ## Why it fits - Footage never leaves your device, WebAssembly processing - Works offline mid-edit once the page is loaded - Face blur and on-device captions for sensitive subjects - Same account as CapCutGPT if you already subscribed ## Tools this use case leans on - [Blur faces in a video, private, on your device](https://www.supercut.cc/tools/blur-faces-in-video) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) ## FAQ **Who needs a private browser editor?** Anyone handling unreleased product footage, patient education clips, legal depositions, or personal family video who cannot risk cloud upload. **Can I verify nothing uploads?** Open DevTools, throttle to offline after the page loads, and finish an edit. Supercut keeps working because processing is local. **Is this different from CapCutGPT?** Same engine and privacy model. Supercut is the new brand name at supercut.cc. --- # For product demo videos > Record a product demo with your screen, voice, and camera, then ship it looking produced. Recording and export both run on your device, so an unreleased build never uploads. Source: https://www.supercut.cc/use-cases/product-demo-videos A demo is usually needed today, not next sprint. Supercut records your screen, microphone, and camera in one take, drops the result onto the Studio timeline with a backdrop and zooms already applied, and exports a 4K mp4 for the site or a GIF for the changelog. The build on your screen never leaves your machine. ## Why it fits - Record screen, microphone, and camera in one take, as three separate tracks - The camera is never composited in, so the bubble stays movable and removable after the take - On the macOS desktop app, zooms are anchored to the places you clicked - The take lands on the timeline with the demo look already on it, ready to trim - Export a 4K mp4 for a landing page or a GIF for a changelog post - Pre-release builds stay on your device, there is no upload and no watermark ## Tools this use case leans on - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Convert video to GIF, free, in your browser](https://www.supercut.cc/tools/video-to-gif) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) ## FAQ **Do I need to install anything to record a demo?** No. The browser recorder works in Chrome, Edge, Brave, and Arc with nothing to install. The desktop app adds full system audio, cursor tracking, and the click-anchored zooms that come from it. **Can it zoom in on the part of the UI I am talking about?** On the macOS desktop app it samples your cursor and your clicks while you record, then places the push-ins for you, and you can edit or delete any of them afterwards. In the browser there is no way to track the cursor outside the page, so you place the zooms yourself on the timeline. **Is my unreleased product safe?** The recording is captured, edited, and exported on your device. There is no server copy and no share link, so a pre-release build is never uploaded anywhere. **Can I get a GIF for the changelog as well?** Yes. Studio exports the same timeline as an mp4 or a GIF, so the two can never disagree about the edit. --- # For software tutorials and onboarding videos > Record how-to and onboarding walkthroughs for your help center, caption them on your device, and export without uploading customer accounts or internal tooling. Source: https://www.supercut.cc/use-cases/software-tutorials A help-center video goes stale the moment the UI changes, so the real requirement is making one quickly and remaking it just as quickly. Supercut records the walkthrough, seats it on a backdrop, transcribes on your device for captions, and exports with no upload step in the middle. ## Why it fits - Record a display, a window, or a single browser tab, with your voice over it - Push in on the control you just clicked instead of showing the whole window - Add captions transcribed on your device, so support videos read with the sound off - Record a replacement step and drop it onto the timeline when the UI changes - Internal tooling and real customer accounts on screen are never uploaded ## Tools this use case leans on - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) ## FAQ **Can I record just one window or one tab?** Yes. Pick a display, a window, or a single browser tab. On the desktop app, recording a whole display is what gives you cursor-follow zooms. **How are the captions made?** Transcription runs in your browser with Whisper. Tutorial audio, including anything you say about a customer, is not sent anywhere. **Can it record app sounds and system audio?** On the desktop app, yes, on macOS and Windows. In Chrome you can capture the audio from a tab you share. **What if I fluff a step halfway through?** You can pause and resume as often as you like, and the paused time is folded out of the final length. For a step you want to redo, keep rolling and cut it out on the timeline afterwards. --- # For async team updates > Record a screen share with your voice and camera instead of holding the meeting. It stays on your device, so internal dashboards and customer data are never uploaded. Source: https://www.supercut.cc/use-cases/async-team-updates The meeting that could have been a video is usually a screen, a voice, and two minutes. Supercut records all three, puts the take on a timeline that already looks finished, and gives you a file you own. That matters most when the screen has an internal dashboard or a customer list on it. ## Why it fits - Record the screen, your voice, and your camera in one pass, no invite needed - The camera bubble is its own layer, so it can move off whatever it is covering - A short count-in before you start, then pause and resume without leaving gaps - Trim the dead air, then compress so the file fits your chat tool - Nothing is uploaded and no link is generated, which is the point for internal screens ## Tools this use case leans on - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Compress a video online, smaller file, no upload](https://www.supercut.cc/tools/compress-video) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) ## FAQ **How does my team watch it if nothing is uploaded?** You export a file and share it the way your team already shares files: chat, email, a drive, or a doc. Supercut does not host a copy, which is the trade for footage that never leaves your machine. **How do I get the file under a chat size limit?** Ask Supercut to compress it. It re-encodes to a smaller file while keeping it watchable, and that runs on your device too. **Can I record my camera without it being baked into the screen?** Yes. Screen, microphone, and camera are recorded as three separate tracks, and the camera is never composited in. That is what keeps the bubble movable, resizable, and removable after the take. **Do I need the desktop app?** No. Chrome, Edge, Brave, and Arc record with nothing to install. The desktop app adds full system audio and cursor tracking, which is where the automatic zooms come from. --- # For TikTok creators > Reframe to 9:16, add viral captions, trim hooks, and export TikTok-ready clips in your browser.

Ask for bold, Hormozi-style, or minimal captions. Transcription runs on your device. **What about TikTok sounds?** Add trending audio inside TikTok after export. Supercut focuses on the video edit. --- # For podcast clips > Turn podcast episodes into captioned vertical clips for social. Transcribe and reframe in your browser without uploading raw audio or video.

Supercut blurs detected faces and you can describe other things to obscure. It all runs on your device, so sensitive listing footage is never uploaded. **How do I make a vertical listing video?** Ask Supercut to crop to 9:16. Smart reframe keeps the subject in frame as the camera moves through the property. **Do I need to upload client footage anywhere?** No. Everything is processed in your browser, which matters when you are handling clients, their homes, and personal details. --- # For course creators > Trim lessons, add captions for accessibility, clean up audio, and cut promo clips, all in your browser.

Source: https://www.supercut.cc/alternatives/capcut-alternative CapCut is powerful and popular, but using it means an account in the wider TikTok ecosystem, and its AI and cloud features process on its servers.

Supercut edits in your browser with plain-English prompts, on your device. Source: https://www.supercut.cc/alternatives/veed-alternative VEED is a polished cloud editor known for fast subtitles and a clean interface. The tradeoff is that you upload your footage to its servers, and the free tier adds a watermark. Supercut runs in your browser instead. Your footage stays on your device, and you edit by describing what you want in plain English. ## Why people switch **Your footage never leaves your device.** VEED is cloud-based, so your clips are uploaded to its servers to be edited and rendered. Supercut keeps everything local: decode, edit, and export all happen in your browser via WebAssembly. Only your text prompt is sent. **No waiting on uploads or renders.** With a cloud editor, larger files mean upload time before you can start and render time before you can download. Supercut works on the file already on your device, so there is no upload step. **On-device captions instead of cloud transcription.** VEED's subtitles are a real strength, generated in the cloud. Supercut also auto-captions, but transcription runs on your device with a local model, so your audio is never uploaded. **No account to try, and a simpler price.** Supercut lets you try your first export with no sign-up. The paid plan is a flat unlock: 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access. Cancel anytime. **Edit by typing.** Instead of clicking through panels, describe the edit: reframe to 9:16, add captions, speed up 2x. An AI plans it and a deterministic engine runs the FFmpeg operations on your machine. **Keeps working offline.** Because VEED renders in the cloud, it needs a connection. Once a Supercut page has loaded, you can keep editing offline. ## Supercut compared with VEED | | Supercut | VEED | | --- | --- | --- | | Privacy / upload | Stays on device, never uploaded | Footage uploaded to VEED servers | | Where it runs | Your browser via WebAssembly | The cloud on VEED servers | | Captions | On-device transcription | Cloud transcription | | How you edit | Plain-English prompts | Panel and timeline UI | | Watermark on free | Free first export, then flat paid unlock | Watermark on the free tier | | Account to start | None for your first export | Account based | | Best for | Private, fast solo edits | Polished subtitles and team marketing video | ## Where VEED is genuinely better VEED is genuinely strong as a cloud editor. Its auto-subtitles are fast and accurate, the interface is clean and beginner-friendly, and it bundles a screen recorder, brand kit, stock assets, and team features. For marketing teams who want a polished all-in-one cloud studio, VEED is a strong pick. ## FAQ **Is Supercut a good VEED alternative?** Yes for solo, privacy-first editing. Supercut covers trim, reframe, captions, color, speed, compression, and platform exports, all on your device. VEED's edge is polished cloud subtitles, a screen recorder, and team features. The core difference is that Supercut never uploads your footage. **Does Supercut add a watermark like VEED's free tier?** You can try your first export free. After a flat paid unlock, exports are watermark-free and every tool is open. VEED adds a watermark on its free tier. **Are Supercut's captions as good as VEED's?** Supercut auto-captions with a local model and times words to speech, with styles built for short-form. The difference is that transcription runs on your device, so your audio is never uploaded. **Do I need an account?** No account is needed to try your first export. VEED is account based. **How much does Supercut cost?** Free to try your first export, then 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access.

Supercut edits in your browser with plain-English prompts. Your video stays on your device. Source: https://www.supercut.cc/alternatives/kapwing-alternative Kapwing is a capable cloud editor, but to use it you upload your footage to its servers, where the editing and rendering happen. Supercut takes the opposite approach: your video never leaves your device. Editing runs in the browser through WebAssembly, and the only thing sent to the network is the text prompt that tells the AI what edit to plan. ## Why people switch **Your footage never leaves your device.** Kapwing is cloud-native, so your clips are uploaded and rendered on its servers. Supercut decodes, edits, and exports locally in your browser. The only thing that goes over the network is your text prompt, so there is nothing to upload and nothing to wait on. **Edit by typing what you want.** Kapwing drives editing through a drag-and-drop timeline plus AI tools. With Supercut you describe the edit in plain English, an AI plans it, and a deterministic engine maps it to FFmpeg operations. No timeline scrubbing required. **Keeps working offline.** Because Kapwing renders in the cloud, it needs a connection to process and export. Supercut runs in the browser via WebAssembly, so once the page has loaded you can keep editing offline. **Try a real export with no account.** Kapwing lets you start editing but typically asks you to sign up to save work and unlock the full toolset. Supercut lets you try your first export with no account at all. **No upload limits on the files you edit.** Most cloud editors cap free usage around things like export count, video length, resolution, and storage on their servers. Supercut processes locally, so the size of your footage is bounded by your own device, not an upload quota. **Watermark-free output and every tool on the paid plan.** Both tools gate unlimited exports behind a paywall, and both add a watermark on the free tier. With Supercut, the paid plan removes the watermark and unlocks all 40+ tools, from 4.99 per month billed yearly (59.88 per year), or 9.99 per month monthly, or 199 once for lifetime access.

Supercut covers 40+ common operations like trim, crop and reframe, captions, color filters, speed changes, compression, and platform export presets. The big difference is where the work happens: Supercut runs in your browser and keeps your footage on your device, while Kapwing uploads and renders in the cloud. If your main need is real-time team collaboration, Kapwing's shared workspaces are still its strength. **Does Supercut upload my video like Kapwing does?** No. Kapwing is cloud-native, so your footage is uploaded to its servers to be edited and rendered. Supercut decodes, edits, and exports entirely in your browser. The only thing sent to the network is your text prompt, so the AI knows what edit to plan. **Do I need an account to try Supercut?** No. You can try your first export with no account.

Supercut edits in your browser with plain-English prompts, and your footage stays on your device. Source: https://www.supercut.cc/alternatives/clipchamp-alternative Clipchamp is Microsoft's browser-based editor, now built into Windows. It is approachable, but it expects an account (a Microsoft account on Windows) and now keeps your projects in OneDrive. Supercut runs in any browser with no account to start, keeps your footage on your device, and lets you edit by typing what you want. ## Why people switch **No Microsoft account required.** Clipchamp requires you to sign in to use it and save projects (a Microsoft account on Windows; the browser version also allows Google or email sign-in). Supercut needs no account to try your first export, and there is no ecosystem to join. **Runs in any modern browser.** Clipchamp runs in Chrome or Edge on several systems but is built around Windows and Microsoft 365, and it does not support Safari or Firefox. Supercut runs in any modern browser on Mac, Windows, Linux, or Chromebook, with identical on-device editing. **Your footage stays on your device.** Supercut decodes, edits, and exports locally in your browser via WebAssembly. The only thing sent over the network is your text prompt, so there is nothing to upload. Clipchamp also processes media on your device, but it now requires your projects to live in OneDrive to stay editable, so your work lives in the cloud. **Edit by describing the result.** Instead of arranging a timeline, say what you want: trim, reframe to 9:16, add captions, compress. An AI plans the edit and a deterministic engine runs it on your machine. **Works offline once loaded.** Once a Supercut page has loaded, you can keep editing offline, because the engine runs locally rather than relying on cloud project storage. **Watermark-free on a simple paid plan.** Supercut is free to try your first export.

Supercut edits on your device with plain-English prompts. Source: https://www.supercut.cc/alternatives/descript-alternative Descript is a powerful editor (a desktop app plus a cloud web app) built around editing video and audio through a transcript. Either way, it uploads your media to the cloud for transcription and processing. Supercut takes a lighter, more private path. It runs in your browser with nothing to install, keeps your footage on your device, and edits from plain-English prompts. ## Why people switch **Nothing to install.** Descript runs as a Mac and Windows desktop app and a cloud web app. Supercut runs in any modern browser, so there is no download and no platform requirement. **Your media is never uploaded.** Descript uploads media to the cloud for transcription and processing. Supercut decodes, edits, and exports locally via WebAssembly. Only your text prompt is sent. **On-device captions.** Both tools transcribe, but Supercut runs transcription on your device with a local model, so your audio stays on your machine. Good for sensitive interviews and unreleased recordings. **Prompt-based editing for quick clips.** Descript edits by editing the transcript, which is excellent for long-form. For fast, common edits like trim, reframe, captions, and export, Supercut lets you just say what you want. **No account to try, simpler price.** Supercut is free to try your first export with no sign-up. The paid plan is flat: 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access. Cancel anytime. **Works offline once loaded.** Because the engine runs locally, you can keep editing offline after the page loads, without round-trips to a cloud service. ## Supercut compared with Descript | | Supercut | Descript | | --- | --- | --- | | Privacy / upload | Footage and audio stay on device | Media uploaded to the cloud for transcription | | Where it runs | Any browser, no install | Desktop app and cloud web app (media goes to the cloud) | | How you edit | Plain-English prompts | Transcript-based editing | | Captions | On-device transcription | Cloud transcription | | Account to start | None for your first export | Account required | | Works offline | Yes, once the page loads | Cloud features need a connection (desktop app has limited offline editing) | | Best for | Fast, private clip edits | Podcasts and long-form transcript editing | ## Where Descript is genuinely better Descript is genuinely excellent for long-form and spoken-word work. Transcript-based editing, multitrack timelines, Studio Sound, Overdub, and screen recording make it a favorite for podcasters and video teams who work with a lot of dialogue. For that workflow, Descript is best in class. ## FAQ **Is Supercut a good Descript alternative?** It depends on your workflow. Descript shines for long-form, transcript-driven editing of podcasts and talking-head video. Supercut is built for fast, private edits of clips: trim, reframe, captions, color, audio cleanup, and platform exports, all on your device with no upload. **Does Supercut upload my audio or video like Descript?** No. Descript uploads media to the cloud for transcription and processing. Supercut runs transcription and editing on your device, so nothing is uploaded except your text prompt. **Can Supercut caption my videos?** Yes.

Supercut edits in your browser, never uploads your footage, and runs on plain-English prompts. Try your first export free. Source: https://www.supercut.cc/alternatives/canva-alternative Canva is a cloud design suite. You sign into an account, footage you add lands in your media library, and the heavy lifting happens on Canva's side. Supercut takes the opposite approach. Decode, edit, and export all run on your device in the browser, and the only thing that leaves your machine is your text prompt. You describe the edit in plain English, an AI plans it, and a deterministic engine maps it to FFmpeg operations. ## Why people switch **Your footage never gets uploaded.** When you add a video to a Canva design, it goes into your Canva media library and processing happens in the cloud. Supercut keeps source files on your machine. There is nothing to sync, account-lock, or breach on a server, because the video never leaves your device. **You edit by describing, not by building a canvas.** Canva is template and asset driven. You build inside its editor around its stock library and brand kit. Supercut is prompt driven. Type what you want, like trim to the first 30 seconds, reframe to 9:16, add captions, and the engine handles the FFmpeg work across 40+ tools. **Try your first export without an account.** Canva is account based, so you typically sign in before you can work and download. Supercut lets you run your first export with no sign-up, so you can see the result before deciding anything. **It keeps working offline mid-edit.** Cloud editors generally need a connection to load and save your work. Once a Supercut page has loaded, it keeps editing offline mid-session, because the engine runs locally in your browser. **A flat paywall, not asset-by-asset surprises.** Canva's free tier can export many videos, but Pro templates, Pro stock, or other premium assets can trigger an upgrade prompt at download. Supercut is free to try your first export, then one flat unlock removes watermarks and opens every tool: 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access.

No canvas to fill, no asset library to learn. ## Supercut compared with Canva | | Supercut | Canva | | --- | --- | --- | | Privacy and upload | Footage stays on device, never uploaded | Footage uploads to your media library | | Where it runs | In your browser via WebAssembly | In the cloud on Canva's side | | How you edit | Plain-English prompts to an engine | Templates, stock, and a manual canvas | | Account to start | No account for your first export | Account based sign-in | | Watermark on export | None after a flat paid unlock | Premium assets can prompt an upgrade | | Offline use | Keeps working once the page loads | Generally needs a connection | | Best for | Private, fast edits to real footage | Templated graphics and team design | ## Where Canva is genuinely better Canva is genuinely strong as an all-in-one design suite. It has a huge library of templates, stock media, fonts, and brand assets, plus real-time team collaboration and cloud access from any device. For social graphics, presentations, and quick branded videos built from templates, it is hard to beat, especially for non-editors and teams who want a polished result fast without touching a timeline. ## FAQ **Is Supercut a full Canva replacement?** Not for everything. Canva is a broad design suite for graphics, presentations, and templated content with team collaboration. Supercut is focused on editing video itself: trimming, reframing, captions, color, audio, and platform exports. If your work is mostly cutting and shaping real footage, Supercut covers it. If you need a stock library and brand templates, Canva is built for that. **Does Supercut upload my video like Canva does?** No. Canva uploads video you add to your media library and processes it in the cloud. Supercut decodes, edits, and exports on your device in the browser. The only thing sent over the network is your text prompt, so the AI knows which edit to plan. **Do I need an account to use Supercut?** No account is needed to try your first export.

