How to cut dead air and filler words from videos

A natural pause between sentences is part of speech. Pauses long enough to feel like dead air are the ones to trim. Around half a second is a sensible starting point; lengthen it if the result sounds rushed.

Cutting a pause to zero makes speech sound like a machine gun. Keep a short gap, a tenth of a second or so, so sentences still breathe.

Isolated “um” and “uh” can go. Words like “like” or “so” are often part of how someone talks and part of the meaning, so remove those only by hand, case by case.

A cut in a talking-head shot causes a small jump. Hide it by cutting when the speaker’s position is similar, or add a brief zoom so the jump reads as a deliberate style.

Removing a very large share of a clip changes how the person sounds and can cut out thinking time that makes a point land. If most of a clip is being cut, the clip itself is probably the problem.

Play the tightened version at normal speed with headphones. If any cut sounds like a stumble, put that pause back. Then watch it once more with the sound off, to make sure the picture doesn’t jump in a way that distracts from the words.

The ways tightening backfires:

Snipster has a Cut dead air option that removes long pauses and isolated um and uh using the transcript’s measured word times, never more than a quarter of a clip, and then moves the captions, zooms and effects onto the shorter clip. It does nothing when word times are only estimated. Audio cuts are hard cuts, so listen before you post.
