I've used the Canon T2i for a couple of commercials. The leftover footage has been a great opportunity to really try out HD quality in editing. Here are 3 videos featuring most of the footage that I did and did not use for the last few ads I shot. All shot on the Rebel in 720 / 60p, Post, Slow-Mo, and color grading in Sony Vegas Pro 9.
