I am a high school wrestling coach and I am thinking about buying a new Ipad for many reasons, one of the biggest being that I could more easily film my wrestlers matches. An average wrestling match is only going to be 2-4 minutes but there are days where I might be filming up to 40 or 50 matches. I know there are a lot of variables but on average (just looking for an educated guess) what size will each of my films be? What size Ipad should I get (I really dont want to spring for the 64)? Is there a different solution for uploading these videos to a cloud or a way of quickly and easily getting them off the Ipad so it doesn't fill up as quick?