Cloud editors generally need a connection to load and save your work. **How does prompt-based editing work?** You describe the edit in plain English, like reframe to 9:16 and add captions. An AI plans the edit and a deterministic engine maps it to FFmpeg operations across 40+ tools, then runs them on your device. --- # Supercut: a Loom alternative that records on your device > Looking for a Loom alternative that does not upload your recording? Supercut records your screen, mic and camera on your device, then edits and exports locally. Source: https://www.supercut.cc/alternatives/loom-alternative Loom made the async video message normal: hit record, stop, paste a link. That convenience is built on its cloud, so the recording is uploaded to Loom, hosted there, and watched through a link on its servers. Supercut captures the same three sources, screen, microphone and camera, and keeps every one of them on your device. There is no upload and no hosted copy, which also means you end up with a file you can put wherever you want. ## Why people switch **The recording never leaves your device.** With Loom, recording and hosting are the same act: the video goes to its servers so it can be watched at a link. Supercut records to your own disk and edits and exports there too. Nothing is uploaded, so there is no server copy of a screen that may have had your inbox, a dashboard or a customer's data on it. **You get a file, not a link.** Loom's share link is the product, and it is a good one. It is also the only copy unless you download it. Supercut hands you a finished 4K mp4 or a GIF at the end, so the recording goes into your own drive, your docs, your help centre or an upload to YouTube, on your terms. **A full editor, not only a recorder.** Loom keeps editing deliberately light so recording stays fast. In Supercut the take lands on a multitrack timeline: trim it, add zooms, burn in captions, crop, drop in other footage, swap the audio, then export. The recording is the start of the edit rather than the whole of it. **The camera stays its own layer.** Supercut records the screen, the microphone and the camera as three separate tracks and never composites the bubble into the picture. That is what lets you move it, resize it or delete it after the take, instead of deciding its position before you have seen the recording. **Zooms that follow your cursor, and captions made locally.** The macOS app samples the cursor and captures clicks while you record, so it can put a push-in on the thing you just clicked, and you can edit or remove any of them afterwards. Captions are transcribed on your machine with a local model, so your audio is not sent anywhere to be turned into text. **One flat price, and no per-seat maths.** Supercut is free to try your first export. One flat unlock removes watermarks and opens every tool: 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access. Cancel anytime. ## Supercut compared with Loom | | Supercut | Loom | | --- | --- | --- | | Where the recording lives | On your device only | Uploaded to Loom and hosted there | | How you share | Export the file and share it however you like | A share link on Loom, with viewer analytics | | Editing after the take | Multitrack timeline: zooms, captions, crop, other footage | Light editing built around the recording | | Captions | Transcribed on your device | Cloud transcription | | Where it runs | Browser, plus Mac and Windows apps | Browser, desktop apps and mobile | | Account to start | None for your first export | Account based | | Best for | Demos and product videos you want to keep and edit | Fast async messages your team watches in one place | ## Where Loom is genuinely better Loom is genuinely excellent at what it was built for. Recording to a link that plays instantly, viewer analytics, comments and reactions pinned to the timeline, embeds that work in the docs and tickets teams already live in, plus mobile apps, shared libraries and admin controls. If the point of the video is that a colleague watches it today and replies on it, Loom's hosted model is the reason it works so well. ## FAQ **Is Supercut a good Loom alternative?** It depends what you want the video to do. Loom is built around a hosted link your team watches and comments on. Supercut is built around a recording you keep and edit: it captures screen, mic and camera on your device, drops the take onto a timeline with zooms, captions and a framed look, and exports a file. If you need hosting, analytics and comments, Loom does that and Supercut does not. **Does Supercut upload my recording or give me a share link?** Neither. Recording, editing and export all run on your device, so there is no server copy and no link to expire or leak. You export the finished file and decide where it goes. **Can Supercut record my screen, microphone and camera at once?** Yes, as three separate tracks. Because the camera is never composited into the picture during capture, you can move, resize or remove the bubble after you have watched the take back. **Does it work in a browser, or do I need the app?** The browser recorder works in Chrome, Edge, Brave and Arc with nothing to install, and it can capture the audio of a shared tab. The Mac and Windows apps add audio from the whole machine and cursor-driven zooms, which a browser cannot do because it cannot see your cursor outside the page. **How much does Supercut cost?** Free to try your first export, then 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access. Cancel anytime. --- # Supercut: a Screen Studio alternative that is not Mac only > Looking for a Screen Studio alternative that runs beyond macOS? Supercut records polished demos in the browser or on Mac and Windows, and edits them too. Source: https://www.supercut.cc/alternatives/screen-studio-alternative Screen Studio is a native Mac app that set the bar for demo videos: automatic zooms, smoothed cursor motion, and a backdrop that makes a plain screen capture look deliberate. It is very good at that. Two things send people looking for something else: it runs on macOS only, and it is a paid app. Supercut records the same kind of polished demo, framed on a backdrop with padding, rounded corners and a shadow already applied, and it runs in a browser as well as on Mac and Windows. It is also a full editor, so the take is the start of the edit rather than the end of it. ## Why people switch **It is not macOS only.** Screen Studio is a Mac app, so on Windows or a Chromebook it is simply not an option. Supercut records in Chrome, Edge, Brave and Arc with nothing to install, and ships Mac and Windows apps for the deeper capture. Same product, same look, whichever machine you are sitting at. **Nothing to buy before you see the result.** You can open the browser recorder, record a demo and try an export without installing an app or paying up front. Supercut is free to try your first export, then one flat unlock removes watermarks and opens every tool. **A recorder and an editor in one place.** Screen Studio is focused on polishing the recording itself, and it is deliberately narrow about that. In Supercut the take lands on a multitrack timeline, so you can trim, add on-device captions, crop, cut in other footage, replace the audio, and export a 4K mp4 or a GIF from the same document. **Local on both, and local in the browser too.** This is not a privacy argument. Screen Studio is a native app that records and exports on your Mac, and that is one of its virtues. The honest difference is that Supercut keeps the same promise in the browser: the recording is decoded, edited and exported in the page on your machine, with nothing uploaded and no share-link copy on a server. **The camera bubble stays editable after the take.** Screen, microphone and camera are recorded as three separate tracks, and the camera is never composited into the picture. Move it, resize it, or drop it entirely once you have watched the recording back, rather than committing to a layout before you press record. **A flat price with a lifetime option.** Supercut is 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 once for lifetime access, and the same unlock covers every tool, not just the recorder. Cancel anytime. ## Supercut compared with Screen Studio | | Supercut | Screen Studio | | --- | --- | --- | | Platforms | Browser (Chrome, Edge, Brave, Arc), plus Mac and Windows apps | macOS only | | To try it | Nothing to install in the browser | A native Mac app to download | | Automatic zooms | Cursor-driven in the desktop apps, click-anchored on macOS. You place them yourself in the browser. | Automatic cursor-driven zooms | | Where the recording lives | On your device, browser included | On your Mac | | After the recording | Full multitrack timeline, captions, other footage | Focused on polishing the recording itself | | Price | Free first export, then a flat unlock | Paid app | | Best for | Demo videos you also need to edit, on any platform | Beautifully polished Mac-native screen recordings | ## Where Screen Studio is genuinely better Screen Studio is genuinely excellent, and it earned its reputation. Its automatic zooms and smoothed cursor motion are the reference implementation everyone else is measured against, the backdrops and window framing look considered out of the box, and being a native Mac app it captures high-resolution displays smoothly and keeps everything on your machine. If you are on a Mac and the job is one beautiful screen recording, it is a very easy tool to recommend. ## FAQ **Is there a Screen Studio for Windows?** No. Screen Studio is a macOS app. If you are on Windows and want the same kind of polished demo, Supercut has a Windows app that records the screen with system audio and cursor-driven zooms, plus a browser recorder that needs nothing installed at all. **Does Supercut do automatic zooms like Screen Studio?** In the desktop apps, yes. They sample your cursor while recording, and on macOS they also capture clicks, so a push-in lands on the thing you just clicked. Every zoom is an editable item afterwards, so you can retime or delete it. In the browser there is no way to track a cursor outside the page, so you place zooms yourself on the timeline. **Do I have to install anything to try Supercut?** No. The browser recorder works in Chrome, Edge, Brave and Arc, and it can capture the audio of a shared tab. Install the Mac or Windows app when you want audio from the whole machine and cursor-driven zooms. **Does my recording get uploaded?** No. Recording, editing and export all happen on your device, in the browser or in the desktop app. Screen Studio also keeps your recording on your Mac, so on this point the two are alike.

Crop or reframe in your browser by typing a prompt. Nothing uploads. Source: https://www.supercut.cc/learn/how-to-make-a-video-vertical Published: 2026-06-17 TikTok, Reels, and Shorts all want a tall 9:16 frame, but most footage is shot wide in 16:9. Making it vertical means cropping or reframing so your subject fills a portrait screen instead of sitting in a small letterboxed strip. In Supercut you do this by typing a plain-English prompt, and the whole job runs in your browser, so your footage is never uploaded. ## What vertical actually means (9:16 vs square vs wide) Vertical video means a 9:16 aspect ratio: nine units wide for every sixteen units tall. That is the full-screen shape for TikTok, Instagram Reels, and YouTube Shorts, and 1080x1920 is the common upload size. By contrast, 16:9 is the wide format from most cameras and screen recordings, and 1:1 is the square middle ground that suits older feed posts. Drop a 16:9 clip straight into a vertical feed and the platform usually pads it with black or blurred bars, so the actual picture sits in a thin band in the middle. Converting to true 9:16 fills the screen instead. ## Crop vs reframe: pick the right approach There are two honest ways to go vertical. A straight crop keeps a fixed tall slice of the frame, which is fast and works when your subject stays put, for example a centered talking head. Smart reframe is better when the subject moves: it tracks faces on your device and pans the 9:16 window to follow them, so a person walking across a wide shot stays inside the vertical cut. Supercut supports both. Use a plain crop for static shots, and smart reframe for anything with movement or a subject who drifts away from center. ## Do it in your browser, with nothing uploaded Supercut runs FFmpeg in your browser through WebAssembly, so decoding, cropping, reframing, and exporting all happen on your own device. Your video file never leaves your computer. Only the short text prompt you type is sent, so the AI can plan the edit. That means you can reframe sensitive or unreleased footage without handing it to a server, and once the page has loaded you can keep working even if your connection drops. ## Steps 1. **Open your clip in the browser.** Open the Supercut editor and drag your video in. It loads straight into the page on your device. No upload, and no account is needed to try your first export. 2. **Type a plain-English prompt.** Say what you want, for example "crop this to 9:16 vertical for TikTok" or "smart reframe to 9:16 and keep my face centered." The AI plans the edit and a deterministic engine maps it to the exact FFmpeg crop. 3. **Check the vertical frame.** Look at the result and confirm your subject sits inside the tall 9:16 window with a little headroom. If the framing is off, refine your prompt, for example "shift the crop left" or "use smart reframe instead." 4. **Add captions or a platform preset (optional).** Useful for social: ask for auto-captions, generated on-device with Whisper, or apply a platform export preset for TikTok, Reels, or Shorts so the size matches where you are posting. 5. **Export and download.** Export the finished 9:16 clip and save it to your device. The encode runs locally, so your footage is never sent anywhere, and you get a vertical file ready to post. ## Tips - Leave headroom when you shoot wide so faces are not clipped when you crop to a narrow 9:16 window. - Use smart reframe for any clip where the subject moves, and a plain crop for static talking-head shots. - Reframe to 9:16 first, then add captions, so the text is sized for the vertical frame and does not cover the subject. - Aim for a 1080x1920 source so the exported 9:16 clip stays sharp on a full-screen phone. ## FAQ **What aspect ratio should a vertical video be?** Use 9:16 for TikTok, Instagram Reels, and YouTube Shorts, with 1080x1920 as the standard full-screen size. Square (1:1) and wide (16:9) are different shapes that will not fill a vertical feed. **Will I lose quality turning a horizontal video vertical?** Cropping to 9:16 keeps a tall slice of the original frame, so the kept area stays as sharp as the source; you are trimming the sides, not stretching pixels. Avoid scaling a small clip up past its native resolution, since that is where softness creeps in. Doing the edit in one pass in Supercut keeps quality loss minimal. **Does my video get uploaded to make it vertical?** No. Supercut decodes, crops or reframes, and re-exports entirely in your browser via WebAssembly, so your footage never leaves your device. Only the text prompt you type is sent, so the AI can plan the edit. **How do I keep my subject centered when the shot moves?** Use smart reframe instead of a fixed crop. It tracks faces on your device and pans the 9:16 window to follow the subject, so someone moving across a wide frame stays inside the vertical cut. Just ask for "smart reframe to 9:16." **Can I make a vertical video for free?** You can try your first export free with no account.

On-device transcription times each word to your speech, and nothing uploads. Source: https://www.supercut.cc/learn/how-to-add-subtitles-to-a-video Published: 2026-06-18 Captions make videos watchable on mute, easier to follow, and more accessible. The old way meant typing every line by hand or uploading your footage to a transcription service. With Supercut you type one plain-English prompt, the audio is transcribed on your own device, and the captions are timed to your speech automatically. Your footage never leaves your browser. ## Subtitles vs captions: what you actually want People use the words interchangeably, and for most short-form video the difference does not matter. Subtitles usually mean a text version of the spoken words, often used for translation. Captions usually mean on-screen text styled for the video, the kind you see in TikToks and Reels where each word pops as it is spoken. Supercut generates spoken-word captions: it transcribes your audio, times each word, and burns the text into the video so it plays the same everywhere, with no separate subtitle file to manage. ## How Supercut captions a video You do not scrub a timeline or type lines into boxes. You drop a clip into the editor, type something like "add captions, big bold style," and an on-device Whisper model transcribes the audio and times the words to your speech. Because transcription runs in your browser through WebAssembly, your video and its audio stay on your machine. Nothing is uploaded to a server. The first caption request downloads the transcription model (about 39 to 74 MB), then it runs locally from there, even offline once the page is loaded. ## Styling, fixing typos, and exporting Pick a caption style built for short-form video, then preview the result before you commit. If the transcription got a name or a term wrong, you can adjust the caption text and restyle before exporting, so typos are easy to fix. When it looks right, export. The captions are baked into the file, ready to post to TikTok, Reels, or Shorts with no extra subtitle track to upload. Pair captions with a 9:16 reframe and a trim and you have a finished short in a few prompts. ## Steps 1. **Drop your clip into the browser.** Open the Supercut editor and drag in your video. It loads straight into your browser. There is no upload, and you can try your first export without an account. 2. **Type the caption prompt.** In plain English, type something like "add captions" or "add captions, big bold style." The on-device model transcribes the audio and times each word to your speech automatically. 3. **Preview and fix the text.** Watch the captioned preview. If a name or word came out wrong, edit the caption text and adjust the style before you commit. Nothing has left your device at this point. 4. **Export with captions baked in.** Export the clip. The captions are burned into the video file, ready to post to TikTok, Reels, Shorts, or anywhere else, with no separate subtitle file to manage. ## Tips - Say the style you want in the same prompt, for example "add captions, big bold style," so you skip a step. - Captions are timed to your audio, so cleaner sound means cleaner timing. If the recording is noisy, run a noise-removal prompt first, then caption. - Proper nouns and brand names trip up any transcriber. Skim the preview and fix those words before exporting. - Caption first, then reframe to 9:16, so you can see exactly where the text sits in the vertical frame. ## FAQ **Does adding captions upload my video or audio?** No. Transcription runs on your device with an in-browser model, and the whole edit happens in your browser. Your video and its audio never leave your computer. **Do the captions sync to the words being spoken?** Yes. Supercut times the captions to your speech so each word appears as it is spoken, using caption styles built for short-form video. **Can I fix a typo or a misspelled name?** Yes. You can edit the caption text and restyle it before exporting, so wrong names, terms, or typos are easy to correct. **What languages can it caption?** The on-device transcription model handles a wide range of spoken languages. Accuracy is best with clear audio, so reduce background noise first if the recording is rough. **Are captions free?** You can try your first export with no account. Unlimited watermark-free exports and every tool are part of a paid plan: from 4.99 per month billed yearly (59.88 per year), 9.99 per month on a monthly plan, or 199 as a one-time lifetime purchase.

A clear, practical guide, plus how to do it in your browser with Supercut, where nothing uploads. Source: https://www.supercut.cc/learn/how-to-compress-a-video Published: 2026-06-19 A big video file is easy to make and hard to share. The good news: most footage can shrink a lot before you notice any drop in quality, because modern encoders throw away data your eyes barely register. This guide explains what actually controls quality, then shows how to compress a clip in your browser with Supercut, where the footage never leaves your device. ## What actually decides quality and file size Three things drive file size: resolution (the pixel dimensions), bitrate (how much data each second of video gets), and the codec doing the encoding. Most of the quality loss people complain about comes from a heavy-handed bitrate cut, not from compression itself. A smarter approach is constant-quality encoding (CRF, in H.264 terms), where the encoder spends bits where the picture needs them and saves bits on flat or still areas. You keep detail in the parts you look at while still cutting the overall size. Resolution matters just as much. A 4K phone clip watched on a phone or in a feed has far more pixels than the screen will ever show. Downscaling 4K to 1080p, or 1080p to 720p, can shrink the file substantially with no visible loss for social or messaging, because you are throwing away pixels nobody was going to see. ## How to compress without losing much quality Start with the codec. H.264 (MP4) is the safe, universal choice and plays everywhere. Newer codecs can squeeze harder, but H.264 is the best balance of size, quality, and compatibility for anything you plan to send to other people. Keep audio sensible too: around 128 kbps is plenty for most speech and music, and going lower saves little while being easy to hear. Then match the output to where it is going. For email or chat, downscale to 1080p or 720p and let constant-quality encoding handle the rest. For a platform like TikTok or YouTube, export close to its native size so the platform does not re-compress an already-compressed file a second time. The single habit that hurts quality most is compressing the same clip over and over, so do it once, from the highest-quality source you have. ## Compressing in Supercut (in your browser, nothing uploads) Supercut compresses video entirely on your device using FFmpeg compiled to WebAssembly. Your footage never gets uploaded. Only the text of your prompt is sent, so the AI knows what edit to plan, then a deterministic engine maps that to the right encoding settings and runs them locally in your browser. There is no upload step, so a large 4K file starts processing right away instead of crawling through your connection. Once the page has loaded, the work even keeps running if your connection drops mid-edit. You type what you want in plain English, watch the result in the preview, and download. Nothing to learn, and no copy of your file sitting on someone else's server. ## Steps 1. **Open Supercut and drop in your clip.** Open the editor and drag your video into the browser. It loads locally on your device. No upload, and no account needed to try your first export. 2. **Type a plain-English compress prompt.** Say what you want, like "compress this video to a smaller size" or "compress and downscale to 720p for email." Supercut plans the edit and picks encoding settings that cut size while keeping the clip watchable. 3. **Check the preview.** Watch the compressed clip in the preview and confirm it still looks sharp. Want it smaller? Ask for a lower resolution. Want more detail back? Ask to keep it at the source size. 4. **Export and download.** Export the smaller file and save it. The whole process ran in your browser, so the original footage never left your device. ## Tips - Downscale before you cut bitrate. Dropping 4K to 1080p shrinks the file a lot with little to no visible loss on phones or in feeds. - Compress once, from your best source. Re-compressing an already-compressed file is what makes video look blocky. - Keep audio around 128 kbps for speech and music. Pushing it lower saves little and is easy to hear. - Export close to the target platform's size so it does not re-compress your file a second time. ## FAQ **Can you compress a video without losing quality at all?** Not literally zero, but you can get very close. Constant-quality encoding and a sensible resolution let you cut file size a lot while keeping the picture sharp enough that most viewers see no difference. The visible loss usually comes from over-aggressive bitrate cuts or from compressing the same clip several times. **Does Supercut upload my video to compress it?** No. Compression runs in your browser with WebAssembly, so the file never leaves your device. Only your text prompt is sent, so the AI can plan the edit. **How small can the file get?** It depends on the clip and how much quality you want to keep. Lowering the resolution and using constant-quality encoding can cut size dramatically. You preview the result and can ask for smaller or higher quality before you export. **What format should I compress to?** MP4 with H.264 is the best default. It plays on virtually every device and platform and balances small size with good quality. Supercut can also convert between common formats if you need something else. **Is Supercut free to compress a video?** You can try your first export free with no account. After that, a paid plan unlocks unlimited watermark-free exports and every tool, starting at 4.99 a month billed yearly, with monthly and one-time lifetime options. You can cancel anytime. ## Do it in Supercut - [Compress a video online, smaller file, no upload](https://www.supercut.cc/tools/compress-video) - [Resize a video online, change resolution, no upload](https://www.supercut.cc/tools/resize-video-online) - [Convert video to MP4 online, universal format](https://www.supercut.cc/tools/convert-to-mp4) --- # How to trim or cut a video > Trim or cut a video in your browser. Type the range you want to keep in plain English, run it, and export. Your footage never gets uploaded. Source: https://www.supercut.cc/learn/how-to-trim-a-video Published: 2026-06-20 Trimming a video means keeping the part you want and dropping the rest: dead air at the start, a long pause in the middle, or a few seconds off the end. Supercut does it in your browser, with no software to install and no file to upload. You describe the cut in plain English and a deterministic engine runs it on your device. ## Trim versus cut: what each one means People use the words interchangeably, but they describe slightly different jobs. Trimming usually means shortening a clip from one or both ends, like dropping a slow intro or a hanging outro. Cutting can mean the same thing, or it can mean removing a section from the middle and joining what is left. Both come down to choosing a range to keep and discarding the rest. The one thing to have ready is your timestamps. Watch the clip and note where the good part begins and ends, in minutes and seconds. With Supercut you type those numbers into a prompt instead of dragging handles on a timeline, so having them noted makes the cut exact on the first try. ## How trimming works in Supercut Supercut runs entirely in your browser using WebAssembly (FFmpeg.wasm). When you add a clip, it loads into the page on your own machine. Your footage is never uploaded to a server. The only thing that leaves your device is the text of your prompt, so the AI can plan the edit. It turns your plain-English request into a precise trim command, and the engine executes it locally. Because the file stays on your device, it never sits on someone else's server and you keep control of the output quality. Once the page has loaded, the trim itself even works offline. ## Writing a good trim prompt There is no timeline to scrub. You type what you want, and specific prompts give the cleanest cut. Good examples: "trim from 0:05 to 0:20", "cut the first 10 seconds", "keep only the last 30 seconds", or "remove from 1:15 to 1:40". Write timestamps in minutes and seconds so the range is unambiguous. Need more than one change? Trim first, then ask for the next edit in the same session, like adding captions or cropping to 9:16 for TikTok or Reels. Each operation builds on the result of the last. ## Steps 1. **Add your clip in the browser.** Open the Supercut editor and drop your video in. It loads straight into your browser on your device. There is no upload, and no account is needed to try your first export. 2. **Describe the cut in plain English.** Type the range you want, such as "trim from 0:05 to 0:20" or "cut the first 10 seconds." Supercut reads the prompt and plans the exact trim, then maps it to a deterministic command. 3. **Run it and check the result.** The trim runs locally and you get the result back in the editor. If the range is off, edit your prompt and run it again until it lands where you want. 4. **Export and download.** Export the trimmed video and save it to your device. The file stayed on your machine the whole time, so nothing was ever uploaded. ## Tips - Note your start and end timestamps before you start, in minutes and seconds, so the prompt is exact. - To cut a chunk from the middle, describe the section to remove ("remove from 1:15 to 1:40") instead of listing the parts to keep. - Trimming works from your source file, so you set the export settings and decide the final resolution and size. - Chain edits in one session: after trimming, ask for "add captions" or "crop to 9:16" to finish a clip without starting over. ## FAQ **Is my video uploaded when I trim it?** No. Supercut trims your clip entirely in your browser using WebAssembly. The video never leaves your device. Only the text of your prompt is sent, so the AI knows where to cut. **What video formats can I trim?** Common formats like MP4, MOV, and WebM. You can also convert to a different format on export if you need one. **Will trimming reduce the video quality?** Trimming works from your source file. You choose the export settings, so you decide the final resolution and size. **Can I cut a section out of the middle of a video?** Yes. Describe the section to remove, like "remove from 1:15 to 1:40," and Supercut keeps the parts before and after and joins them. **Do I need an account to trim a video?** You can try your first export with no account.

