CaptionLayer auto edit

Automatic video editing: remove pauses and add captions

CaptionLayer can trim long silences, add gentle zooms and generate styled captions in the same workflow. Auto edit is optional: choose it in the studio before processing your clip.

What auto edit does

• Shortens long pauses. Cuts require confirmed audio silence and must not overlap recognized words. Small margins around cuts help preserve natural speech.
• Adds gentle zooms. Occasional centered zooms add visual emphasis to the existing footage.
• Keeps subtitles in sync. Caption timestamps are adjusted after cuts. The MP4 and exported subtitle files follow the edited timeline.

How to automatically edit your video

1. Upload a clip. Open the studio and choose an MP4, MOV or WEBM with audio, up to 500 MB and 30 minutes.
2. Choose Auto edit. Select Trim pauses & add zooms, then choose the style and placement of your captions. Leave Captions only selected to keep the original pacing.
3. Process and review. Select Edit & caption video. When processing finishes, play the result and check the cuts, framing and transcript.
4. Export. Download the captioned MP4 and synced SRT, VTT or ASS files. If you prefer the original pacing, open the caption editor, uncheck Keep auto edit in the next render and render again.

When is pause trimming useful?

It can help with talking-head clips, explanations, tutorials and short social videos with gaps between spoken phrases. Review the result before posting: a deliberate pause may be part of your delivery, and centered zooms can change the framing.

Does it remove spoken content or generate new footage?

This version preserves spoken phrases and edits your existing footage. It does not choose which arguments to remove, automatically turn a long recording into highlight clips, add B-roll or add sound effects. Background music or noise can prevent a gap from being detected as silence.

Do subtitles still match after cuts?

Yes. CaptionLayer recalculates the caption timings for the edited video. The original upload and editable transcript retain the source timeline so that a new render can restore the original pacing.

How are processing minutes charged?

Minutes are based on the original clip length, rounded up to the next whole second. Trimming a two-minute source to a shorter video still uses two minutes of balance. The first two re-renders of the same clip are free under the existing re-render rules.

New accounts receive 3 free minutes. Choose Mini or Creator for one-time processing, or Publish or Studio for monthly minutes and automatic social publishing. See pricing for current top-up packs.
