1) An iPhone 3GS is really awkward to record with for any length of time
2) My personal camcorder makes a really obnoxious sound when the auto-focus is operating
3) My personal camcorder has a stupidly short battery life.
The bts footage will be a challenge. I have a whole new respect for the people who shoot this stuff on a regular basis and make something useful and entertaining out of it. With the structure of a script or anything like that it’s hard to sort. Do I do it chronologically? That seems like the most likely way to organize everything, but I doubt it would be that entertaining.
