How this video muter works
Muting a video means removing its audio track so the file plays in silence. VimCut copies the video stream into a new file and leaves the audio stream out, so there are no settings to choose. Your original file is not changed.
Because the picture is copied rather than re-encoded, the video quality is identical to the original and the process is quick, even for long clips. It runs on WebAssembly (ffmpeg.wasm) in your browser, so the file never leaves your device. The output is an MP4 file. Muting is useful when a clip has background noise, an unwanted voiceover or music you cannot use. You choose the file, click Remove Audio and download the silent copy. Because nothing is encoded again, the result is ready quickly, and your original file with its sound is still on your device if you change your mind.
