How it works
Three steps. No export. No leaving Premiere Pro.
Launch the CaptionX extension panel from your Extensions menu. The silence remover is built right in — no separate tool needed.
Choose your silence dB level and set a minimum gap duration. This tells CaptionX exactly what counts as silence for your recording.
Hit detect. CaptionX scans your sequence, finds every silent gap, and removes them all from your timeline in one click.
Who uses it
Any editor who records speech — interviews, podcasts, voiceovers, presentations — spends time cutting silence. CaptionX gives that time back.
Also included in CaptionX
CaptionX also includes AI auto captions in 57+ languages, filler word removal, and more — all inside the same Premiere Pro extension panel.
