It's truly pretty amazing how much mileage a kid could get learning to shoot and edit video with
just an iPad or iPhone. Sure, the editing will be really awkward and the full range of effects and such that one would have in Adobe on the desktop won't be there, but hell, when we screwed around shooting videos as kids we had a big-ass camcorder that shot terrible video in 4:3 and in-camera editing/fx and that was
it. Maybe some really, really painful editing that would make quality way worse and take forever, if you could get ahold of two tape decks your parents didn't mind you screwing around with.
You can achieve more focused practice on shot choices, lighting, and cut timing on you parents' old, handed-down iPhone in a weekend than we'd have managed in a whole Summer with what we had. Got a buddy or two with phones or tablets, then you can probably manage multi-camera shooting (sure the picture characteristics may vary noticeably, but come on, this is still amazing) and ship the footage between devices in minutes. And once you get decent at it, the end result might even be almost watchable, instead of muddy garbage, and you can share it with the whole world with a few taps. I mean, damn.
