How it works

  1. 1

    Drop your clip

    Load your video in the editor locally.

  2. 2

    Ask to mute

    Preview and download the muted file. Video quality stays intact.

Tips

  • Mute B-roll before dropping in music later.
  • Muting does not touch video quality.
  • Export muted, then add a new track with replace audio.

Why it stays private

Supercut decodes, edits and exports your video entirely in your browser with WebAssembly. Your video files never leave your device. To plan the edit, the AI gets your request, the words said in your clip and its sound levels (both worked out on your device), and a few low-resolution frames only if you turn that on.
