I am brand new to OBS and would like to know how to set up for my use scenario. I would like to interview someone over live video and be able to start and stop video so that both the guest and myself can talk during a video pause. The final product would be a video including 3 components: 1) Myself, 2) my guest and 3) my screen share with a video. Same with the audio streams. I am brand new to this, so if you could let me know both hardware(Windows based) and software. Thanks!
