Tips

  • Reels are 9:16, 1080x1920.
  • 15 to 30 seconds tends to perform well.
  • Add music inside Instagram after exporting the video.

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.
