Every year a bunch of questions are posted about animation length, deadline, video format, etc.
Chief Delphi is a great place to get animation help, but don't rely on someone else's interpretation of the rules (myself included). Get it from the source - Autodesk.
PLEASE go to http://firstbasefrc.autodesk.com to register and download the rules! You'll need to register anyway to upload your entry and vote.
It's heartbreaking to work for 6 weeks on an great animation, only to have it disqualified because you never read the published criteria on FIRSTbase.
Good luck!
