There is a setting, "Mute Recorded Audio" you can enable on ScoreCam.
There are also many tools you can use to remove audio after the fact. iMovie should be able to do this.
Avidemux is a free tool and, once you figure out how to use, it's really fast (passthrough): https://www.fosshub.com/Avidemux.html (May need to look here for the latest Mac version: https://www.fosshub.com/Avidemux-old.html)
Handbrake is a free tool as well but does not appear to have a passthrough option and can be really slow to re-encode the video (link: https://handbrake.fr)Tags: audio, settings
