I need to determine which file format to master my film to. I am aiming toward film festivals. In Final Cut, the files are currently 422 Prores HQ. I would appreciate if someone could point me toward some literature on the topic so that I can do some research.
I always make a master of the file in the format I worked in. So in your case, ProRes 422. I go to File, Export, Quick Time Movie. Make sure it is set to Current Settings and the Make Movie Self-Contained check box is checked.
With that file you can compress it for DVD, Blu-ray and DCP if needs be. You can also look into backing it up to tape but that becomes pricy. Best of luck.
Well, the highest is uncompressed/animation but you won't find any noticeable difference in quality with prores HQ, and you will will find a noticeable difference in disk space. So, just stick with Prores 422 HQ
