I walked into a classroom the other night and saw a bunch of students pitching their short film with an animatic. As they talked about the different shots and how long it would take to shoot them, the instructor gave them feedback with additional things they didn’t think about. One of the team members jumped over to using this free program and adjusted the time on their project. It was simple and really useful. But the best thing about it is that is totally free.
So if you are planning on building a site with a bunch of people, this tool is indispensable.
