How to cut pauses and dead air from a video
Long gaps make a talking video drag. Here is a fast manual workflow in Cutline: find the pauses on the waveform, split the clip around them and delete each gap with the timeline closing up behind it.
Before you start
You need a recording with speech (a tutorial, an interview, a talking-head clip) and a browser with WebCodecs, such as current Chrome or Edge.
Cutline does not detect silence automatically, so this is a manual method. The upside is control: you decide which pauses to remove and which to keep so the speech still sounds natural.
Step by step
- Open the editor, drop the recording into the media library and drag it onto the timeline.
- Zoom in on the timeline (hold
⌘orCtrland scroll) until the audio waveform is easy to read. Pauses look like flat stretches between the peaks of speech. - Press
Spaceto listen. Put the playhead at the start of a pause (use←and→to step a frame at a time, or holdShiftfor a second) and pressSto split the clip. - Move the playhead to the end of the pause and press
Sagain. The pause is now its own piece. - Select that piece and press
Shift+Delete. The piece disappears and the clips after it move left to close the gap. - Repeat for the rest of the recording, then press
Spaceto review the result and export with⌘E(Ctrl+Eon Windows and Linux).
Tips for natural-sounding cuts
- Leave a short breath-sized gap, around a quarter of a second, instead of cutting speech flush against speech.
- If you hear a click at a cut, add a very short audio fade to the clip edge.
- Hide jump cuts in a talking-head video by changing the scale slightly on every other clip, or cover the cut with a text label.
- Made a bad cut?
⌘Z(Ctrl+Z) undoes it;⌘⇧Z(Ctrl+Shift+Z) brings it back.
