About video scene cuts

This tool runs ffmpeg.wasm with a scene-select filter (gt(scene,THRESHOLD)) to list shot-change timestamps, then lets you pick scenes and download keyframes and/or clips.

The WASM payload is tens of megabytes and analysis scales with duration — use short clips when possible.

    Lower values catch more cuts; higher values fewer.

  3. 3

    Export selection

    Download keyframes and/or clips for checked scenes.
