How to use it
- Drop your clip.
- If it has several audio tracks, tick the ones to keep. Leave them all clear for silence.
- Run it. The video is copied, so it takes seconds and loses nothing.
- Save it.
Multi-track recordings
OBS can record game audio, your mic and Discord to separate tracks. Set that up in Output, Recording, Audio Track, then in Advanced Audio Properties. This tool lists each track and lets you drop the one you don't want, like a friend's voice or the music that would get the video claimed. It shows the track names when the file has them.
Questions
Does this make the video worse?
No. Video data is copied across untouched.
Which track is which?
OBS saves them in order: track 1, track 2 and so on. Most files have no track names, so check your OBS mixer to see which source went to which track.
