I recently rendered out some footage from a shoot as 10 bit Uncompressed 4:2:2 footage out of Premiere pro CS3. The problem is when I brought it to another workstation to key out green screen, its unrecognized. I brought up quicktime info and the clips read "unknown" under codec. The computers I brought them to work on do not have CS3 they only have Pro 2. I am wondering where I can get the codec to play these files at the new work station otherwise I will have to re-render out the footage, which I am trying hard to avoid.
