Absolutely agree - video is not a replacement for being seen in person by the coaches, but at least in our experience so far that has been the tool to get the coaches to the field to watch the games, and when his video has been watched by most of this target schools which in most cases seemed to be the first step in the dance.
Also, if you happen to have an organization or coach who is effective in the social media space that can be huge. Our club director tweeted a composite tape of our attack and it got several hundred views, and out of the blue all of them were getting emails from schools who had never seen them play in person.
