There's no guarantee the 2013 rules will be similar, but here are the 2012 rules:
http://students.autodesk.com/ama/ori...es_Jan2012.pdf
Key points are:
- You must use Autodesk software (3ds Max, Maya or Softimage)
- 30 seconds or less, not including title screen or credits
- 1280 x 720 resolution, 24 frames per second
- File must be H.264 or MPEG4 QuickTime format
- They have very specific title screen and file naming specs.
- You also have to create and upload a storyboard and a still frame JPG
Ideally Autodesk will post the new rules the same day as the Kickoff (Jan. 5) but they might be a few days late.