Drop the file, type a prompt, export. Nothing uploads, your footage stays on your device. First export is free. Source: https://www.supercut.cc/learn/how-to-convert-mov-to-mp4 Published: 2026-06-21 MOV is Apple's default video format. It is great on a Mac or iPhone but awkward to share with people on Windows, Android, or some social apps. MP4 plays almost everywhere. With Supercut you convert MOV to MP4 by typing a plain-English prompt in your browser. Your video never leaves your device, and the first export is free with no account. ## MOV vs MP4: what is actually different MOV and MP4 are both containers. A container wraps the video and audio streams inside one file. They are close cousins: both commonly hold H.264 or HEVC video and AAC audio. The real difference is reach. MOV (.mov) was built by Apple for QuickTime and is what your iPhone and Mac record by default. MP4 (.mp4) is the universal standard that Windows, Android, web browsers, editing tools, and every major social platform accept without complaint. That overlap is why converting MOV to MP4 is usually quick and clean. You are mostly changing the wrapper, not rebuilding the video, so quality stays high. In Supercut you describe the conversion in plain English and a deterministic engine maps it to the right FFmpeg settings before anything runs. ## Why convert in your browser instead of uploading Most online converters ask you to upload your video to their servers, wait in a queue, then download the result. That means a copy of your footage sits on someone else's machine, and large MOV files from a phone or camera can take a long time to send. Supercut runs the conversion on your own device using WebAssembly (FFmpeg compiled to run in the browser). The file is read locally, converted locally, and saved locally. Nothing is uploaded. Only the text of your prompt is sent, so the AI knows you want an MP4. Once the page has loaded you can even go offline and the conversion still works. ## What to do after converting An MP4 is the right starting point for almost any next step. If the file is still too big to email or upload, compress it. If you are posting to TikTok, Reels, or Shorts, reframe it to a vertical aspect ratio. If you only need the sound, pull the audio out as an MP3. Everything works the same way in Supercut: drop the clip, type what you want, confirm, export. You can also stack requests in one prompt, for example convert to MP4 and trim the first five seconds together, so you rarely need a separate app for each task. ## Steps 1. **Open Supercut and drop in your MOV.** Go to supercut.cc and drag your .mov file into the browser, or click to pick it from your device. The file loads locally. It is not uploaded anywhere. 2. **Type a plain-English prompt.** In the command box, type something like "convert this to MP4". The AI plans the edit and a deterministic engine maps it to the right FFmpeg settings. You can ask for more in the same prompt, such as "convert to MP4 and compress for email". 3. **Confirm the planned edit.** Supercut shows you the operation it is about to run so you can check it matches what you wanted. If it is off, reword the prompt and try again before you export. 4. **Export the MP4.** Click export. The conversion runs on your device and saves a new .mp4 file. Your first export is free with no account. Paid plans unlock unlimited watermark-free exports and every tool. ## Tips - Converting MOV to MP4 is mostly a container change, so it is fast and keeps quality high. - Need a smaller file for email or messaging? Add "and compress" to your prompt, or use the compress tool afterward. - Going to social media? Convert and reframe in one go, for example "convert to MP4 and crop to 9:16 for TikTok". - Once the page has loaded you can work offline, since the conversion runs entirely in your browser. ## FAQ **Does my video get uploaded when I convert it?** No. Supercut decodes, converts, and exports entirely in your browser on your own device. Your footage is never uploaded. Only your text prompt is sent so the AI knows you want an MP4. **Will converting MOV to MP4 lose quality?** You should not see a meaningful drop. MOV and MP4 often hold the same H.264 or HEVC video, so converting is mostly a container change rather than a full rebuild, which keeps quality high. **Is it free to convert MOV to MP4?** You can try your first export free with no account. Paid plans unlock unlimited watermark-free exports and every tool, starting at 4.99/mo billed yearly (59.88/yr), 9.99/mo monthly, or 199 one-time lifetime. Cancel anytime. **Can I convert a large MOV file from my iPhone or camera?** Yes. Because the work happens on your device, there is no upload wait. Very large files use browser memory, so extremely big clips can be limited by your device, but typical phone and camera recordings convert fine. **Do I need to install anything?** No. Supercut runs in your browser at supercut.cc. There is no app or plugin to install to convert MOV to MP4. ## Do it in Supercut - [Convert video to MP4 online, universal format](https://www.supercut.cc/tools/convert-to-mp4) - [Compress a video online, smaller file, no upload](https://www.supercut.cc/tools/compress-video) - [Resize a video online, change resolution, no upload](https://www.supercut.cc/tools/resize-video-online) --- # How to blur faces in a video to protect privacy > Blur faces in a video to protect privacy without uploading your footage. Faces are detected on your device in the browser. Type a prompt, preview, and export. Source: https://www.supercut.cc/learn/how-to-blur-faces-in-a-video Published: 2026-06-22 Blurring faces is the simplest way to share footage without exposing the people in it. The catch with most online tools is that you upload your private clip to a stranger's server first, which defeats the purpose. Supercut detects and blurs faces on your device in the browser, so the footage you are trying to protect never leaves your machine. ## Why blur faces, and why on-device matters You might blur faces to publish street footage, post a clip filmed in public, share a classroom or workplace recording, or hand a video to a wider audience without identifying bystanders. In each case the people in frame did not agree to be recognizable, so removing their identity before you share is the responsible move. Here is the part most tools get wrong. To blur a face, software has to find the face first, and many web editors do that by uploading your video to their servers. The exact footage you are trying to keep private ends up copied onto someone else's computer. Supercut runs face detection in your browser, on your own device, so the sensitive clip stays with you the whole time. Your footage is never uploaded. Only your text prompt is sent, so the AI knows what edit to plan. ## How face blur works in Supercut You do not scrub a timeline or draw boxes by hand. You drop your clip into the browser and type what you want in plain English, like "blur the faces in this video." Supercut runs an on-device face detector over the clip, works out the region where faces appear, and then blurs that area using FFmpeg compiled to WebAssembly. If it cannot find a face, it falls back to a full-frame privacy blur so the people in the clip are still covered. Because everything runs in the browser, the work happens on your own processor. There is no upload queue and no account needed to try your first export. Once the page has loaded you can keep editing even if your connection drops. When the preview looks right, you export, and the blurred clip is the only file that gets saved out. ## Tips for clean, complete blurs Face blur works best on clear, well-lit, front-facing footage. Profiles, fast motion, heavy shadow, masks, and very small faces far in the background are harder to detect. If faces are scattered to opposite sides of the frame, or someone walks in and out, a single subject framed near the center is the most reliable case, so always watch the full preview before you export rather than spot-checking one frame. If a face is missed, you have options in the same session: increase the blur strength in your prompt, or fall back to a full-frame blur for guaranteed coverage. To remove identifying audio such as a spoken name, trim that section or replace the audio track. And if the clip is headed to a specific platform, blur first and then export with a TikTok, Reels, or Shorts preset so it is ready to post in one pass. ## Steps 1. **Open Supercut and drop in your clip.** Go to supercut.cc and drag your video into the browser. It loads straight into the editor and stays on your device. There is no upload, and no account is needed to try your first export. 2. **Type a plain-English prompt.** In the command box, type something like "blur the faces in this video." The AI reads only your text, not your footage, and plans the edit. Supercut then runs face detection on-device and applies the blur. 3. **Let it detect the faces.** Supercut runs an on-device detector over the clip to locate where faces appear, then blurs that region. If no face is found, it applies a full-frame privacy blur instead so no one is left uncovered. 4. **Preview the result.** Play the blurred clip in the preview panel and watch it all the way through. Check tricky moments like profiles, fast movement, and people entering or leaving the frame to confirm every face you care about is covered. 5. **Export the protected clip.** When it looks right, export. The blurred video is rendered on your device and saved locally. Your original footage never left your machine, and the file you share is the protected one. ## Tips - Watch the entire preview before exporting. Profiles, fast motion, and faces far in the background are the most likely to be missed. - Use clear, well-lit, front-facing footage when you can. Good lighting and direct angles give the detector the best chance of finding every face. - If a face is missed, raise the blur strength in your prompt or apply a full-frame blur for guaranteed coverage. - Faces are not the only giveaway. Trim or replace audio that names someone, and watch for tattoos, badges, name tags, and license plates. - Blur first, then apply a platform export preset (TikTok, Reels, Shorts) so the protected clip comes out sized and ready to post. ## FAQ **Is my video uploaded to blur the faces?** No. Face detection and blurring run on your device in the browser. That is the whole point: the sensitive footage you are trying to protect is never uploaded. Only your text prompt is sent so the AI knows what edit to plan. **Will it catch every single face?** It works best on clear, well-lit, front-facing footage and a single subject near the center of the frame. Profiles, heavy shadow, fast motion, masks, very small distant faces, and people spread to opposite sides of the frame are harder to cover, so always review the full preview before exporting. **What happens if no face is detected?** Supercut falls back to a full-frame privacy blur, so everyone in the clip is still obscured rather than left exposed. You can also ask for a full-frame blur directly when you want guaranteed coverage. **Can I blur faces for free?** You can try your first export free with no account. Unlimited watermark-free exports and every tool are part of a paid plan, which starts at 4.99 per month billed yearly (59.88 per year), 9.99 per month monthly, or 199 one time for lifetime access. You can cancel anytime. **Is blurring faces enough to fully anonymize a video?** Blurring faces removes the most obvious identifier, but it is not a guarantee of full anonymity. Voices, names spoken aloud, tattoos, clothing, badges, and license plates can still identify people, so review the whole clip and remove or obscure those details too. ## Do it in Supercut - [Blur faces in a video, private, on your device](https://www.supercut.cc/tools/blur-faces-in-video) - [Remove audio from a video, mute online, no upload](https://www.supercut.cc/tools/remove-audio) - [Crop a video for TikTok (9:16), face-tracking reframe](https://www.supercut.cc/tools/crop-video-for-tiktok) --- # How to make a GIF from a video > Turn any video clip into a shareable GIF right in your browser. Pick the moment, type a plain-English prompt, render, and download. Nothing uploads. Source: https://www.supercut.cc/learn/how-to-make-a-gif-from-a-video Published: 2026-06-23 A GIF is a short, silent, looping clip you can drop into a chat, a doc, or a post. Making one from a video means picking the right few seconds and converting that range. With Supercut you do it all in your browser: you type what you want in plain English, the AI plans the edit, and a deterministic engine renders the GIF on your own device. Your footage is never uploaded. ## What makes a good GIF Keep it short. A few seconds is usually enough: long enough to read the moment, short enough to loop cleanly. GIFs have no sound, so pick a moment that reads on its own. A tighter clip also keeps the file size down, which matters because GIF is an old format that gets heavy fast. If your loop feels too long or too large, trim it further or crop to just the part that matters. ## How Supercut converts a video to a GIF There is no timeline to scrub and no menus to hunt through. You describe the GIF you want, for example "turn 0:02 to 0:06 into a GIF." The AI reads your prompt plus the clip's metadata (duration, dimensions, filename) and plans the edit. A deterministic engine then maps that plan to the exact FFmpeg commands and runs them in your browser using WebAssembly. The only thing that leaves your device is the text of your prompt. The video itself stays local. ## Trim, crop, and size in the same prompt Because it is all plain English, you can stack the edit. Ask to trim to the exact range, crop to a square or vertical frame, or slow the clip down as part of the conversion. Supercut also converts the other way: it handles common formats including MP4, MOV, WebM, and GIF, so going from a GIF back to a video works too. If the result is too large to share, ask to compress it or shave a second off and render again. ## Steps 1. **Open your clip in the browser.** Open Supercut and add your video. It loads locally in your browser with no upload, so nothing is sent to a server. 2. **Type a plain-English prompt.** Say which moment to use, like "turn 0:02 to 0:06 into a GIF" or "make a GIF of the first 5 seconds." The AI plans the trim and the conversion for you. 3. **Review the result.** Check the rendered GIF. If it runs too long or feels too big, type a follow-up like "trim it tighter," "crop it square," or "compress it," and render again. 4. **Download and share.** Save the GIF to your device, ready to drop into chats, docs, or posts. The render happens on your machine, so your footage never leaves it. ## Tips - Keep it to a few seconds. Short loops read better and keep the file small. - GIFs are silent, so choose a moment that works without audio. - Crop to square or vertical first if the GIF is headed for a specific platform or chat. - If the file is too large to share, ask to compress it or trim a second off and render again. ## FAQ **Is my video uploaded to make a GIF?** No. The conversion runs in your browser using WebAssembly, so your video never leaves your device. Only the text of your prompt is sent so the AI knows what edit to plan. **Can I make a GIF from just part of a video?** Yes. Tell Supercut the exact range, like "turn 0:02 to 0:06 into a GIF," and it converts only that section. **What video formats can I turn into a GIF?** Supercut handles common formats including MP4, MOV, WebM, and GIF. You can also go the other way and convert a GIF back into a video. **Does it work offline?** Once the page has loaded, the editing and export run on your device, so you can keep working mid-edit even if your connection drops. **Is it free to make a GIF?** You can try your first export free with no account. Unlimited, watermark-free exports and every tool are included in a paid plan, starting at 4.99 a month billed yearly (59.88 a year), 9.99 monthly, or 199 one-time lifetime. ## Do it in Supercut - [Convert video to GIF, free, in your browser](https://www.supercut.cc/tools/video-to-gif) - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) - [Crop a video for TikTok (9:16), face-tracking reframe](https://www.supercut.cc/tools/crop-video-for-tiktok) - [Compress a video online, smaller file, no upload](https://www.supercut.cc/tools/compress-video) --- # How to remove background noise from a video > Remove background noise from a video right in your browser. Type a plain-English prompt, preview, and export. Footage never uploads. Steps, tips, and FAQ. Source: https://www.supercut.cc/learn/how-to-remove-background-noise-from-a-video Published: 2026-06-24 Background noise is the fastest way to make good footage feel amateur. Hiss, hum, fan rumble, and room tone bury the voice and pull attention from what is being said. With Supercut you clean up the audio by typing a plain-English prompt, and the whole process runs in your browser, so your recording is never uploaded. ## What background noise actually is Most unwanted sound falls into two buckets. The first is steady, broadband noise: tape hiss, electrical hum, air conditioning, computer fans, and general room tone. This kind sits under everything at a constant level, and it is the easiest to reduce because software can learn its profile and pull it down. The second bucket is sudden, irregular sound: a door slam, a cough, traffic, a notification ping. Steady noise responds well to cleanup. Irregular noise is harder, and the most reliable fix for a one-off sound is to trim that moment out instead of trying to erase it. ## How Supercut cleans audio in your browser Supercut is a prompt-based editor. You describe the edit in plain English, an AI plans it, and a deterministic engine maps that plan to FFmpeg operations that run locally through WebAssembly. For noise, that means the cleanup happens on your own device. Your footage and its audio are never sent to a server. Only your text prompt leaves the page, so the AI knows what you want done. The result is clearer speech with the constant background layer pulled down, exported as a normal video file. ## Get the cleanest result possible Cleanup goes further when you stack a few prompts in order. After reducing noise, ask Supercut to normalize the volume so the voice lands at a steady level once the background layer drops. If dead air at the start or end is where the hiss is most obvious, trim those seconds out. And if a single loud event ruins one stretch, cutting that slice is more dependable than fighting the sound itself. Clean, then normalize, then trim, all from plain-English prompts in a row. ## Steps 1. **Open Supercut and drop in your clip.** Go to Supercut in your browser and add the video with the noisy audio. It loads locally on your device. Nothing is uploaded. 2. **Type a plain-English prompt.** Ask for the cleanup in your own words, for example "clean up the audio and reduce background noise." The AI plans the edit and the engine applies it on your device. 3. **Preview the cleaned audio.** Play it back and listen for clearer speech with the hiss or hum pulled down underneath it. Want more? Follow up with another prompt like "normalize the volume" or "trim the first three seconds." 4. **Export your clip.** When it sounds right, export. The cleaned video is rendered locally and saved to your device, with your footage and audio never having left your browser. ## Tips - Steady noise like fans, hum, and hiss cleans up best. For a one-off sound like a cough or door slam, trimming that moment out is more reliable than trying to erase it. - Pair noise reduction with a "normalize the volume" prompt so the voice stays at a steady level after the background layer comes down. - Work offline if you like. Once the page has loaded, you can keep editing without a connection. - Record in the quietest space you can to begin with. Cleanup reduces noise, but it cannot fully replace a clean source. ## FAQ **Is my video uploaded when I remove the noise?** No. Audio cleanup runs in your browser through WebAssembly, so your footage and its audio stay on your device. Only your text prompt is sent, so the AI knows what edit to plan. **What kinds of background noise can it reduce?** Steady, constant noise is the best candidate: hiss, electrical hum, air conditioning, fan noise, and general room tone. Sudden one-off sounds are harder, and trimming that moment out is usually the better fix. **Will reducing noise make the voice sound worse?** Heavy noise reduction can thin out a voice, so Supercut aims for a clearer result without overprocessing. If the voice ends up uneven, follow up with a "normalize the volume" prompt to even it out. **Do I need to install anything or create an account?** No install, it runs in your browser. You can try your first export without an account. Unlimited watermark-free exports and every tool come with a paid plan, from 4.99 a month billed yearly, 9.99 monthly, or 199 one-time lifetime. **Can I remove the audio entirely instead of cleaning it?** Yes. If the audio is beyond saving, you can ask Supercut to mute or remove the audio, or replace the track with new audio, all from plain-English prompts. ## Do it in Supercut - [Clean up audio in a video, reduce background noise](https://www.supercut.cc/tools/remove-background-noise) - [Adjust video volume online, louder or quieter](https://www.supercut.cc/tools/adjust-video-volume) - [Remove audio from a video, mute online, no upload](https://www.supercut.cc/tools/remove-audio) --- # How to add music to a video or replace its audio > Add music to a video or swap its audio in your browser. Load a track, type a plain-English prompt, preview, and export. Nothing uploads, your files stay private. Source: https://www.supercut.cc/learn/how-to-add-music-to-a-video Published: 2026-06-25 Adding a soundtrack or swapping a clip's audio normally means a timeline editor and dragging tracks around. Supercut does it differently: you type what you want. You load the music as a second clip, name it in a plain-English prompt, and Supercut maps that audio onto your video. Everything runs in your browser, so your footage and your music never get uploaded. ## Two jobs: adding music vs. replacing audio Adding music and replacing audio are the same underlying move in Supercut: you point the video at a new audio source. If your clip is silent (B-roll, a screen recording, muted phone footage), pointing it at a music file simply gives it a soundtrack. If the clip already has sound you do not want, the same step swaps it: Supercut maps the new track on and the old audio is replaced. The swap replaces the track rather than layering a second one over the original, so when you want a clean music bed, mute or remove the original audio first, then bring in the music as the new track. ## How the audio swap works under the hood When you replace audio, Supercut copies your video stream verbatim and re-encodes only the audio. Your picture is untouched: no second-generation video compression, no visible quality loss. The deterministic engine maps your chosen audio onto the video and trims to the shorter of the two so you do not end up with stalled video or trailing silence. Because the work happens locally with WebAssembly, the only thing that ever leaves your device is the text of your prompt, never the video or the music. ## Getting the levels and timing right Plain-English follow-up prompts cover the common fixes. If a song is too loud over a voiceover, run a volume adjustment after the swap, like "lower the music a bit" or "raise the volume." To soften a hard musical entrance or ending, ask for a fade. If the track is longer than the clip, trim the video first so the audio lines up with the section you care about, then run the swap on the trimmed clip. Supercut maps the new audio to the shorter stream, so a trimmed video gives you precise control over where the music sits. ## Steps 1. **Open the editor and drop in your video.** Go to the Supercut editor and drop your video onto it. It loads straight into your browser as a clip. No account is needed to try your first export, and nothing is uploaded to a server. 2. **Load the music or audio clip too.** Drop the song, voiceover, or audio-bearing clip into the same editor. It loads as a second clip alongside your video, and you can reference it by name in a prompt. 3. **Type the plain-English prompt.** Tell Supercut to use the new audio. Reference your audio clip with @, for example "use audio from @music." On a silent clip this gives it a soundtrack; on a clip that already has sound this swaps the track. To clear the original first, say "remove the audio" before the swap. 4. **Preview the result.** Supercut runs the edit locally and plays it back. Check that the music starts where you expect and that voices and music sit at the right levels. Refine with follow-up prompts like "lower the music" or "add a 1 second fade out." 5. **Export and download.** When it sounds right, export. The video stream is copied as-is and only the audio is re-encoded, so picture quality stays intact. The finished file downloads to your device, having never left your browser. ## Tips - Reference your audio clip with @ in the prompt (for example "use audio from @song") so Supercut knows exactly which clip to map onto the video. - To fully replace existing sound, mute or remove the original audio first, then bring in your music as the new track. - If the music drowns out speech, follow the swap with a volume prompt like "lower the music," or normalize the audio for steadier loudness. - Add a short fade in and fade out so the soundtrack does not start or stop abruptly. ## FAQ **Does adding music upload my video or the song?** No. Supercut processes everything in your browser with WebAssembly. Your video and your audio clip never leave your device. Only the text of your prompt is sent, so the AI knows what edit to plan. **Will swapping the audio lower my video quality?** No. The video stream is copied verbatim and only the audio is re-encoded, so your picture stays at full quality. **Can I keep the original sound and add music on top?** The audio swap replaces the track rather than layering a second one. For a clean music bed, mute or remove the original audio first, then add the music. If you need to balance two sources, adjust volume with a follow-up prompt. **What audio and video formats can I use?** Common formats work, including MP4, MOV, and WebM for video and standard audio files for the soundtrack. You can also extract or convert audio as MP3 inside Supercut if you need a specific format. **Can I do this for free?** You can try your first export with no account. Unlimited watermark-free exports and every tool are part of the paid plan, which starts at 4.99 per month billed yearly (59.88 per year), with a 9.99 monthly option and a 199 one-time lifetime option.

