you can record within matinee, the problem is that it needs much power and stores incredible high amounts of data (a HD video is about 1-5 gb/ 10 seconds in my cases) so i think it would be easier to somehow record what the player is / was doing and replay this in the actual scene if you want to watch this “movie” in game.
Thats the way from GTA IV and V and some other games with capture function.
