How it works

Three steps, a couple of minutes

Drop in your video

Talking-head clips, podcasts, lessons and screen recordings work best.

Silences are found and cut

The audio is analysed in your browser and the quiet parts are removed.

Review and export

Every cut is a normal edit on the timeline, so you can undo or adjust any of them.

Why it works

Why use CutLuma for this

Private by design

The analysis happens on your device. Your video is not uploaded to find the silences.

Natural-sounding cuts

A short breath is kept around each sentence so the result does not sound chopped.

Faster, tighter videos

Shorter videos with no dead air hold attention longer.

FAQ

Questions? Answers.

How does it decide what is silence?

It measures loudness across the clip and removes stretches of about 0.7 seconds or more that are near the background noise level.

Can I undo a cut?

Yes. Press Ctrl+Z, or drag the edge of any clip to bring a pause back.

Does it work for long videos?

Yes, for files your browser can open — typically up to an hour or two of footage.
