I'm not sure you're on target here. Your describing everything that PG says not to do in the video: "The video should contain nothing except the founders talking. No screenshots or postproduction wizardry please; we don't want this to turn into a video making contest. If you're going to spend time making something cool, put it into your demo/product. Please do not recite a script written beforehand. Just talk spontaneously as you would to a friend. People delivering memorized speeches (or worse still, text read off the screen) usually come off as stupid. Unless you're a good enough actor to fake spontaneity, you lose more in the stilted delivery than you gain from a more polished message."
