Tips

  • 0.5 to 1s fades suit most social clips.
  • Fade out on the last beat for a clean ending.
  • Use a fade in to ease into a hard opening shot.

Why it stays private

Supercut decodes, edits and exports your video entirely in your browser with WebAssembly. Your footage is never uploaded, the only thing that leaves your device is the text of your prompt, so the AI knows what edit to plan. Read more in our Privacy Policy.

Frequently asked questions

How long should fades be?

0.5-1s works for most social clips. Longer fades (2-3s) feel more cinematic.

Can I fade in without fading out?

Yes. Specify “fade in only” or “2s fade out” independently.

Is my video uploaded?

No. Fade effects run entirely in your browser.
