Using silence auto-cut
Mark In/Out, analyze, review, apply: how the auto-cut workflow is designed to be used.
Silence auto-cut removes dead air from a range of your timeline with ripple deletes, so everything downstream slides up and stays in sync.
1. Mark In (I) and Out (O) around the section you want to tighten. The extension only ever touches the range you chose.
2. Click Analyze. The audio in the range is scanned locally for silences; nothing is uploaded.
3. Review the proposed cuts. You can adjust the silence threshold and padding (how much breathing room is left around speech) and re-analyze until it looks right.
4. Apply. The extension performs ripple deletes on the timeline. It's a normal Premiere edit, so Undo (Ctrl/Cmd+Z) reverts it like any other action.
TIPS - Leave a little padding (100–200 ms) so cuts don't feel clipped. - Work section by section rather than the whole timeline at once. It's faster to review and easier to undo. - Duplicate your sequence first if you want a belt-and-braces safety copy.
