Free FFmpeg Silence Removal Command Generator & Dead-Air Estimator
Customize your dB threshold and minimum pause duration below to generate an FFmpeg filter command—or skip complex terminal commands and audio desync bugs with CutFlow Pro ($49).
ffmpeg -i input.mp4 -af "silenceremove=stop_periods=-1:stop_duration=0.4:stop_threshold=-35dB:leave_silence=0.08,loudnorm=I=-14:TP=-1.5:LRA=11" output_clean.mp4
⚠️ Note on Raw FFmpeg `silenceremove`: Running `-af silenceremove` alone on an MP4 only trims the audio track, causing your video and audio to go out of sync unless you slice both stream timestamps frame-by-frame.
