I'm not sure if that video would be that helpful for someone just getting started using the radio. Here are a few critiques:

For the entire video, your instruction was being over-talked by the enroute controller comm. Using your onboard video to provide examples of various comm situations may be helpful - trying to actually impart lesson material using on board video while you're also flying doesn't seem as effective.

You were essentially giving a CTAF lesson but you chose to do it in a completely unrelated environment while under ATC control in cruise flight. The one CTAF radio call example you included was very short and got cut off at the end.

You could probably wait on introducing information about ADS-B if you're trying to help a newbie talk on the radio. Some guys may not even know what you're talking about. If you are going to talk about that, I would suggest some form of visual aid to help the viewer understand the relationship between the CTAF radio call in your example and what they might be seeing on TCAS/ADS-B.

Finally, I think if you deliver your instruction in a more sterile environment it will be more effective. Perhaps shoot the lesson while still on the ground. Splice in cuts of on board video showing examples of radio calls in the specific phases of flight you're discussing.
