I apologize but I cannot get OBS to give me anything usable. I tried converting the .flv files to .mp4s but that didn't work...I guess I don't have the program set up correctly because I got audio recording but no video, just a blank black screen. The music is there, but there's no video recorded for some reason.

Anyway, at this point, I feel like I have two options:

1. Return to using Screencast-o-matic.

2. Let someone else record the video, and simply continue to provide the combining service once they send me the raw video.

If there are any suggestions, I'm all ears.
