i'm not quite sure i fully understand this... i feel like it's going to be 20-30 minutes of random edits with no flow whatsoever. even if your going to keep the same font the whole movie, the whole thing pretty much needs to me edited by just 1 person, everyone has their own different editing style and i feel like 7 different editors would not work at all. and also youre going to have all different types of footage too, FX1, vx1, and $200 shitty handycam footy do not look good all mixed together.
second is i'm really not sure who is going to send footy in.. almost every legit crew is saving their own footy for their own movie.. stept, ski block, NIG, 4bi9.. etc.
i'm not trying to bash this, just trying to bring up some possible flaws that need consideration. this idea has come up many times before and it's good to see that someone is really trying to run with it. good luck, and if it comes out dope then I tip my hat to you.
