It's not a video contest. It could be just like the YC application videos and the people at CodeYourIdea can screen it to make sure it's just a webcam and nothing car salesmanish. I don't know about other people, but I would appreciate an introvert who could still decently communicate as I would intuitively translate that into intelligence. I get suspicious when the person is a smooth fast talker.

Plus I think the video would be a really big deal for first time solicitors for code projects.
