Video - depends on the aircraft and the mission. I was involved in a filming project a few months ago where we used a Robin R2160 to shot aerobatics video. This is a two seater with a rather high baggage shelf behind the seats. We used a stand made from one of those steps you use to step into your caravan, strapped it down real tight with ratchet straps and used that to mount the cameras. We then secured literally everything with tie-wraps. You really need something solid, a clamp or stand or something like that to mount it to an airframe part. Use a camera with a wide lens so that it can see the instruments in addition to the outside world through the front windscreen. We also had a keyhole camera mounted on the windshield next to the compass, pointing backwards, with the recording unit mounted in the back on said stand.
Audio - the audio output that goes into your headset is a regular DIN something so if you arrange a splitter cable for a regular headphone you can use that for audio in into the camera. Not much adjustment needed.
Personally, i wouldn't bother for a PPL lesson. It took us a good three-four hours to get everything mounted and set up.

Reason: Clarify that this was for aerobatics
