the idea of having a film contest is cool, but I dont think it would really work.  Not to hate or anything but, from a filmers perspective that would be absolute hell.  I have been at boreal for opening day for the past 8 years running and the number of people that show up is absurd.  All shots would be filled with people, equipment would get run over, and truthfully, all shots would end up being follows... not the most exciting nor professional especially considering it is a film contest.
The fix?  have the best trick one day and the film contest the next, and give the teams a separate time to do their thing.  The number of teams entering will probably be lower than the number of individuals, thus spreading out the chaos on the opening day "patch"
just something to think about, because I dont want to be trying to film an edit for a video contest and not be able to do it properly.
