I was going to ask at what distance did you set your focus to? Also, was the video shot all at the same focal length? I'm setting up a 7D for u/w, I'm used to a video camera where it can be in constant focus, so here, the trick is to keep the distance constant, but you can't do that. Do you stop shooting, re-focus, then shoot again?
I assume the lack of sharpness is due to all the compression you had to do to get the video to fit inside three minutes, correct?
