Long pauses and dead air make a video drag. Descript can shorten the gaps between words across an entire recording automatically, and clean up stretches of silence, so your final cut feels tight and energetic. This guide shows how to do it without making speech sound rushed.

What you need

A Descript project with a recording that has slow pacing or long pauses
A target feel in mind (snappy social clip vs natural conversation)
A few minutes to review the result

Step 1: Open Shorten Word Gaps

Go to the Edit menu or the magic tools panel and choose Shorten word gaps (sometimes called Tighten or Remove gaps). This tool finds silences between words and trims them to a length you set.

Shorten word gaps

------------------------------------

Shorten gaps longer than: 0.5 s

Down to: 0.25 s

Scope: ( ) Selection (x) Whole project

Found 64 gaps to shorten -> saves ~38 s

[ Apply ]

Gaps longer than the target are trimmed across the whole project.

Step 2: Set a sensible gap length

Choose the threshold (which gaps to shorten) and the target length (how short to make them). Trimming gaps over half a second down to a quarter second is a safe default. Going too aggressive makes people sound like they are gasping for air.

Do not remove every pause

Some pauses carry meaning, like a beat before a punchline. If you flatten all silence, the delivery loses rhythm. Keep a natural floor (around 0.2 to 0.3 seconds) so speech still breathes.

Step 3: Apply and review

Apply the change and play through a few sections. Listen for places where the cut sounds clipped or rushed. Where it does, you can locally restore a pause by editing the transcript at that spot.

Step 4: Remove leftover dead air at the ends

Recordings often start and end with silence while you reach for the keyboard. Trim those by deleting the empty space at the top and tail of the transcript, or by trimming the clip edges directly.

Tighten summary

Shorten word gaps applied: whole project

64 gaps shortened, 38s removed

Head silence trimmed: 2.1s

Tail silence trimmed: 4.7s

New runtime: 9:41 (was 10:26)

Result: a ten and a half minute recording tightened to under ten minutes with snappier pacing, while still keeping the deliberate pauses that give the delivery rhythm.
