Now, when it comes to audio capture, things get tricky.

This can be helpful when you have to get an application set up or you need to tweak something in OBS while you're recording to avoid seeing the tunnel vision of videos inside of videos inside of videos you see in the image above. If I want to hide everything for a moment, I can use the Control+Command+J quick key to display the background image full screen above everything else (since it's the first source listed) (+H to hide again). In this mode, I've resized the video window to be smaller and have the Display Capture source beneath it so it shows up as the background. The picture-in-picture mode shown below is useful if I want to show my desktop as well: To start recording I use Control+Command+R (T to stop) and to switch between scene 1 and scene 2, I use Control+Command+1 or 2. I also have various quick keys set up in OBS as you can see here:

Because it comes last, the video shows up on top of it. One is my computer camera's input, two for sound which I'll explain later, and the one at the bottom is for the image I want set as my background. You can see from this screenshot how I have multiple sources configured for that scene. I also have OBS ( Open Broadcasting Software) configured with two different 'scenes,' one for picture in picture screen sharing and one for talking directly to the camera. This is the green screen kit I show in the video:
