Question / Help Lagging multicam video

[ogmaster]

I'm doing a webshow with four Logitech webcams. While the first cam's syncs up with the audio, once I switch cameras, the video starts to fall behind the audio. I saw some people have issues and they talked about delaying the mic, but I don't see the option in the Mac version of OBS. Should I record the audio separately and trying to sync it up? Any help is appreciated - https://youtu.be/rHFjqrdXFX0?t=392