Source: https://www.supercut.cc/learn/best-video-format-for-social-media Published: 2026-06-26 There is no single "best" format for every platform, but there is one safe default that plays everywhere: MP4 with H.264 video and AAC audio. From there, the only things that really change per platform are aspect ratio and resolution. This guide covers the settings that actually matter for TikTok, Instagram, and YouTube, and how to hit them in Supercut by typing a prompt, with nothing uploaded. ## The safe default: MP4 (H.264) + AAC If you remember one thing, use MP4 with the H.264 video codec and AAC audio. Every major platform accepts it, every phone and browser plays it, and it keeps files small without obvious quality loss. TikTok, Instagram, and YouTube all re-encode whatever you give them, so handing over a clean H.264 MP4 gives their compression the best possible starting point. You do not need HEVC, VP9, or ProRes for a social post, and those formats often cause upload or playback errors. If your clip came off a phone, screen recorder, or download as MOV, WebM, or MKV, convert it to MP4 first. ## Aspect ratio and resolution per platform Aspect ratio is what makes a clip feel native to a feed instead of letterboxed. For TikTok, Instagram Reels, and YouTube Shorts, export vertical 9:16 at 1080x1920 so it fills the phone screen. For a standard YouTube upload, use horizontal 16:9 at 1920x1080 (1080p), the sweet spot for sharpness versus file size. For a square Instagram feed post, 1:1 at 1080x1080 works well. Use 30fps as your default and reach for 60fps only when the source was actually shot at 60fps and the motion benefits, like sports or gameplay. Going above 1080p rarely helps for short clips, since the platforms compress hard on upload. ## Bitrate, audio, and file size You do not need to obsess over bitrate. For 1080p, roughly 8 to 12 Mbps looks clean and stays well under platform upload caps. Keep audio as AAC at about 128 to 256 kbps. If a file is still too large to upload, compress it rather than dropping resolution first. Compression lowers the bitrate and shrinks the file while keeping the same dimensions, which almost always looks better than shrinking the frame to a smaller, softer image. ## How Supercut handles the format for you In Supercut you never dig through a codec menu. You type the result you want in plain English, like "export for TikTok" or "convert to MP4 and crop to 9:16 at 1080p." The AI plans the edit and a deterministic engine maps it to the right FFmpeg settings. Everything runs in your browser through WebAssembly, so your footage is never uploaded; only the text of your prompt is sent so the AI knows what to do. Built-in platform presets for TikTok, Reels, Shorts, Twitter, and Discord set the aspect ratio and encoding in a single step. Your first export is free to try with no account; unlimited watermark-free exports start at 4.99 per month billed yearly. ## Steps 1. **Drop your clip into the browser.** Open the Supercut editor and drag your video onto the page. It loads locally, with no upload and no account needed to try your first export. 2. **Type the platform you are exporting for.** Describe it plainly, like "export for TikTok" or "convert to MP4, crop to 9:16, 1080p." Supercut plans the format, aspect ratio, and resolution from your words. 3. **Run it and check the output.** The edit runs on your device and you get the result back in the page. Confirm the framing looks right vertical or horizontal before you save. 4. **Save and upload.** Download the finished MP4 to your device, then upload it to the platform. The whole process ran in your browser, so your original footage never left your machine. ## Tips - When in doubt, export MP4 (H.264) at 1080p. It is the most widely accepted combination across TikTok, Instagram, and YouTube. - Match the aspect ratio to the surface: 9:16 for TikTok, Reels, and Shorts; 16:9 for standard YouTube; 1:1 for a square feed post. - If a file is too big to upload, compress it instead of dropping resolution. You keep the same frame size with a smaller file. - Skip exporting above 1080p for short social clips. Platforms re-compress on upload, so the extra size rarely shows as visible quality. ## FAQ **What is the best video format for social media?** MP4 with the H.264 video codec and AAC audio. TikTok, Instagram, and YouTube all accept it, it plays on every device, and it gives the platforms a clean file to re-encode. Use it as your default and change only the aspect ratio and resolution per platform. **What resolution should I use for TikTok and Reels?** Vertical 9:16 at 1080x1920 is the standard for TikTok, Instagram Reels, and YouTube Shorts. It fills the phone screen with no black bars. Going higher than 1080p rarely helps, because the platforms compress after upload. **Do I need to upload my video to convert or reframe it?** No. Supercut runs entirely in your browser using WebAssembly (FFmpeg.wasm), so your footage never leaves your device. Only the text of your prompt is sent so the AI knows what edit to plan. **My file is too large to upload. What should I do?** Compress it. Compression lowers the bitrate and shrinks the file while keeping the same dimensions, which usually looks better than reducing the resolution. In Supercut you can just say "compress this for upload." **Should I export at 60fps?** Only if your source was actually recorded at 60fps and the motion benefits, like fast action or gaming. For most social clips, 30fps is a fine default and keeps file sizes lower. ## Do it in Supercut - [Convert video to MP4 online, universal format](https://www.supercut.cc/tools/convert-to-mp4) - [Crop a video for TikTok (9:16), face-tracking reframe](https://www.supercut.cc/tools/crop-video-for-tiktok) - [Compress a video online, smaller file, no upload](https://www.supercut.cc/tools/compress-video) --- # Video aspect ratios explained: 9:16, 1:1, and 16:9, and when to use each > A plain guide to video aspect ratios. Learn what 9:16, 1:1, and 16:9 mean, which platform wants which, and how to reframe a clip in your browser. Source: https://www.supercut.cc/learn/video-aspect-ratios-explained Published: 2026-06-27 Aspect ratio is the shape of your video frame: how wide it is compared to how tall. Get it right and your clip fills the screen on the platform you are posting to. Get it wrong and you end up with black bars, awkward crops, or a subject pushed out of frame. This guide explains what 9:16, 1:1, and 16:9 mean, when to use each, and how to switch between them in Supercut by typing a prompt, with nothing uploaded. ## What aspect ratio actually means Aspect ratio is written as width:height. A 16:9 frame is 16 units wide for every 9 units tall, so it is a wide rectangle. A 9:16 frame flips that to a tall rectangle, and 1:1 is a perfect square. The numbers are a ratio, not a resolution: 1920x1080 and 1280x720 are both 16:9 because the proportions match. When your video's shape does not match the space a platform gives it, the player either adds bars to pad the gap or crops the edges to fill it. Choosing the right ratio up front keeps the frame full and your subject where you want it. ## 9:16, 1:1, and 16:9: when to use each Use 9:16 (vertical, tall) for full-screen mobile feeds. TikTok, Instagram Reels, and YouTube Shorts are all built around it. It fills a phone held upright and gives you the most screen space where most people watch. Use 16:9 (wide, landscape) for YouTube, desktop viewing, presentations, and most TVs. It suits interviews, tutorials, gameplay, and anything filmed on a normal camera held sideways. Use 1:1 (square) as the safe middle ground for in-feed posts on Instagram and Facebook and for embeds where you do not control the orientation. A square takes more vertical space in a scrolling feed than a wide clip without committing to a full vertical crop. ## Cropping vs resizing: two different fixes There are two ways to change a frame's shape, and they do different things. Cropping (also called reframing) cuts away part of the picture so the subject fits the new ratio, for example taking a wide 16:9 clip and reframing it to 9:16 for Reels. You keep full-screen impact but lose the edges, so the subject can drift out of frame if the camera moves. Resizing fits the whole picture inside the new frame and pads the rest, adding bars on the sides (pillarbox) or top and bottom (letterbox). The rule of thumb: crop or reframe when you want the subject to fill the screen, and resize with padding when you need to keep everything in shot. Supercut can do both, and its smart reframe uses on-device face tracking to keep the subject centered as they move. ## How Supercut handles aspect ratio In Supercut you do not scrub a timeline or drag crop handles. You drop a clip into the editor and type what you want in plain English. An AI plans the edit, then a deterministic engine maps your request to the exact frame operation. Everything decodes, reframes, and exports in your browser through WebAssembly, so your footage is never uploaded. The only thing sent over the network is your text prompt, so the tool knows the target shape. Supercut also ships platform export presets for TikTok, Reels, Shorts, Twitter, and Discord, so you can ask for a format by name instead of remembering the numbers. ## Steps 1. **Drop your clip in the browser.** Open the Supercut editor and drag in your video. It loads straight into your browser. Nothing uploads, and you can try your first export without an account. 2. **Type the ratio you want.** Describe the target shape in plain English, like "reframe this to 9:16 for TikTok," "crop to a 1:1 square," or "resize to 16:9 with padding." For moving subjects, ask for smart reframe so on-device face tracking keeps them centered. 3. **Review the result.** The reframe runs on your device and shows you the output. Check that the subject sits where you want and nothing important got cut off. If it is too tight, ask to adjust the crop or switch to a resize with padding. 4. **Export and download.** Export the reframed clip and download it. The whole edit happened in your browser, so your footage never left your machine. Your first export is free to try. A paid plan unlocks unlimited watermark-free exports, from 4.99/mo billed yearly, 9.99/mo monthly, or 199 one-time lifetime. ## Tips - Shoot with headroom and keep your subject near center so a later crop to 9:16 does not clip faces. - Match the ratio to where you are posting: 9:16 for TikTok, Reels, and Shorts, 16:9 for YouTube, 1:1 for in-feed posts. - Use smart reframe for any clip where the subject moves, so face tracking keeps them in frame instead of a fixed crop. - Reframe before adding captions so text is placed against the final frame, not the old one. ## FAQ **What is the difference between 9:16 and 16:9?** They are the same ratio flipped. 16:9 is wide (landscape), used for YouTube and desktop. 9:16 is tall (vertical), used for TikTok, Reels, and Shorts. Switching between them means cropping away part of the picture or padding it to fit the new shape. **Which aspect ratio is best for TikTok, Reels, and Shorts?** 9:16 vertical. It fills a phone held upright and gives you the full screen on the feeds where most people watch. Supercut has presets for each platform, so you can ask to reframe for TikTok, Reels, or Shorts by name. **Will I lose quality when I change the aspect ratio?** Changing the shape does not degrade the picture by itself. You only lose the edges that get cropped away when you crop. You choose the export settings, so you stay in control of the final resolution and file size. **Does my video get uploaded when I reframe it?** No. Supercut decodes, reframes, and exports entirely in your browser using WebAssembly. Your footage never leaves your device. Only the text of your prompt is sent so the AI knows which ratio you want. **How do I avoid cutting off the subject when going vertical?** Use smart reframe, which tracks faces on-device and keeps the subject centered as they move. Filming with headroom and a centered subject also gives the crop more room to work with. ## Do it in Supercut - [Crop a video for TikTok (9:16), face-tracking reframe](https://www.supercut.cc/tools/crop-video-for-tiktok) - [Resize a video online, change resolution, no upload](https://www.supercut.cc/tools/resize-video-online) - [TikTok video editor online, 9:16, captions, no upload](https://www.supercut.cc/tools/tiktok-video-editor) --- # How to edit video without uploading it > Most online editors upload your footage to their servers.

