what about batteries? video recording goes through batteries like you cant believe.lighting? what conditions will there be? usually video with dslr is used in intercut in weddings. meaning the idea is to shoot short clips with various angles and lenses so the editor has footage to make a highlights video. but since youre just there to document then you have to do a constant roll.
you will be using a tripod, im assuming? video head? ball head? and you plan on staying at the same position just change panning left/right to record accordingly? dont forget white balance.
I hope its not too hot because ive seen videogs who shot for max recording times and the camera shut down on them from overheating. im not certain it will, or wont. im just mentioniong things that can happen.
I dont know editing so cant help you.
you might consider posting to a forum I frequent
