Thanks for the recommendations, I'll take a look at them.
For PIP I simply used Quicktime (the one that comes with Mac). I opened a "New Movie Recording", but didn't hit record. Then I resized the window and put it where I want. Finally, I open a "New Screen Recording" that captures a 1080p portion of my window. So, Quicktime is recording itself.
I also tried this with recording turned on in both windows, and it works fine. That would allow me to switch back and forth between screen and face in editing, if I wanted to.