Source: https://www.supercut.cc/learn/how-to-edit-video-without-uploading Published: 2026-06-28 Most "online" video editors quietly upload your footage to their servers to process it. If your video is sensitive, unreleased, or simply yours, that is a problem. Here is how to edit entirely in your browser, so the file never leaves your device. ## Why "online" usually means "uploaded" Cloud editors do the heavy lifting on their servers, so the first thing they do is upload your file. That means your footage sits on someone else's machine, subject to their retention, access, and breach risk. For legal, medical, journalistic, or pre-launch content, that single step can be a dealbreaker. ## The alternative: process on your own device Supercut runs the whole editing pipeline (decode, edit, export) in your browser using WebAssembly. Your footage stays on your machine the entire time. The only thing that goes over the network is the short text prompt you type, so the AI knows which edit to plan. There is no file upload. ## How to verify nothing is uploaded You do not have to take our word for it. Load the page, then open your browser developer tools and switch the network to offline, or simply unplug. Run an edit and export it. It still works, because the processing is local. A cloud editor would stall the moment it lost the connection. ## Steps 1. **Open the editor in your browser.** Go to the Supercut editor. There is nothing to install and no account needed to try your first export. 2. **Drop in your clip.** Add your video. It loads straight into the browser tab and stays on your device. Nothing uploads. 3. **Describe the edit in plain English.** Type what you want, like trim to the first 30 seconds, blur the faces, or add captions. The AI plans it and a local engine runs it. 4. **Preview and export.** Check the result and download. Your footage never left your machine, only the text of your prompt was ever sent. ## Tips - For maximum certainty, load the page, go offline, then edit and export. - Sensitive faces or details? Blur them before you share the file anywhere. - Very large 4K files use a lot of memory, since everything runs on your device. ## FAQ **Can you really edit video without uploading it?** Yes. Supercut processes video in your browser with WebAssembly, so the file stays on your device. Only your text prompt is sent so the AI knows what to do. **Is a browser editor safe for sensitive footage?** Because nothing is uploaded, there is no server copy of your footage to leak or subpoena. It is a strong fit for legal, medical, journalistic, and unreleased material. **Does it work offline?** Once the page has loaded, yes. You can switch to offline and still finish an edit, which is also the simplest way to prove nothing is being uploaded. **What is the catch?** Processing uses your own device, so very large files depend on your machine's memory. For most clips this is a non-issue, and the privacy tradeoff is worth it. ## Do it in Supercut - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) - [Blur faces in a video, private, on your device](https://www.supercut.cc/tools/blur-faces-in-video) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) --- # How to record your screen > Record your screen, microphone, and camera, then land on an editor that has already framed the result. Everything runs on your device and nothing uploads. Source: https://www.supercut.cc/learn/how-to-record-your-screen Published: 2026-08-01 Recording your screen should be three decisions, not thirty: what to capture, whether your voice comes along, and whether your face does. Supercut records the screen, your microphone, and your camera as three separate tracks, then drops the take onto a timeline that has already framed and styled it. All of it runs on your own machine, so nothing is uploaded, and exports carry no watermark. ## Decide what to capture before you hit record There are three shapes of capture and they are not interchangeable. A whole screen shows everything, including notifications, your tab strip, and anything you forgot was open. A single window shows one app and keeps the rest of your desktop out of it, which is usually the right call for a walkthrough. A browser tab is the tightest of all, and in Chrome it is also the option that can bring the tab's own audio along. Then decide about sound and face. Your microphone is what you say. System audio is what the machine plays, which matters when the product you are showing makes noise. Your camera is optional and can be added or dropped later, because Supercut keeps it as its own layer rather than baking it into the picture. Choosing all this up front is what saves you the second take. ## Browser or desktop app: what actually changes The browser recorder works in Chrome, Edge, Brave, and Arc with nothing to install. You pick a screen, window, or tab through the browser's own dialog, and in Chrome you can bring audio from a shared tab. What the browser cannot do is watch your cursor outside the page, so there are no automatic zooms and the pointer is part of the recorded picture. The desktop app can see more of the machine. It captures the audio playing on your computer, on both macOS and Windows, and it samples your cursor about sixty times a second while you record. That cursor track is what makes automatic zooms possible: where the pointer settles becomes a candidate for a push-in. On macOS it also records clicks, so a click counts even when the cursor keeps moving, and when you capture a whole display the pointer is left out of the video and redrawn afterwards, which is what lets you restyle it. On Windows, and on a macOS window capture, the pointer is part of the recorded frames. ## Three tracks, a count-in, and a pause that behaves Screen, microphone, and camera are recorded separately. That is the reason the camera bubble stays movable, resizable, and removable after the take, instead of being welded into the picture the moment you stop. It also means you can mute or delete a track later without touching the others. A count-in of three or five seconds gives you a moment to get set, and it runs after you pick the source rather than before it. Pause and resume as often as you need: the paused time is folded out of the final length, so the recording does not carry a gap where you stepped away, and the cursor track is retimed to match so the zooms still land where you were pointing. ## What happens when you stop The take lands on the Studio timeline already framed: sitting on a backdrop with padding, rounded corners, and a shadow, so it looks composed rather than like a raw desktop capture. The backdrops are drawn in the page with CSS and SVG rather than loaded as images, which is why the preview and the exported file look the same. From there it is an ordinary edit. Trim the dead air, add or adjust zooms, caption it with the on-device transcriber, resize the camera bubble or drop it, then export an mp4 or a GIF. Nothing has been uploaded at any point, so an unreleased product, an internal dashboard, or a customer record on screen stays on the machine that recorded it. ## Steps 1. **Open the editor and start the recorder.** Open Supercut, switch to the Editor tab, and start a recording. Nothing installs in the browser, and the desktop app for Mac and Windows does the same job with system audio and cursor tracking added. 2. **Pick a screen, a window, or a tab.** Choose the narrowest thing that shows what you mean. A single window keeps your desktop, your notifications, and your tab strip out of the recording without you having to tidy them. 3. **Add your microphone and camera.** Turn on the microphone if you are narrating and the camera if you want a bubble. Set the capture quality and a count-in of three or five seconds while you are here. 4. **Record, and pause when you need to.** The count-in runs, then you are rolling. Pause whenever you need to reset something on screen and resume when you are ready; the paused time is left out of the final length. 5. **Polish and export.** Stop, and the take appears on the timeline already framed on a backdrop. Trim, add zooms, caption it, then export an mp4 or a GIF. The whole thing ran on your device. ## Tips - Silence notifications and close the tabs you would not screenshot. A screen recording captures everything the screen shows, including a message that arrives mid-take. - Record a window rather than a whole display when only one app matters. It is the fastest way to keep the rest of your desktop out of the video. - Capture at a higher quality than you plan to publish if you intend to zoom, because a zoom crops into the pixels you actually recorded. - Use the count-in instead of scrambling. Three seconds is enough to get your hands and your first sentence ready. - Pause rather than restarting. A pause costs nothing in the final length, and a restart costs you the take you already had. ## FAQ **Do I need to install anything to record my screen?** No. The browser recorder works in Chrome, Edge, Brave, and Arc with nothing to install. The desktop app for Mac and Windows adds system audio and cursor tracking, which is what makes automatic zooms possible. **Can it record computer audio as well as my microphone?** In the browser, Chrome can capture the audio of a shared tab. The desktop app records the audio playing on the whole machine, on both macOS and Windows, alongside your microphone. **Is my screen recording uploaded anywhere?** No. Recording, editing, and export all happen on your device. There is no server copy and no share link, because the file never leaves your machine. That is the point for anything showing customer data, internal tools, or an unreleased product. **Can I record my screen and my camera at the same time?** Yes. The screen, your microphone, and your camera are recorded as three separate tracks, and the camera is never baked into the picture, so you can move, resize, or remove the bubble after the take. **Is there a watermark or a time limit?** No watermark. Length is bounded by your own disk and memory rather than by a plan tier, though long recordings of large screens are heavier on both. You can try your first export with no account, and a paid plan unlocks unlimited exports and every tool, from 4.99 per month billed yearly (59.88 per year), 9.99 monthly, or 199 one-time lifetime. ## Do it in Supercut - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) --- # How to add zoom effects to a screen recording > Add push-in zooms so viewers can see what you clicked. The desktop app places them from your cursor; in the browser you place them yourself. Nothing uploads. Source: https://www.supercut.cc/learn/how-to-add-zoom-effects-to-a-screen-recording Published: 2026-08-02 A screen recording is a big picture shown small. A 1440p desktop scaled into a feed or an email is a wall of tiny text, and the one field you are talking about is a few pixels tall. A zoom fixes that: it is the video equivalent of pointing at the screen. Supercut can generate zooms from your cursor on the desktop app, and you can place, retime, or delete every one of them by hand. ## Why screen recordings need zooms more than other footage Camera footage is composed for its frame. A screen recording is not: it is a whole desktop, captured at whatever size your monitor happens to be, then shrunk to fit wherever the video is watched. Menu labels, form fields, and inline validation all survive that shrink badly. A zoom does two jobs at once. It makes the detail legible, and it tells the viewer where to look, which is the part people underrate. Without one, a viewer spends the first two seconds of every step scanning the frame for whatever changed. With one, the answer is already centered. That is why a demo with four well-placed zooms reads as clearer than the same demo at the same length with none. ## Automatic zooms, and where they come from The desktop app samples your cursor position about sixty times a second while you record. When you stop the take, Supercut looks for the moments where the pointer settled, merges the ones that sit close together in time and space, and turns the strongest of them into push-ins with a lead in and a lead out, so the zoom starts a beat before you act rather than after. On macOS it also records clicks, so a click on the move counts as a reason to zoom even when the cursor never paused. That is how people actually demo things: click and keep going. Every generated zoom is an ordinary editable zoom afterwards, so you can retime it, move its target, or delete it. In the browser there is no way to watch the cursor outside the page, so there are no automatic zooms there and you place them yourself. ## Placing and editing a zoom by hand Select the recording on the timeline and the inspector shows its demo settings, including the list of zooms. Add one, and it starts where the last one ended; set its start and end and where in the frame it should push into. The timings are measured into the source recording rather than into the timeline, which is the detail that makes them survivable. Trim the front of the clip, split it, or move it, and the zoom stays attached to the moment it was pointing at. That is also why a saved look preset carries your backdrop, padding, corners, and cursor style across projects but does not carry zooms: zooms belong to the footage that produced them, and pasting them onto other footage puts push-ins over whatever happens to be at those frames. ## Making zooms feel deliberate instead of restless Three habits separate a zoom that helps from one that makes viewers seasick. Hold long enough to read: a push-in that arrives and leaves inside a second is just a flinch. Zoom less often than you think, because when everything is emphasized nothing is; four in a two-minute demo is usually plenty. And stay inside your captured resolution, since a zoom crops into real pixels and a 2x push-in on a 720p capture looks exactly like a 2x push-in on a 720p capture. Watch the camera bubble too. A zoom exists to point at something, and a bubble parked over that something defeats it, so pull the bubble back or hide it for the length of the zoom. ## Steps 1. **Record or open the screen capture.** Record in Supercut, or drop an existing screen recording onto the timeline. Either way the file stays on your device. 2. **Select the recording on the timeline.** Click the screen clip. The inspector on the right shows its demo settings: backdrop, padding, corners, cursor, camera, and the list of zooms. 3. **Let the desktop app place its zooms, or add your own.** If you recorded on the desktop app, zooms are already there from your cursor and clicks. In the browser, add one and it starts where the previous zoom ended. 4. **Retime, retarget, and delete.** Set each zoom's start and end and where it pushes into. Delete the ones that do not earn their place; fewer, longer zooms almost always read better than many short ones. 5. **Preview, then export.** Play it back at the size people will actually watch it. When the detail is legible and the motion feels intentional, export an mp4 or a GIF, rendered on your machine. ## Tips - Hold a zoom long enough to read what it is pointing at. A push-in shorter than about a second reads as a glitch rather than emphasis. - Record at a higher capture quality than you publish at, because a zoom crops into the pixels you recorded rather than inventing new ones. - Zoom for the small stuff: form fields, menu items, inline errors. Full-screen layout changes are already legible. - Hide or pull back the camera bubble during a zoom so it is not sitting on the thing you are pointing at. - Trim first if you like, since zoom times are measured into the source recording and survive trims and splits. ## FAQ **Can Supercut zoom in automatically where I click?** On the desktop app, yes. It samples your cursor while you record and turns the moments where the pointer settles, and on macOS the moments where you click, into push-ins. Every one of them is editable or deletable afterwards. In the browser there is no way to track the cursor outside the page, so you place zooms yourself. **How do I add a zoom in the browser version?** Select the recording on the timeline, open its demo settings in the inspector, and add a zoom. Set its start, its end, and the point in the frame it should push into. You can add as many as the clip needs. **Will my zooms survive trimming the clip?** Yes. Zoom times are measured into the source recording rather than the timeline, so trimming, splitting, or moving the clip keeps each zoom attached to the moment it was pointing at. **Does zooming reduce quality?** A zoom crops into the pixels you captured, so a deep push-in on a low-resolution capture will look soft. Record at a higher quality than you plan to publish and keep the zoom depth modest, and it stays sharp. **Can I save my zooms as a preset for the next recording?** Look presets carry the backdrop, padding, corners, cursor style, and camera treatment across projects, but not the zooms. Zooms belong to the recording that produced them, so copying them onto different footage would put push-ins over whatever happened to be at those frames. ## Do it in Supercut - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Picture-in-picture video, overlay a second clip](https://www.supercut.cc/tools/picture-in-picture) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) --- # How to record a product demo video > Plan, record, and polish a product demo: what to show, how to set up the capture, where zooms belong, and how to export. Your screen never leaves your device. Source: https://www.supercut.cc/learn/how-to-record-a-product-demo Published: 2026-08-03 Most product demos fail for the same two reasons: they show the tour instead of the point, and they look like a raw desktop capture. Both are fixable before you press record. This is the whole run, from deciding what the demo has to prove to exporting a file you can attach to an email, and none of it involves uploading your screen to anyone. ## Decide what the demo has to prove A demo is an argument, not a feature tour. Pick the one job your viewer is trying to get done and show that job completed, start to finish. Everything that does not serve it, the settings page, the integrations list, the thing you are personally proud of, comes out. Write the beats before you record: the problem in one line, the two or three steps that solve it, and the result. Say the numbers out loud so you know how long each beat runs. Two minutes is a generous ceiling for a demo that lives on a landing page or in an inbox, and most good ones are shorter. Then set up the data you will be showing, ideally in a demo account with names and figures you are happy to have on screen forever, because a screen recording keeps whatever was on screen. ## Set the capture up so you do not need a second take Record a single window rather than a whole display when you can. It excludes your desktop, your tab strip, and everything you did not tidy up, without you having to tidy up. Then silence notifications, close the tabs you would not screenshot, and check the corners of the frame for anything you missed. Turn on the microphone if you are narrating, and system audio if the product itself makes sound, which the desktop app captures on macOS and Windows. The camera is a judgment call, and a cheap one, because Supercut records it as its own track: you can move, shrink, or delete the bubble after the take rather than committing now. Set a capture quality a step above where you will publish if you plan to zoom, and give yourself a count-in so your first sentence is not a scramble. ## Record in takes, not in one perfect run The pressure to nail a demo in one continuous pass is what makes people stiff. You do not need it. Pause when you reach the end of a beat, reset the app to where the next beat starts, and resume. The paused time is folded out of the final length, so the recording behaves as if you never stopped, and the cursor track is retimed to match so automatic zooms still land on the right moments. If you fumble a sentence, pause, take it again from the top of that beat, and cut the bad one later. The finished length comes from the recorder's own clock rather than from the container, so a paused, resumed, restarted take still reports a length you can trust when you start trimming. ## Polish, then export something you can send The take lands on the timeline already sitting on a backdrop with padding, rounded corners, and a shadow, so the first thing that usually made a demo look raw is handled. Cut the dead air, especially loading spinners and the seconds where you were finding your next word. Add zooms at the moments where a viewer needs to see a small thing, and let a zoom hold long enough to read. Then add captions, because demos get watched on mute in inboxes and Slack threads, and Supercut transcribes on your device rather than sending your audio anywhere. Decide the camera bubble question now: keep it small and out of the way, or drop it entirely. Export an mp4 for a landing page or an email, or a GIF for a doc or an issue thread. Nothing was uploaded at any point, which is what makes this workable for a product that has not shipped yet. ## Steps 1. **Script the beats and prepare the data.** Write the problem, the two or three steps that solve it, and the result. Set up a demo account with figures and names you are happy to show, since the recording keeps whatever is on screen. 2. **Set up the capture.** Pick the window rather than the whole screen, silence notifications, and close stray tabs. Turn on the microphone, add system audio if the product makes sound, and set a count-in. 3. **Record beat by beat.** Run each beat, then pause while you reset for the next one. The paused time is folded out of the final length, so pausing costs you nothing and saves you the perfect-run pressure. 4. **Trim and add zooms.** Cut loading spinners and hesitations. Add a zoom where the viewer needs to see something small, and let it hold long enough to read. On the desktop app, zooms from your cursor are already there to edit. 5. **Caption and export.** Add captions for the people watching on mute, then export an mp4 for a page or an email, or a GIF for a doc. It renders on your machine, with no watermark. ## Tips - Show one job done end to end. A feature tour is a longer video that convinces fewer people. - Use a demo account with data you would be comfortable seeing on a landing page a year from now. - Record the window, not the display, and your tab strip and notifications never become a problem. - Decide the camera bubble after the take, not before. It is recorded as its own layer, so keeping it is not a commitment. - Export a GIF of the single best twelve seconds for docs, changelogs, and issue threads, and keep the mp4 for the page. ## FAQ **How long should a product demo video be?** Aim under two minutes for a demo on a landing page or in an email, and shorter if the job you are showing is simple. Length is not the goal; showing one job completed, without a tour of everything else, is. **Do I need a camera on screen for a product demo?** Not necessarily. A face helps a sales or founder demo feel personal and adds nothing to a support walkthrough. Supercut records the camera as its own track, so you can size the bubble down, hide it during zooms, or delete it after the take. **How do I record the product's own audio, not just my voice?** The desktop app captures the audio playing on your machine on both macOS and Windows. In the browser, Chrome can capture the audio of a shared tab, which covers a web app demo. **Is it safe to demo an unreleased product this way?** The recording, the editing, and the export all happen on your device, and there is no upload and no share link, so no copy of your screen exists on anyone else's server. That is the practical reason to record locally when the product has not shipped. **What should I export for a landing page versus a Slack thread?** An mp4 for a landing page, an email, or anywhere with a real player. A GIF of the best few seconds for docs, changelogs, and chat threads, where autoplay and no sound are the norm. Supercut exports both from the same timeline. ## Do it in Supercut - [Screen recorder with a built-in editor, no upload](https://www.supercut.cc/tools/screen-recorder) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) - [Convert video to GIF, free, in your browser](https://www.supercut.cc/tools/video-to-gif) - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) --- # What is a supercut? > A supercut is a video montage that stitches together every instance of a repeated word, gesture, or scene. Learn the supercut definition, its history, and how to make one. Source: https://www.supercut.cc/learn/what-is-a-supercut Published: 2026-08-11 A supercut is a video montage assembled from many short clips that share something in common: a repeated word or phrase, a recurring gesture, a camera move, a theme. The clips are stitched together back to back, and the accumulation is the point. Watching every time a character says a specific word, or every instance of the same visual gag, creates something the individual clips cannot do on their own. ## Supercut definition A supercut is an edited video that collects every occurrence of a specific element from a film, television show, or other video source, and plays them in sequence. The element can be anything: a word, a phrase, a facial expression, a plot device, a camera angle. The term was coined in 2008 by Andy Baio on his blog Waxy.org, where he used it to describe a growing genre of fan-made compilation videos on YouTube. The word is now used broadly enough that naming a video editor after it, as this one is, makes sense: the tool that helps you cut quickly and the genre that is built from rapid cuts share the same instinct. ## Where the word came from Before supercut, these compilations were called mashups, megamixes, or simply compilation videos. Baio named the genre after noticing that a particular style had emerged on YouTube: fast, obsessive, built around a single repeated element rather than a narrative. Early examples included every instance of Jack Bauer saying damn it across seasons of 24, every time someone says the title of the movie in the movie, and every Klingon word spoken across Star Trek. The form spread to sports, politics, and advertising, and the word entered common use. Today, a supercut can be a serious piece of criticism, a comedy bit, or a fan tribute, and the technique has been adopted by professional editors and marketers as well as hobbyists. ## What makes a good one The best supercuts have a thesis. Every time a news anchor says a phrase, every time a politician makes the same gesture, every time a film repeats a shot: the compilation reveals a pattern the individual clips hide. Without a clear organizing principle, a supercut is just a playlist. The editing matters too. Tight cuts with no gaps between clips create momentum. Adding a brief beat of silence or a consistent transition can give the compilation rhythm without slowing it down. The length should match the material: thirty clips in ninety seconds hits harder than the same thirty spread across five minutes. ## How to make a supercut The traditional way is slow. You watch the source material, note every timestamp where your target element appears, trim each one out, and join the pieces. Supercut the editor was built to make this faster. Drop your clips into the browser, type what you want in plain English, and the tool handles the cuts on your device. You can trim individual clips, chain them together, add captions, and export, all without uploading anything. For a supercut built around a spoken word, the transcript-based editing lets you find and cut by reading the words rather than scrubbing a timeline. ## Steps 1. **Pick your repeating element.** Decide what binds the clips together: a word, a gesture, a shot type, a theme. The more specific the element, the tighter the supercut. 2. **Gather the clips.** Collect every instance you can find. Drop them into Supercut in your browser. Nothing uploads, so unreleased or sensitive material stays on your machine. 3. **Trim each clip to the moment.** Cut each clip down to the exact moment the element appears. Type a prompt or use the timeline. Tight trims make a tighter supercut. 4. **Chain them together.** Join the trimmed clips back to back. Add captions if the supercut needs context, then export in the format your platform wants. ## Tips - Keep clips under three seconds each. The compilation should feel relentless. - Order matters. Chronological, alphabetical, or by increasing absurdity all work. Random does not. - If the supercut is built around a word, use the transcript to find every instance instead of scrubbing manually. - Sound design separates a forgettable compilation from one that gets shared. Consider whether to keep, mute, or score the audio. ## FAQ **What does supercut mean?** A supercut is a video compilation that stitches together every instance of a repeated element, like a word, gesture, or scene, from a single source or across multiple sources. The term was coined in 2008 by Andy Baio. **Where did the word supercut come from?** Andy Baio coined the term on his blog Waxy.org in 2008 to describe a genre of fan-made YouTube compilations that collected every occurrence of a specific repeated element from a film or TV show. **Is a supercut the same as a compilation video?** A supercut is a specific type of compilation built around a single repeating element. A general compilation video might cover many topics or highlights, while a supercut is obsessive about one thing. **Can I make a supercut in a browser?** Yes. Supercut the editor runs entirely in your browser, so you can trim clips, join them, add captions, and export without uploading anything. The transcript-based editing makes it easy to find every instance of a word. ## Do it in Supercut - [Trim a video online, free, private, no upload](https://www.supercut.cc/tools/trim-video) - [Combine videos online, merge clips, no upload](https://www.supercut.cc/tools/combine-videos) - [Add captions to a video, automatically, on your device](https://www.supercut.cc/tools/add-captions) --- # The Supercut blog > 10 editorial posts on privacy, workflow and the tool landscape.

Nothing sours a free video editor faster than finishing an edit and discovering the export has a logo stamped across it. The good news is that several genuinely capable editors let you export clean footage without paying. This list only includes tools where a normal free export comes out without a watermark, and it is honest about the catches, because every free tool has one somewhere. ## How this list was chosen A watermark is the exporting tool stamping its logo onto your video, usually to push you toward a paid plan. Plenty of "free" editors let you do the whole edit and only reveal the watermark, or an export paywall, at the last step. That pattern wastes your time, so it disqualifies a tool here. Every editor below meets three tests: a standard free export produces a clean file with no logo, the free tier includes real editing (not a crippled demo), and the tool is something we would actually recommend to a friend for at least one kind of job. For each one you also get the honest catch, because free always costs something, whether that is a learning curve, a feature wall, or your footage traveling to someone else’s server. ## Supercut: private, prompt-based, in your browser Supercut is a different kind of editor: instead of learning a timeline, you type what you want in plain English, like "trim the first 10 seconds, crop to 9:16, and add captions." An AI plans the edit, a deterministic engine maps it to exact FFmpeg commands, and everything runs locally in your browser through WebAssembly. Your footage is never uploaded, and exports never carry a Supercut logo. The honest catch: the free tier is a trial, not unlimited. You can try your first export free with no account, and paid plans unlock unlimited watermark-free exports and every tool, starting at 4.99 per month billed yearly (59.88 per year), 9.99 monthly, or 199 one-time for lifetime access. Best for quick social edits, captions, format conversion, and any footage you do not want sitting on a server. ## CapCut: the social media powerhouse CapCut is free, runs on phone, desktop, and web, and its standard exports do not carry a watermark. Its template library, effects, and auto-captions are why it dominates short-form editing. If you make TikToks or Reels and want trendy effects with zero cost, it is the obvious pick. The honest catch: CapCut is owned by ByteDance, TikTok’s parent company, an account is pushed hard, and cloud features involve uploading your footage. Over the last couple of years a steady stream of features has migrated behind the Pro subscription, and some templates append a removable branded outro. Its legal status in the US has also shifted repeatedly, so its availability is worth checking. If any of that matters to you, read our full look at CapCut’s privacy picture linked below. ## DaVinci Resolve: professional grade, genuinely free DaVinci Resolve is the outlier on this list: a full professional editing, color grading, and audio suite whose free desktop version has no watermark and no export time limit. Hollywood colorists use the paid Studio edition, but the free one is more editor than most people will ever exhaust. The honest catch: it is heavy. The download is large, it wants a capable GPU and plenty of RAM, and the interface has a real learning curve. Some advanced features (certain effects, higher-end noise reduction, some 4K-plus workflows) are reserved for the paid Studio version. Best for long-form projects, color work, and anyone willing to invest a weekend learning it. ## Clipchamp: the Windows default Clipchamp is Microsoft’s browser-based editor, bundled with Windows. At the time of writing, free exports go up to 1080p with no watermark, which already beats a lot of freemium web editors. The timeline is simple and friendly, and there is a decent stock library. The honest catch: premium stock and some filters are flagged and will watermark or block export until you pay, and as a cloud-connected editor your media can be uploaded for some features. It is also strongest inside the Microsoft ecosystem. Best for Windows users who want an easy, familiar timeline for straightforward cuts. ## iMovie: free and clean on Apple devices iMovie ships free on Mac, iPhone, and iPad, and it has never watermarked exports. For basic trimming, titles, transitions, and quick family or school projects on Apple hardware, it remains hard to beat. The honest catch: it is Apple-only, horizontal-first, and intentionally limited. There is no real vertical-video workflow for TikTok or Reels, few advanced tools, and projects do not transfer outside the ecosystem. Best for Mac and iPhone owners making simple horizontal videos. ## Shotcut: open source, everything free Shotcut is a free, open-source desktop editor for Windows, Mac, and Linux. There is no watermark, no paid tier, and no feature wall at all: filters, keyframes, and wide format support are all just there. The honest catch: the interface is utilitarian and occasionally clunky, and you will lean on tutorials for anything past basic cuts. There are no cloud features, which is either a limitation or a privacy feature depending on your point of view. Best for tinkerers who want a truly free desktop editor and do not mind a rougher UI. ## Which one should you pick? Match the tool to the job instead of hunting for one editor that does everything. - Quick social clips, captions, conversions, or sensitive footage: Supercut, right in your browser with nothing uploaded. - Trend-driven TikToks with templates and effects: CapCut, if you are comfortable with its cloud and ownership picture. - Long-form projects and serious color work: DaVinci Resolve, if your hardware can carry it. - Simple timeline edits on Windows: Clipchamp. - Basic horizontal videos on Apple devices: iMovie. - A fully free desktop editor with no walls anywhere: Shotcut. ## FAQ **Why do free video editors add watermarks?** The watermark is marketing: every video you share advertises the tool and nudges you toward the paid plan that removes it. Editors with other business models, like paid pro tiers (DaVinci Resolve), platform bundling (iMovie, Clipchamp), or ecosystem growth (CapCut), do not need to stamp your exports. **Does CapCut add a watermark to exports?** Standard CapCut exports do not carry a watermark at the time of writing. Some templates append a branded outro that you can remove before exporting, and some features now require the Pro subscription. Details change, so check the export preview before you publish. **Is there really no catch with these free editors?** There is always a catch, it is just not a watermark. Expect feature paywalls (CapCut Pro, Resolve Studio, Clipchamp premium stock), platform locks (iMovie), learning curves (Resolve, Shotcut), or cloud processing where your footage travels to a server. Pick the catch you can live with. **How do I remove a watermark from a video I already exported?** The clean answer is to go back to the source file and re-export with a tool from this list, because cropping or blurring over a watermark costs you framing or quality. Removing another creator’s watermark from their content is a different matter and not something we recommend. **Is Supercut completely free?** You can try your first export free with no account, and exports do not carry a Supercut logo. Unlimited watermark-free exports and every tool come with a paid plan, from 4.99 per month billed yearly (59.88 per year), 9.99 monthly, or 199 one-time lifetime. You can cancel anytime. --- # Is CapCut safe? What its privacy policy actually says > A level-headed look at CapCut safety in 2026: who owns it, what data it collects, the lawsuits and US ban saga, and when you should edit locally instead. Source: https://www.supercut.cc/blog/is-capcut-safe Category: Privacy. Published: 2026-07-12 ## Key takeaways - CapCut is a legitimate app from ByteDance, TikTok’s parent company. The safety question is really a data question. - Its privacy policy describes collecting the content you work with plus device and usage data, and cloud features involve uploading footage to servers. - Its US availability has shifted with the TikTok legal saga, and its terms have drawn criticism for broad content-license language. - For sensitive footage, the structural fix is an editor where footage never leaves your device at all. CapCut is one of the most installed video editors in the world, and one of the most googled questions about it is whether it is safe. The short answer: it is not malware, and for everyday creative work most people will be fine. The longer answer is about where your footage and data go when you use it, and that answer is worth understanding before you edit anything sensitive. This is a level-headed walkthrough, not a scare piece. ## Who makes CapCut, and why that is the headline CapCut is developed by ByteDance, the same Chinese company that owns TikTok. That single fact drives most of the safety debate, because the concerns raised about TikTok, including data access, government jurisdiction, and US legislation aimed at ByteDance-owned apps, apply to CapCut too. None of that makes CapCut a virus. It is a polished, widely used app distributed through official app stores. But "is it safe" is the wrong question to ask of any cloud editor. The better questions are: what does it collect, where does my footage go, and who could access it? Those have knowable answers. ## What the privacy policy actually covers Read CapCut’s privacy policy (the current version, since these documents change) and a few categories stand out. It describes collecting the user content you create or upload, which for cloud features means your actual footage. It collects device information, usage data, and general location. Depending on the features you use and the permissions you grant, it can process technical details from your media and interactions. Two practical consequences follow. First, when you use cloud-backed features such as cloud storage, some effects, or cross-device sync, your video travels to ByteDance servers and a copy exists outside your control while it is processed or stored. Second, like most free apps, the product improves and monetizes through the data it observes. That is a normal trade in consumer software, but it is a trade, and you should know you are making it. ## The ban saga and the lawsuits, briefly CapCut’s US availability has been genuinely turbulent. In January 2025 it went offline in the United States for a short period alongside TikTok when federal legislation targeting ByteDance apps took effect, then returned as enforcement was paused and deal frameworks were negotiated. The legal situation has continued to evolve since, so if long-term availability matters to your workflow, check the current status rather than assuming. Separately, CapCut has faced lawsuits, including class actions alleging excessive data collection. Those are allegations rather than findings, and companies settle or contest such suits all the time. In 2025 an update to its terms of service also drew widespread criticism for broad license language over user content, wording that grants the service extensive rights to host, reproduce, and adapt what you upload. Broad licenses like that are common across cloud platforms, but creators posting commercial or client work should read the current terms and decide if they are comfortable. ## So is it actually safe to use? For a hobbyist cutting vacation clips or trend videos, CapCut is fine in the everyday sense: it is not going to infect your device, and the data it collects is broadly similar in kind to what other big free cloud apps collect. If that describes you, the reasonable move is to use it with eyes open. The calculus changes with the stakes of your footage. Client work under NDA, unreleased products, journalism with identifiable sources, legal or medical material, footage of children: for any of these, the issue is not CapCut specifically, it is that cloud processing creates server-side copies you cannot audit, under terms you do not control, in a company subject to its own jurisdiction and business pressures. No privacy settings toggle can fully remove a structural property of the architecture. ## If you keep using CapCut, do this You can meaningfully shrink the data trade without giving up the app. - Skip cloud sync and cloud drafts for anything sensitive, and keep those projects on one device. - Review app permissions: it needs your media library, but reconsider precise location or contacts. - Read the current terms before uploading commercial or client work, and get client sign-off if the license language matters. - Keep your own originals. Never let any editor, CapCut included, hold the only copy of your footage. - Re-check the policy and the app’s legal status occasionally, because both have changed more than once. ## The structural alternative: editing where nothing uploads The cleanest fix for cloud-copy risk is an editor that never makes a cloud copy. Supercut runs the entire edit in your browser: FFmpeg compiled to WebAssembly decodes, edits, and re-encodes your footage on your own device. You type what you want in plain English, and the only thing that leaves your machine is that text prompt plus basic metadata like duration and filename, so the AI can plan the edit. The pixels stay local, which you can verify by loading the page, going offline, and finishing the edit anyway. That architecture will not replace CapCut’s template library for trend content, and it is not trying to. It covers the practical middle of editing, trimming, cropping and reframing, captions, audio cleanup, color, compression, and format conversion, for people whose footage should not be sitting on anyone’s server. Your first export is free with no account, so testing the claim costs nothing. ## FAQ **Is CapCut a virus or malware?** No. CapCut is a legitimate application from ByteDance, distributed through official app stores. The safety discussion is about data collection, content licensing, and cloud processing, not malicious code. **Does CapCut own the videos you make?** Ownership stays with you, but its terms of service grant the company a broad license to host, reproduce, and adapt content you upload, language that drew significant criticism in 2025. A license is not ownership, but for commercial or client work you should read the current terms and judge whether that grant is acceptable. **Was CapCut banned in the US?** It went offline in the US briefly in January 2025 under legislation targeting ByteDance apps, then came back as enforcement was paused and negotiations continued. Its status has kept evolving since, so check current news rather than relying on any snapshot, including this one. **Does CapCut upload my videos to its servers?** When you use cloud features such as cloud storage, sync, or certain effects, yes, your footage is uploaded and processed on ByteDance servers. Purely local edits keep more on your device, but the app is designed around an account and cloud services, and its policy describes collecting user content. **What is the safest way to edit sensitive footage?** Use a tool where the footage never leaves your device. Supercut does the edit in your browser via WebAssembly, sending only your text prompt and basic metadata, never the video itself. You can even go offline after the page loads and still finish the edit and export. --- # Where your video actually goes when you edit it online > Most online video editors upload your footage to their servers. Here is what happens to it there, the questions to ask, and how to verify what a tool sends. Source: https://www.supercut.cc/blog/where-your-video-goes-when-you-edit-online Category: Privacy. Published: 2026-07-13 ## Key takeaways - Most web-based editors work by uploading your footage to their servers, editing a proxy, and rendering in the cloud. - Server copies are governed by retention windows, license terms, and jurisdictions you do not control. - You can verify any editor’s behavior yourself with the browser’s network tab or a simple offline test. - In-browser processing via WebAssembly is the structural alternative: the edit happens on your device and no server copy ever exists. Drop a clip into a typical online video editor and a progress bar appears. That bar is your footage leaving your computer. Most people never think about what happens after that, and most editors would prefer to keep it that way. This post walks through the standard cloud editing pipeline, what can happen to the copies it creates, and how to check, in about a minute, what any editor really does with your files. ## The standard cloud editing pipeline Nearly every mainstream online editor follows the same architecture. Your file uploads to the service’s storage. Servers transcode it into a lower-resolution proxy that streams back to your browser, which is what you actually scrub and cut. Your edits are a list of instructions kept on their side. When you export, their render farm applies those instructions to the original at full quality and hands you a download link. This design exists for good reasons: it works on weak hardware, enables collaboration, and lets the service use powerful GPUs. But notice what it implies. From the moment the upload finishes, the working copy of your video lives on infrastructure you do not control, and everything that happens next is governed by policy documents rather than by physics. ## What can happen to a server copy None of the following requires anyone to act in bad faith. These are structural properties of footage sitting on someone else’s systems. Retention: "deleted" projects often persist in backups and caches for weeks or months, and some services keep uploads indefinitely unless you explicitly purge them. Licensing: terms of service commonly grant the provider a broad license to host, reproduce, and adapt your content, and some reserve rights to use content for improving services, which can include training models. Access: employees, contractors, and subprocessors may be able to reach stored media under support or moderation workflows. Breaches: any stored copy is exposed if the provider is compromised. Legal process: footage on a server can be subpoenaed or produced in discovery without your involvement, which matters enormously for journalists and lawyers. Jurisdiction: your files sit wherever the provider’s data centers and corporate obligations sit, not where you sit. ## Six questions to ask any online editor You can evaluate any service in a few minutes by looking for the answers to these in its privacy policy and terms. - Is my footage uploaded at all, and for which features? - How long is it retained after I delete a project, including backups? - What license over my content do the terms grant, and does it survive deletion? - Is my content used to train or improve models, and can I opt out? - Who can access stored media (employees, subprocessors), and under what controls? - Where is it stored, and which jurisdiction’s law applies? ## How to verify what a tool actually sends You do not have to take any vendor’s word for it, including ours. Two checks settle it. First, the network tab. Open your browser’s developer tools, switch to the Network panel, then add a large video to the editor. If you see requests uploading hundreds of megabytes to the service’s domain, your footage is leaving. If you only see small requests, text and metadata, the processing is local. Second, the offline test, which is even simpler: load the editor, turn off Wi-Fi, and try to complete an edit and export. A cloud editor stops working because its servers are unreachable. A genuinely local editor keeps going, because everything it needs is already on your machine. ## The alternative: editing that never uploads WebAssembly changed what a browser tab can do. FFmpeg, the same engine that powers much of the video industry, now runs inside the page, which means decoding, editing, and re-encoding can happen entirely on your device. That is how Supercut works. There is no upload step, no proxy, and no render farm, because there is no server copy at any point. The one nuance worth being precise about: Supercut is an AI editor, and the AI needs to know what you asked for. So the text of your prompt, plus basic metadata like duration, dimensions, and filename, is sent to plan the edit. The pixels never go anywhere. The plan comes back as a structured instruction, a deterministic engine maps it to exact FFmpeg commands, and your own processor does the work. Both verification tests above pass: the network tab shows no footage leaving, and once the page is loaded you can go offline and still export. ## Who should care the most For a meme edit, cloud copies are a shrug. For some work they are disqualifying. Journalists protecting sources, and anyone handling footage where a subpoena, breach, or moderation queue would be a serious problem: legal teams, healthcare workers, HR departments. Agencies editing unreleased product launches under NDA. Parents who would rather their kids’ videos not live on a server at all. Creators in countries where platform data is accessible to authorities. If you are in any of those groups, the fix is architectural, not contractual. A better privacy policy is still a promise; local processing is a property. Pick tools where the footage physically cannot leave, and the whole category of server-side risk disappears. ## FAQ **Do all online video editors upload my footage?** Almost all of the well-known ones do, because their architecture depends on server-side proxies and cloud rendering. The exceptions are editors built on in-browser processing (WebAssembly), like Supercut, where the edit runs on your own device and no upload happens. **If I delete my project, is my video gone from their servers?** Not necessarily right away. Deletion typically removes your access first, while copies can persist in backups and caches for a retention window defined in the privacy policy. Some services also retain derived data. Check the policy for concrete retention numbers. **How can I tell if an editor is really local?** Two quick tests: watch the browser’s network tab while importing a large file (local tools send text and metadata, not hundreds of megabytes), and try finishing an edit with Wi-Fi off after the page loads. A local editor keeps working offline; a cloud editor cannot. **Does Supercut send anything at all?** Yes, two small things: the text prompt you type and basic metadata (duration, dimensions, filename), so the AI can plan the edit. The footage itself is decoded, edited, and re-encoded in your browser and never leaves your device. **Is local in-browser editing worse than cloud editing?