Some things just don't work very well with words. I just finished a diagram of the audio path of a rig that I'm building on Linux, and attached here for reference; maybe you could do the same for your rig(s)?I am honestly not sure what terms apply to what I want to do. I think I understand, but let me just tell you what I would like.
1) For tutorials I want to record my screen and my voice, which should be easy. Video and one track of audio.
2) For tutorial streams I will want to record my screen, my voice, and maybe a separate audio track for music. I would want both of the audios on separate tracks so I can adjust them as needed.
3) Then there will be gameplay videos. For that I will be doing both PC gaming and console gaming. I will want the capture from the console video (and that will have the game audio with it I would think), and my voice on another channel. That way I can adjust them separately in Premiere Pro as needed.
3a) For PC gaming I would capture the screen and the game audio and have my voice on a separate track.
4) They will probably be gameplay streams as well with the same goals as 3 and 3a, but with the idea being the ability to adjust in real time.
Thank you.
Mine has a common theme with variations, so it worked to use an overall diagram with certain parts disabled for different uses. You may or may not be able to get away with that; don't try to force it.
OBS can have completely different settings and content, in different Profiles and Scene Collections, so that can be an option too. I use that for the Master and Slave copies of OBS on the same machine, as shown in this diagram.
