motion + silence detection

Cut the boring parts out of
long video, automatically.

Kutmo finds the motion and sound, then hands your editor a ready-to-open timeline — dead air gone before you open Premiere.

Drop a video, or a project XML.

Kutmo finds the action and builds a timeline your editor can open.

Your video never leaves the tab. No upload, no account — decode and detection run entirely on your machine.

everything runs in your browser · there is no server that could see your footage

From raw footage to a cut timeline in three steps

No scrubbing, no manual logging. About two minutes, start to finish.

  1. Drop your video

    Drag in a video or an editor XML. It decodes in the tab — nothing uploads.

  2. Tune the detection

    Four sliders tune motion and silence sensitivity. The timeline updates live.

  3. Export to your editor

    One click exports a project for Premiere, Final Cut, or Resolve — cuts already in place.

Built for long, static-camera recordings

Anywhere the boring parts outnumber the good ones.

Painting, building, crafting — keep the strokes, drop the pauses.

Questions

Does my video upload anywhere?
No. Decode and detection run in your tab — there is no backend that could receive your footage.
What does the Free tier include?
Detection and preview are free at any length, no account needed. Exporting needs a free account and includes 5 exports (any format); Pro removes the limit.
How does it get into my editor?
Export a project file and open it in Premiere, Final Cut, or Resolve — cuts already in place. Keep the source video where it is so the editor can link it.
What kind of footage works best?
Long static-camera recordings — time-lapses, lectures, gameplay, podcasts. H.264 .mp4 is the most reliable.