** It trades server power for privacy. Your own device does the work, so very large files depend on your machine’s memory, and there is no multi-user cloud project. For trims, crops, captions, audio cleanup, compression, and conversions, the local approach is fast, and the privacy is absolute rather than contractual. --- # How to turn long videos into Shorts, Reels, and TikToks > A repeatable workflow for cutting long videos into vertical clips: find the moments, trim, reframe to 9:16, caption, and export for each platform. Source: https://www.supercut.cc/blog/turn-long-videos-into-shorts Category: Workflow. Published: 2026-07-14 ## Key takeaways - Clipping is a pipeline, not five separate editing projects: mark moments, trim, reframe, caption, export. - Pick moments with a hook in the first two seconds and exactly one idea per clip. - Reframe to 9:16 with face tracking so moving subjects stay centered, then caption for sound-off viewing. - The same prompt sequence works for every clip, which is what makes the pipeline fast. One good long recording, a podcast episode, a webinar, a stream, a talking-head video, usually contains five or ten short clips that can carry your channel for a week. Most creators never extract them because the process feels like editing five videos from scratch. It is not. Clipping is one repeatable pipeline, and once you have run it twice it takes minutes per clip. Here is the whole workflow, start to finish. ## Step 1: mark the moments while you watch Play your long video once at normal or 1.5x speed with a notes file open. Every time something lands, write the timestamp and a two-word label. You are hunting for four kinds of moments: strong claims (anything that would make a stranger stop scrolling), emotional beats (laughter, surprise, frustration), concrete demonstrations (the before-and-after, the reveal), and clean self-contained explanations of one idea. Be ruthless about the "one idea" rule. A clip that covers two points holds nobody. Aim for moments that will cut to somewhere between 20 and 60 seconds, and collect more candidates than you plan to publish, because some will die in the edit when you discover the setup rambles or the payoff depends on context the clip cannot carry. ## Step 2: cut each moment out With timestamps in hand, the cuts are one prompt each. Drop the long video into Supercut and type the range: "trim from 12:40 to 13:15." The AI plans the cut, a deterministic engine runs it locally in your browser, and nothing uploads, which matters when the source is an unreleased episode or client material. Two trimming habits make clips noticeably better. Start the clip a beat after the thought begins, so the first words are already the hook rather than a wind-up like "so anyway, the thing I wanted to mention." And end it the moment the idea completes. Trailing seconds kill replays, and replays are what the algorithms reward. ## Step 3: reframe to vertical 9:16 Long-form video is almost always 16:9, and every short-form feed is 9:16, so each clip needs reframing, not just posting. A straight crop ("crop to 9:16") works when the subject sits still in the center, like a locked-off talking head. When the subject moves, or the framing is wide, use smart reframe instead: "smart reframe to 9:16 and keep my face centered." Face tracking runs on your device and pans the vertical window to follow the subject, so a speaker who drifts across a wide stage shot stays in frame. Check the result for headroom and re-prompt if the crop sits wrong. If you are unsure which to use, smart reframe is the safer default. ## Step 4: captions, because most viewers are on mute A large share of short-form viewing happens with the sound off, so uncaptioned clips forfeit those viewers in the first second. Type "add captions, big bold style" and Supercut transcribes the audio with an on-device Whisper model, times each word to the speech, and burns the text into the frame. Because transcription is local, the audio never leaves your machine either. Skim the preview before export: proper nouns, brand names, and jargon are what any transcriber gets wrong, and they are exactly the words your audience will notice. Fix the text, then move on. Caption after reframing, not before, so the text is sized and placed for the vertical frame. ## Step 5: export per platform and post natively Export each clip as a 9:16 MP4 at 1080x1920, the size TikTok, Reels, and Shorts all want. Supercut has platform presets, so "export for TikTok" or "export for Shorts" gets the format right without memorizing numbers. Upload natively to each platform rather than cross-posting watermarked exports from one app to another, since platforms tend to suppress each other’s watermarks. The whole render happens in your browser, so there is no upload-render-download round trip per clip. Trim, reframe, caption, export, next clip. After the first one, each additional clip is the same four prompts with different timestamps. ## What separates clips that work from clips that don’t Format gets you to the starting line; these are the judgment calls that decide the race. - Hook inside two seconds: the first line on screen must create a question or a promise. - One idea per clip, stated fully. If it needs context from the long video, it is not a clip. - Cut the wind-up: start mid-energy, not at the beginning of the sentence. - End before it drags: a clip that feels slightly too short gets replayed, one that feels long gets swiped. - Readable captions: big, high-contrast, and out of the way of faces and platform UI. ## FAQ **How long should clips from a long video be?** Twenty to sixty seconds covers most winners: long enough to deliver one idea with a hook and a payoff, short enough to hold attention and earn replays. Under 15 seconds usually cannot carry an idea, and past a minute retention decays fast unless the content is exceptional. **How many shorts can I get from one long video?** A one-hour conversation typically yields five to ten publishable clips. Mark every candidate moment on the first pass and expect to discard a third of them in the edit, when the setup or payoff turns out not to survive isolation. **Do I upload my long video to make the clips?** Not with Supercut. The full-length file loads into your browser and every trim, reframe, caption, and export runs locally through WebAssembly. Only your text prompts are sent so the AI can plan each edit, which matters when the source material is unreleased or client-owned. **Can I use the same clip on TikTok, Reels, and Shorts?** Yes. All three want vertical 9:16 at 1080x1920, so one export usually serves all of them. Export cleanly and upload natively to each platform instead of reposting a file that carries another platform’s watermark, which feeds tend to suppress. **What if the speaker moves around in the wide shot?** Use smart reframe instead of a fixed crop. On-device face tracking pans the 9:16 window to follow the subject, keeping a moving speaker centered without you keyframing anything by hand. --- # Video editing for beginners: you can skip the timeline > The beginner guide to video editing that skips the timeline: the six terms that matter, the six edits that cover most videos, and the easiest way to start. Source: https://www.supercut.cc/blog/video-editing-for-beginners Category: Explainer. Published: 2026-07-15 ## Key takeaways - You need about six terms to be functional: trim, crop, aspect ratio, resolution, format, and export. - Six edits cover the overwhelming majority of real videos: trim, reframe, caption, clean audio, adjust color, compress. - Timelines are a professional’s tool. Prompt-based editing lets you say "trim the first 10 seconds and add captions" and skip the interface entirely. - The fastest way to learn is to finish one small real video, not to watch tutorials. Most beginner video editing guides start by teaching you a timeline: tracks, playheads, keyframes, razor tools. Then most beginners quit, because the interface was built for professionals cutting films, not for someone who wants their clip shorter, vertical, and captioned. Here is the honest beginner path: the handful of words worth knowing, the six edits that cover nearly every video you will make, and why in 2026 you can describe an edit in plain English instead of learning software. ## The only vocabulary you actually need Trim (or cut) means removing time: shaving the start, the end, or a chunk from the middle. Crop means removing space, cutting away parts of the picture, and reframing is cropping with intent, like turning a wide shot into a tall one. Aspect ratio is the shape of the frame: 16:9 is wide (YouTube), 9:16 is tall (TikTok, Reels, Shorts), 1:1 is square. Resolution is the pixel count, where 1080p is the everyday standard. Format (or container) is the file type, and MP4 is the one that plays everywhere. Export means producing the final file after your edits. That is genuinely it. Bitrate, codecs, color spaces, and keyframes exist, and you can learn them the day a project demands it. Nothing on that second list should stand between you and your first finished video. ## Why editing software feels so hard Traditional editors are non-linear editing systems, a design lineage that goes back to cutting film into strips and rearranging it. Tracks, bins, scrubbing, and razor blades are all metaphors from that world. They exist because a feature film has thousands of decisions per minute, and a professional needs total control over every one of them. Your TikTok does not. The mismatch is the problem: you bring a two-decision job, make it shorter and put words on it, to an interface with two hundred controls. Feeling overwhelmed by that is not a talent deficit, it is a tooling mismatch. Recognizing this saves beginners months of guilt-driven tutorial watching. ## The six edits that cover almost everything Watch what non-professionals actually do to videos and the same six operations appear over and over. - Trim: cut the dead air at the start and end. The single highest-value edit that exists. - Reframe: make it 9:16 for phone feeds, or crop distractions out of the frame. - Caption: put timed words on screen, since much of social video plays on mute. - Clean the audio: reduce background hiss and hum, and even out the volume. - Adjust the look: brighten a dark clip or apply a simple color grade. - Compress or convert: make the file small enough to send, in a format (MP4) that opens anywhere. ## The 2026 shortcut: describe the edit instead All six of those edits share a property: you can state them in one English sentence. "Trim the first 10 seconds." "Crop this to 9:16 for Reels." "Add captions, big bold style." "Remove the background noise." For edits like that, the timeline was always ceremony, and prompt-based editors remove it. In Supercut you drop a clip into the browser, type the sentence, and an AI plans the edit while a deterministic engine executes it precisely on your device. Nothing uploads, and there is no interface to study first. Be equally clear about what this does not replace: multi-layer compositing, narrative cutting between many cameras, motion graphics. If you fall in love with editing and head that way, a timeline will be waiting, and DaVinci Resolve’s free tier is an excellent place to learn it. The point is sequencing: finish videos first, adopt professional tools when a project actually demands one, not as an entry fee. ## Beginner mistakes worth skipping Five patterns account for most beginner frustration, and all five are avoidable on day one. Over-editing: effects and transitions on every cut read as amateur, while clean cuts read as confident. Editing the compressed copy: always edit the original file, not the version WhatsApp or a messaging app already crunched. Re-compressing repeatedly: every export loses a little quality, so make your edits in one pass from the source instead of exporting, re-importing, and exporting again. Ignoring audio: viewers forgive soft images but not painful sound, so fix noise and levels before touching color. Wrong shape for the platform: a 16:9 video posted to Reels sits in a letterboxed strip, so reframe before posting, not after the views disappoint. ## Your first project, in fifteen minutes Learning happens by finishing, so finish something today. Take any clip from your phone. Open the Supercut editor in your browser, drop the clip in, and it loads locally with no account needed for your first export. Type "trim the first N seconds" to cut your dead air. Type "crop to 9:16" if it is headed anywhere vertical. Type "add captions" if anyone speaks. Preview, then export. That is a real edited video, made with the same operations you will use on your hundredth one. The difference between people who edit and people who mean to is not software knowledge, it is one finished clip, then another. ## FAQ **What is the easiest way to start editing videos?** Start with a prompt-based editor and one real clip. Typing "trim the first 10 seconds and add captions" produces a finished video in minutes with no interface to learn, and the concepts you pick up (trim, crop, aspect ratio, export) transfer to any editor you use later. **Do I need to learn a timeline editor eventually?** Only if your projects demand one: multi-camera narrative work, layered compositing, motion graphics. For trims, reframes, captions, audio cleanup, and format conversion, which is most of what most people ever do, you never need a timeline at all. **What software should a complete beginner use?** For sentence-shaped edits, Supercut in your browser, where you describe the edit in plain English, nothing installs, and nothing uploads. If you later want a full professional timeline, DaVinci Resolve’s free version is the strongest no-cost option to grow into. **What resolution and format should beginners export?** MP4 at 1080p is the default that works essentially everywhere. Go 9:16 (1080x1920) for TikTok, Reels, and Shorts, and 16:9 (1920x1080) for YouTube. You can state that in the prompt or use a platform preset. **Is video editing hard to learn?** The six edits that cover most real videos are not hard, and with prompt-based tools they are one sentence each. What is hard is professional editing software, which most beginners never actually need. Do not confuse the two. --- # What is AI video editing? What it can and can’t do in 2026 > AI video editing means three different things: generated video, AI-assisted tools, and prompt-driven editing. What each does well, where they fail, and how to choose. Source: https://www.supercut.cc/blog/what-is-ai-video-editing Category: Explainer. Published: 2026-07-16 ## Key takeaways - Generative video creates footage from text; AI-assisted editors automate tasks inside a timeline; prompt-driven editors execute plain-English edits on your real footage. - AI is genuinely reliable at transcription, face tracking, scene detection, audio cleanup, and translating intent into edit plans. - AI has no taste: it cannot decide what makes your video good, and unchecked AI output still needs review. - The architecture question that matters: does the AI see your pixels in the cloud, or only your instructions? "AI video editing" has become a label stuck on three genuinely different technologies: models that generate footage from text, traditional editors with AI features bolted on, and editors where you describe changes to real footage in plain English. They solve different problems, fail in different ways, and get conflated in almost every product page you will read. Here is the sober map: what each one actually is, what AI reliably does well in an edit today, and the questions that cut through the marketing. ## Three technologies wearing one label Generative video models (the Sora and Veo family, and their successors) synthesize new footage from a text description. Nothing existed before the prompt; the model dreams the pixels. This is creation, not editing, and it is the technology behind both the impressive demo reels and the "AI slop" flooding feeds. AI-assisted editing is a traditional timeline editor with machine-learning features embedded: auto-transcription, text-based cutting, background removal, reframing suggestions, filler-word removal. You still operate the editor; AI accelerates specific tasks inside it. Prompt-driven editing inverts the interface. You state the outcome in plain English ("trim the first 10 seconds, crop to 9:16, add captions") and the system plans and executes real operations on your real footage. Supercut is built this way: an AI turns your sentence into a structured edit plan, and a deterministic engine maps that plan to exact FFmpeg commands that run in your browser. The AI never touches pixels; it plans, and conventional video processing executes. ## What AI reliably does well in an edit today Strip away the hype and a solid core of capabilities has become dependable. - Transcription: on-device models like Whisper turn speech into accurately timed captions in many languages. - Face detection and tracking: finding faces and following them through frames, which powers smart reframing to 9:16 and automatic privacy blurs. - Scene detection: locating the cut points in footage, useful for splitting long recordings. - Audio cleanup: separating steady background noise from speech and evening out loudness. - Intent translation: turning "make it vertical for TikTok and caption it" into the correct sequence of concrete operations. The same pattern shows up on either side of the edit itself. While AI video editing tools enhance tasks like transcription and scene detection, Bustinger complements this by [automating YouTube spam removal](https://bustinger.com/), ensuring creators can maintain genuine audience engagement without manual moderation. ## What it can’t do, and where the failure modes hide AI has no taste. It cannot know that the third take is the one where your delivery landed, that a pause should breathe instead of being trimmed, or that your brand would never use that transition. Editing judgment, what makes a video good rather than merely finished, remains entirely yours, and any product implying otherwise is overselling. The failure modes differ by category, and knowing them is most of the defense. Generative video hallucinates: physics, hands, text, and continuity can silently go wrong, and using it means reviewing every frame. AI-assisted features misfire locally: a transcript mangles your product name, auto-reframe follows the wrong face. Recoverable, if you check. Prompt-driven editing’s risk is misinterpretation: the plan does not match what you meant. The honest mitigations are architectural: deterministic execution (the same plan always produces the same result, so nothing drifts mid-render), showing you the plan before it runs, and previews before export. That determinism is why Supercut separates the AI that plans from the engine that executes. ## The privacy question nobody puts on the pricing page AI features need compute, and where that compute runs decides where your footage goes. Most cloud AI editing sends your video to servers for processing, which means copies of your raw footage exist outside your control, governed by retention policies and terms you should actually read, including whether uploads can be used to improve or train models. It does not have to work that way. Modern browsers run real models locally: Whisper transcribes on your device, face tracking runs on your device, and WebAssembly executes FFmpeg on your device. Supercut’s split is explicit: the language model that plans your edit sees the text prompt and basic metadata (duration, dimensions, filename), never the pixels, and every pixel operation happens in your browser. When evaluating any AI editor, ask the one-sentence version: does the AI see my footage, or only my instructions? ## How to evaluate an AI video editor Five questions separate genuine utility from a demo reel. Does it save minutes on jobs you actually do every week, or only on contrived showcase tasks? Can you see and correct what the AI decided, or is it a black box between you and the export? Where does processing run, and what leaves your device? Is execution deterministic, or can the same request produce different results on different days? And what does failure cost: a wasted preview, or a published mistake? Tools built for real workflows answer these plainly. Marketing built on vibes changes the subject. ## FAQ **What does AI video editing actually mean?** One of three things: generating new footage from text (Sora-style models), AI features inside a traditional timeline editor (auto-captions, reframing), or prompt-driven editing where you describe changes to real footage in plain English and the system executes them. They are different technologies with different strengths. **Can AI edit my video automatically?** It can execute well-defined operations automatically: transcribe and caption, track a face and reframe, cut at scene boundaries, clean audio. It cannot decide what makes your video good. Treat AI as a very fast operator and keep the judgment calls yourself. **Does AI video editing mean my footage is analyzed in the cloud?** Often, but not necessarily. Many tools upload footage to cloud GPUs, while others run models on your device. Supercut sends only your text prompt and file metadata to the AI that plans the edit; transcription, face tracking, and all pixel processing run locally in your browser. **Will AI replace video editors?** It is replacing the mechanical layer: transcription, rote cutting, format conversion, first-pass cleanup. The scarce skill was never dragging clips on a timeline, it was knowing what to keep and why. People with taste get faster; taste itself is not automated. **What is the difference between generative video and AI editing?** Generative video creates footage that never existed, from text. AI editing operates on footage you shot: trimming, reframing, captioning, cleaning. If your starting point is real video you need improved rather than imagined, you want an editor, not a generator. --- # Online vs desktop video editors: which should you actually use? > Browser editors win on instant access, desktop wins on heavy projects. The real differences, the upload catch most online editors hide, and when you need both. Source: https://www.supercut.cc/blog/online-vs-desktop-video-editors Category: Explainer. Published: 2026-07-17 ## Key takeaways - Online editors win on instant access from any machine; desktop editors win on heavy projects, huge files, and guaranteed offline work. - The hidden catch of most online editors is the upload: your footage travels to their servers, with speed, size, and privacy consequences. - In-browser processing (WebAssembly) breaks the old trade-off: online convenience with local, private processing. - Supercut ships the same private editor both ways: a browser app and a desktop app for Mac and Windows. The online-versus-desktop question sounds like a simple convenience trade: click a link now, or install something powerful. The real differences run deeper, and the most important one, what happens to your footage, barely gets mentioned in most comparisons. Here is where each side genuinely wins, the catch hiding inside most online editors, and why the answer for a lot of people in 2026 is quietly "both." ## What actually differs (it is not just the install) Setup: a browser editor is a URL, ready in seconds on any machine, including a locked-down work laptop. Desktop software is a download, an install, sometimes a license activation, repeated per machine. Power: desktop editors own the high end. Long timelines, layered effects, color grading suites, and plugin ecosystems live in DaVinci Resolve and Premiere, and they use your GPU directly. Files and offline: traditional online editors impose upload limits and need a connection for everything; desktop apps eat any file your hardware can hold and never care about Wi-Fi. Updates and price: web apps update silently and usually bill as subscriptions; desktop software ranges from genuinely free (Resolve’s free tier) to perpetual licenses to subscriptions of their own. ## The catch inside most online editors The comparison above hides an architectural fact: nearly every mainstream online editor is a cloud editor. Importing a clip means uploading it to their servers, where it is transcoded, edited by proxy, rendered, and stored. Three consequences follow. Speed: a multi-gigabyte file spends real time crawling up your connection before you can make the first cut. Limits: free tiers cap upload size, resolution, or export minutes, because server compute costs the vendor money. Privacy: a copy of your footage now lives under someone else’s retention policy, terms of service, and jurisdiction. For casual clips those are shrugs. For client work, unreleased material, or anything sensitive, the third one is disqualifying, and it is the reason "online editor" earned a reputation for being convenient but compromised. ## The third option that breaks the trade-off WebAssembly quietly ended the assumption that online means uploaded. FFmpeg, the industry-standard processing engine, now runs inside the browser tab itself, so a web app can decode, edit, and re-encode video on your own device, exactly like desktop software, while still being a link you open. Supercut is built on this. You drop a clip into the page and it loads locally; you type the edit you want in plain English; an AI plans it and a deterministic engine executes real FFmpeg commands in the tab. There is no upload step at all, which you can verify by watching the network tab or by going offline after the page loads and finishing the edit anyway. You get the online column’s convenience (nothing to install, works on any machine) with the desktop column’s privacy and file handling. The remaining limit is honest: the work runs on your hardware, so enormous 4K files depend on your machine’s memory rather than on a render farm. ## When you still want true desktop software In-browser processing covers the practical middle of editing, but the high end still belongs to installed suites. Choose a desktop NLE when your project is long-form with complex narrative structure, when you are compositing many layers with effects and motion graphics, when you need a plugin ecosystem or professional color and audio finishing, or when you routinely cut multi-hour 4K footage that wants every gigabyte of RAM and GPU you own. Supercut also ships as a desktop app for Mac and Windows, the same prompt-based private editor in a native window, for people who want it in the dock, working offline by default, independent of the browser. You can grab it from the download page. It is deliberately not trying to be Resolve; it is the fast private tool for the edits you do every week, in whichever form factor you prefer. ## The decision in four questions Skip the feature matrices and ask these. - Is the edit sentence-shaped (trim, reframe, caption, compress, convert)? Browser-based Supercut, done in minutes, nothing uploaded. - Is the footage sensitive or client-owned? Then the tool must process locally, whether in-browser or installed. Cloud editors are out. - Is it a long-form, multi-layer, effects-heavy project? Install a desktop NLE; DaVinci Resolve free is the strongest starting point. - Do you edit on many machines or a locked-down one? A browser editor is the only option that follows you everywhere. ## FAQ **Are online video editors worse than desktop ones?** Not worse, scoped differently. Online editors optimize for access and simple-to-moderate edits; desktop suites optimize for power. The historical online weaknesses (upload waits, size caps, footage on servers) come from cloud architecture, and in-browser editors like Supercut avoid them by processing locally. **Do online video editors upload my footage?