Filmers Program

Football coach here looking for ideas and suggestions about improving our film program with students. Our HC isn't willing to pay parents to do Friday film so that's an idea thats out of the question at this point.

What kind of systems or perks do people use to keep student filmers involved and accountable to show up? Does anybody use a rotating schedule so they don't have to film everyday? We utilize practice film and obviously game film. 

Any help would be awesome!
