How do I get sound on the second instant of obs

[Daveasdf]

I want to run two instances of obs, one for the face using the webcam, and one for the screen. I would then use a video editing program to overlay the face on the screen recording, so that I can occasionally use the full face video, instead of always having it overlaid on the screen.

I was thinking I could sync up the two videos using the sound. However, despite both instances showing the mic input volume level going when I talk, only one of the instances records the sound.

I have to assume that this is because only one app can be using the mic input at a time. Is there a way around this, without having to invest in another mic? Would a webcam with its own mic input work for the one video, with the laptop mic forthe screen recording?

Why don't you create two scenes (within one OBS Studio instance)? One containing only the webcam and another scene with the webcam on top of the screen. Is there a specific reason to do the directing (deciding which shots at which moments) in post production?