** Most do, because they edit and render on their servers. In-browser editors are the exception: Supercut processes everything locally via WebAssembly, and only your text prompt plus basic metadata is sent, never the video. **Can browser-based editors handle big files?** Reasonably big, yes, since there is no upload cap at all: the file never travels. The practical limit is your device’s memory, because your own hardware does the processing. Multi-hour 4K masters are still desktop-NLE territory. **Is there a desktop version of Supercut?** Yes, for Mac and Windows, available on the download page. It is the same prompt-based editor with the same privacy model: footage processed on your machine, nothing uploaded, working offline. **What should a beginner pick, online or desktop?** Start online with a prompt-based editor and finish real videos this week; there is nothing to install and nothing to learn first. Add desktop software later only if a project genuinely demands timelines, layers, and effects. --- # How to send large video files without wrecking the quality > Four ways to send a video that is too big: compress it, trim it, share a link, or transfer locally. Platform size limits and the best option for each case. Source: https://www.supercut.cc/blog/how-to-send-large-video-files Category: Workflow. Published: 2026-07-18 ## Key takeaways - Compression is the answer most of the time: downscaling to 1080p with sensible encoding shrinks most phone videos dramatically with little visible loss. - Email caps attachments around 25 MB; chat apps are more generous but re-compress aggressively. - Cloud links preserve full quality but upload your footage to a server, which is a privacy decision, not just a convenience one. - Compress locally in your browser so the file shrinks before it ever travels anywhere. "Video is too large to send" is one of the most universal tech annoyances there is. A minute of modern phone video can run to hundreds of megabytes, while email still lives in a world of 25 MB attachments. There are exactly four ways out: make the file smaller, send less of it, send a link instead, or move it locally. Here is when each one is right, what every option costs you, and the platform limits you are actually fighting. ## Why your video is so big in the first place File size is roughly resolution times bitrate times duration. Modern phones default to high resolutions and generous bitrates, so a minute of 4K footage commonly runs into hundreds of megabytes. Nobody watching on a phone screen or in a chat window can use most of those pixels, which is exactly why compression works so well: you are discarding data the viewer was never going to see. Know what you are up against, with the caveat that platform limits change over time. At the time of writing: mainstream email services cap attachments around 20 to 25 MB. WhatsApp allows media up to roughly 2 GB but re-compresses videos hard unless you send them as documents. Discord’s free upload limit is around 10 MB, one of the tightest anywhere. Slack, Teams, and similar tools sit in between with workspace-dependent caps. The pattern: email is the bottleneck, chat apps are roomier but mangle quality, and everything has a ceiling somewhere. ## Option 1: compress it (the answer most of the time) For most sends, the recipient needs to watch the video, not archive a master copy, and compression serves that perfectly. Two moves do almost all the work: downscale the resolution to match reality (4K to 1080p, or 1080p to 720p for chat), and let constant-quality encoding spend bits where the picture needs them. An MP4 with H.264 video is the output that opens on every device your recipient could own. In Supercut this is one prompt: drop the clip into the browser and type "compress this for email" or "compress and downscale to 720p." The AI plans it, the encoding runs locally through WebAssembly, and you preview the result before sending. Note what did not happen: the file never uploaded anywhere to get compressed. Online compressor sites make you send your full-size private video to their server first, which is both the slowest and the least private step in the whole process. Compress locally, then send the small file wherever it is going. ## Option 2: send less video Half the time the honest fix is that nobody needs all seven minutes. If the point of the send is one moment, the goal, the quote, the bug you are reporting, the kid doing the thing, trim to it. A 20-second clip at full quality is usually smaller than a 7-minute clip at any watchable quality, and it is a better message too, because the recipient sees exactly what you meant without scrubbing. Combine the two options and you get the best result available: "trim from 2:10 to 2:45 and compress for email" in one prompt. For anything you send to a group chat repeatedly, this habit alone makes the size problem mostly disappear. ## Option 3: share a link when quality is the point When the recipient genuinely needs the full-resolution file, an editor pulling your footage, a client receiving a deliverable, family archiving the wedding video, compression is the wrong tool. Upload the file to storage (Google Drive, Dropbox, iCloud, WeTransfer and its kin) and send a link. Size stops mattering and quality is untouched. Two eyes-open caveats. First, this is an upload: your footage now sits on a server under that provider’s terms, retention, and security, so for sensitive material choose the provider deliberately and set link permissions tight (specific people, expiry dates where offered). Second, links rot: free transfer services expire, and permissions get confused. For a one-time handoff of a big master file, though, a link is the right call. ## Option 4: move it locally, no internet required Same room, same house, or same office? Skip the internet entirely. AirDrop moves multi-gigabyte videos between Apple devices in seconds at full quality. Nearby Share does the equivalent for Android and Windows. A USB drive or cable remains the unglamorous champion for huge batches. Local network transfer is also the most private option on this list, since the file never touches any server at all. This is the underused option. People burn twenty minutes fighting an upload for a file the recipient is sitting three meters away from. ## Which option for which send Map the send to the method and this stops being a recurring problem. - Emailing a client or colleague: trim to what matters, compress to fit under 25 MB, attach. - Family group chat: compress to 720p or 1080p first; the chat app will re-compress whatever you send anyway. - Discord: trim hard and compress hard, the free cap is tight; or post a link for anything substantial. - Delivering a full-quality master: cloud link with tight permissions, or a local transfer if you are nearby. - Sensitive footage: compress locally in your browser, then hand it over by AirDrop, cable, or another route that never touches a server. ## FAQ **How do I email a video that is too big?** Trim it to the part that matters, then compress it: downscale to 1080p or 720p and export an H.264 MP4. In Supercut that is one prompt ("trim from 0:30 to 1:00 and compress for email"), runs locally in your browser, and usually lands a short clip comfortably under the ~25 MB attachment cap. **Why does WhatsApp destroy my video quality?** WhatsApp re-compresses videos aggressively to save bandwidth. You get better results by compressing the clip yourself first, so its encoder has less to crush, or by sending the video as a document, which skips the aggressive re-encode at the cost of convenience. **How can I send a large video without uploading it to any server?** Compress or trim it locally (Supercut does this in your browser, with the footage never leaving your device), then transfer it locally too: AirDrop, Nearby Share, a cable, or a USB drive. End to end, no server ever holds a copy. **Does compressing a video ruin its quality?** Done once, from the original, with sensible settings, most viewers cannot tell on a phone or laptop screen. Quality death comes from repeated re-compression, so keep your original, compress one copy for sending, and never re-compress an already-compressed file. **What is the best format for sending videos?** MP4 with H.264 video and AAC audio. It opens on effectively every phone, computer, and chat app, and it compresses efficiently. If your clip is a MOV or WebM, convert it to MP4 before sending to spare your recipient playback trouble. --- # Screen recording without uploading your screen > A screen recording captures more than the app you meant to show. What cloud recorders do with it, the questions to ask, and how to record with nothing uploaded. Source: https://www.supercut.cc/blog/screen-recording-without-uploading Category: Privacy. Published: 2026-08-04 ## Key takeaways - A screen recording keeps whatever the screen showed, which routinely includes customer data, internal tools, and notifications nobody planned for. - The standard recorder uploads while you record, stores the file and its transcript, and gives you a share link. The convenience and the exposure are the same feature. - The questions that decide the risk are retention, who can open the link, and what else the stored copy feeds. - Recording locally removes the category rather than managing it: no upload, no hosted copy, no link outliving your memory of making it. Of everything you produce in a working week, a screen recording shows the most. It is not only the app you meant to demo. It is the tab strip, the notification that arrived at 0:42, the customer name in the CRM, the internal dashboard behind the window you were resizing. Most recorders answer that by uploading the file while you record, hosting it, and handing you a link. That is a genuinely useful architecture, and it is worth understanding before you point it at your own screen. ## What is actually inside a screen recording Point a camera at a person and you capture a person. Capture a screen and you capture your whole working context, because a screen is a dense surface of other people’s information. The subject of the recording is the small part; the frame around it is everything else you had open. The accidents are the interesting part. An autocomplete dropdown of real email addresses. A browser bookmarks bar naming three unannounced projects. A chat toast that quotes a colleague verbatim. A staging environment sitting on production data because that is how the seed script works. A pre-launch product, which is a leak with a play button on it. None of these are the thing you set out to record, and all of them go up with it. ## What the standard cloud recorder does with it The dominant design uploads as you record. Chunks stream to the service while you talk, the file is transcoded, a transcript is generated, and the result lives at a URL you can paste anywhere. That is why hosted recorders feel so good: no file to move, no export wait, and a link that works before you have finished thinking about who should have it. The properties that come with it are structural, not sinister. A copy of the recording exists on infrastructure you do not run. The share link is a credential, and unlisted URLs get forwarded, pasted into tickets, and indexed when someone drops one on a public page. Deleting the recording removes your access first, while backups and derived data (transcripts, thumbnails, search indexes) follow their own retention windows. Workspace administrators and support staff can generally reach stored media under some documented process. And the terms of service decide whether uploads can be used to improve the service, which is worth reading rather than assuming. ## Six questions worth asking any screen recorder You can settle most of this in ten minutes with the privacy policy, the terms, and the sharing settings. - Does it upload while I record, or only when I choose to share? - Who can open the link by default: anyone with the URL, everyone in my workspace, or named people only? - When I delete a recording, what happens to the file, the transcript, and the backups, and on what timeline? - Are recordings or transcripts used to improve or train anything, and can I turn that off? - Who inside the company can access stored recordings, and under what process? - Which jurisdiction stores it, and whose legal process reaches it? ## What changes when the recording stays local Recording on your own machine does not reduce the exposure, it removes the category. There is no upload while you record, so a recording you abandon halfway through never existed anywhere but your disk. There is no hosted copy to retain, no link to forward, and no admin console that lists your recording alongside everyone else’s. Deleting the file is deletion, not a request. Be equally clear about what you give up, because it is real. There is no instant share link and no viewer analytics, so you hand the file over yourself, by whatever channel you already trust. Storage and memory are yours: a long recording of a large display is a big file, and your machine does the encoding. For a demo of unreleased work or a walkthrough of a screen full of customer records, that is a trade most people would take without thinking. For a note to a teammate about a button, maybe not. ## How Supercut records with nothing uploaded Supercut records in the browser (Chrome, Edge, Brave, and Arc, with nothing to install) or in the desktop app for Mac and Windows, which adds system audio and cursor tracking. The screen, your microphone, and your camera are captured as three separate tracks, and the camera is never composited into the picture, so the bubble stays movable, resizable, and removable after the take. The recording lands on a timeline already framed on a backdrop, and trimming, zooms, captions, and export all run on your device. One nuance stated precisely, because vague privacy claims are worth nothing. Supercut also has a prompt-based editor, and when you type a prompt, that text plus basic metadata (duration, dimensions, filename) is sent so the AI can plan the edit. The pixels and the audio never go anywhere. If you only record and edit on the timeline, nothing leaves your machine at all. You can check both claims the same way we would: watch the network tab while you record, or load the page, go offline, and finish the whole recording and export anyway. ## When a hosted link is still the right call This is not an argument that hosted recorders are a mistake. Async updates to a distributed team, a walkthrough a hundred people should watch with comments attached, a support reply that has to open in one click on a phone: those are collaboration products, and the upload is what makes them work. Choosing them deliberately is the point. The useful habit is deciding per recording instead of by default. Record locally when the screen carries customer or patient data, when the product has not shipped, when the conversation is an HR or legal matter, or when the bug report means filming a production dashboard. Use the hosted tool for the ordinary rest. What you want to avoid is the situation where the most sensitive recording you ever make goes up the same pipe as a note about a misaligned button, because that was the only recorder installed. ## FAQ **Are screen recorders safe to use?** For ordinary work, mainstream recorders are legitimate software and the answer is yes. The real question is what your screen is showing. A recording of customer records, an internal dashboard, or an unreleased product is a sensitive document, and with a hosted recorder it is stored, transcribed, and reachable by a link. **Does Supercut upload my screen recording?** No. Recording, editing, and export happen on your device, in the browser or the desktop app. There is no server copy and no share link. If you use the prompt-based editor, the text of your prompt and basic file metadata are sent so the AI can plan the edit; the video and audio never are. **How can I check whether a recorder is uploading my screen?** Two tests. Watch your browser’s network tab while you record and look for a steady stream of large uploads to the vendor’s domain. Then load the tool, disconnect from the network, and try to record and export anyway. A local recorder keeps working; an uploading one cannot. **Can I record my screen without creating an account?** Yes. The browser recorder runs in Chrome, Edge, Brave, and Arc with nothing to install, and you can try your first export with no account. Unlimited watermark-free exports and every tool come with a paid plan, from 4.99 per month billed yearly (59.88 per year), 9.99 monthly, or 199 one-time lifetime. **What about my microphone and camera, are those uploaded?** No. They are recorded as their own tracks alongside the screen and stay on your device with everything else. Because the camera is never baked into the picture, you can also shrink, hide, or delete the bubble after the take rather than deciding before it. --- # How to make a screen recording look produced > Raw screen recordings look raw for fixable reasons. Five moves that change it: framing, motion with a reason, pacing, clean sound, and words on screen. Source: https://www.supercut.cc/blog/make-screen-recordings-look-produced Category: Workflow. Published: 2026-08-05 ## Key takeaways - A raw capture reads as raw mostly because it fills the frame edge to edge and never moves with intent. - Framing is the highest return per second of effort: a backdrop, padding, rounded corners, and a shadow. - Zooms should be few, held long enough to read, and aimed at things that are genuinely too small to see. - Pacing and sound beat any effect: cut the loading spinners, clean the microphone, and caption for mute viewing. You can usually tell in the first two seconds whether a screen recording was made by someone who thought about it, and it is almost never the effects that give it away. It comes down to five things, all of them decisions rather than skills: how the recording sits in the frame, whether the motion has a reason, whether the pacing respects the viewer, whether the sound is listenable, and whether the words that matter are on screen. Here they are, in the order worth doing them. ## What actually reads as produced Watch a polished product video next to a raw capture of the same flow. The polished one is rarely doing anything exotic. The recording is inset rather than bleeding to the edges. The camera moves a handful of times, always toward something specific. There is no moment where you watch a spinner or hear someone find their next word. The voice is close and even. And when a detail matters, a word appears on screen. None of that is talent, and none of it needs a motion graphics suite. It is five moves, and four of them are decisions you make once and reuse on every recording after. That is worth saying because the instinct after seeing a good demo is to go looking for effects, when the actual gap is framing, restraint, and deletion. ## Move one: get the recording off the edges of the frame A full-bleed desktop capture reads as a screenshot that happens to move. Inset it instead: put it on a backdrop with a margin around it, round the corners, and give it a soft shadow so it sits on the surface rather than being the surface. This one change does more than everything else on this list combined, and in Supercut it is already applied when a recording lands on the timeline. Two details are worth knowing. Backdrops here are drawn in the page with CSS and SVG rather than loaded as image files, so what you see in the preview is exactly what comes out of the export, on the web and on the desktop app. And each scene keeps to a single hue family, with its light large, soft, and pushed off center, because a tight bright gradient behind an inset window reads as a neon border rather than as depth. Picking a scene also brings its own shadow, since the heavy shadow that seats a window on a dark backdrop turns into a dirty ring on a pale one. ## Move two: motion, but only with a reason The second tell of a raw capture is that the frame never moves while the content it is showing keeps shrinking into illegibility. A screen recording is a large picture displayed small, so the fix is a push-in at the moments where a viewer needs to see a specific small thing: a field, a menu item, an inline error, a number changing. On the desktop app these are largely generated for you. It samples the cursor while you record and turns the places where the pointer settles, and on macOS where you click, into zooms with a lead in and a lead out, so the push-in starts a beat before the action rather than after it. Every one is editable, which matters, because the judgment is yours: hold each zoom long enough to actually read, and delete the ones that fire on something already legible. Four deliberate zooms in two minutes reads as considered. Twelve reads as restless. In the browser there is no cursor tracking outside the page, so you place zooms yourself, which is slower and produces the same result. ## Move three: pacing, which is mostly deletion Every screen recording contains dead time, and viewers feel all of it. The big three are loading spinners, the pause while you find the next sentence, and the stretch where you are navigating to the place where the interesting thing happens. Cut all three. A ninety second version of a three minute demo is not a compromise, it is the same demo with the waiting removed. Much of this is avoidable during the take. Pause the recording while you reset the app for the next beat and resume when you are ready, since paused time is folded out of the final length and costs you nothing. Then in the edit, trim the front to the first useful word, because the strongest opening you have is almost never the sentence you planned as your opening. ## Move four and five: sound, then words on screen Audio decides whether people stay. Get the microphone close, reduce the steady background layer (fans, hum, room tone), and even the levels out so your voice does not drift. If the product itself makes sound and that sound is part of the point, record the system audio too, which the desktop app does on macOS and Windows. Music is optional and, if you use it, should sit far enough under the voice that you stop noticing it. Then put the important words on screen. A large share of demo watching happens on mute in an inbox or a chat thread, so captions are not an accessibility afterthought, they are how half your audience receives the content. Supercut transcribes on your device and times each word to your speech, so the audio does not travel anywhere to become text. A short title card at the top, naming what the viewer is about to see, is the other high-value piece of text: it costs three seconds and prevents the common failure where someone watches a whole demo without ever learning what it was demonstrating. ## The pass that takes five minutes Once the recording is on the timeline, this is the whole checklist. - Inset the recording on a backdrop with padding, rounded corners, and a shadow, then leave that look alone across your recordings so they feel like a set. - Trim to the first useful word, and cut every spinner and hesitation you can find. - Keep the zooms that point at something small, delete the rest, and hold the survivors long enough to read. - Decide the camera bubble: keep it small and out of the way, hide it during zooms, or remove it entirely. - Clean the audio and even the levels, then caption it for the people watching on mute. - Export an mp4 for a page or an email, or a GIF of the best few seconds for a doc or an issue thread. ## FAQ **How do I make a screen recording look professional?** Inset it on a backdrop with padding, rounded corners, and a shadow, add a few well-held zooms where detail matters, cut the loading and hesitation, clean the audio, and caption it. Those five moves carry almost all of the difference, and none of them need motion graphics. **What background should I put behind a screen recording?** A quiet one in a single hue family, with a large soft light rather than a tight bright gradient. The backdrop is only ever seen as a frame around the recording, so anything busy competes with the content it surrounds. Keeping one scene across your recordings also makes them feel like a set. **How many zooms should a screen recording have?** Fewer than instinct suggests. Roughly one every twenty to thirty seconds, and only where something is genuinely too small to read. Each should hold long enough to be read, since a push-in that arrives and leaves inside a second reads as a glitch rather than emphasis. **Should I include a camera bubble?** It depends on the job: a face helps a founder or sales demo and adds nothing to a support walkthrough. In Supercut the camera is recorded as its own track and never composited in, so you can size it, hide it during zooms, or delete it after the take instead of committing before it. **Do I have to upload my recording to add a backdrop and zooms?** No. Recording, framing, zooms, captions, and export all run on your device, in the browser or the desktop app. Nothing is uploaded and exports carry no watermark, which is what makes the polish workable on demos of unreleased work.
