Watching yourself on video is always interesting. I do not however believe in rehearsals, unless it's training, not rehearsal. Getting better at talking is good, but being good at talking is actually more about listening, you have to adapt to the person you are talking to. Nothing is more annoying then a "on track" sales pitch. Then send them a video instead. Unless it's some kind of live performance.
