Built for dead air and long pauses
Use the video silence remover for podcasts, interviews, lectures, webinars, tutorials, screen recordings, and talking-head videos. Red waveform regions show the pauses that will be cut, so you can adjust the edit before encoding.
Need a simple start and end cut instead? Try the video trimmer. To extract only the soundtrack, use the audio extractor.
Need silence removal across a video library?
Cutsio can automate silence removal, transcription, visual search, and collaborative review across your footage.
How do I remove silence from a video?
Choose a video with audio, let the slicer analyze its waveform, then adjust the threshold and minimum pause. Red waveform regions identify the quiet sections that will be removed before you export the shortened MP4.
Can I remove pauses from a video without uploading it?
Yes. Detection and encoding run in your browser tab. Your video is not sent to a server.
What does the silence threshold control?
It defines how quiet a window must be before it is considered silence. Start around -35 dB for spoken audio and adjust using the waveform.
Does the output keep video and audio synchronized?
Yes. The slicer exports an MP4 that keeps the video track and replaces its audio with the shortened, synchronized track.
