I am working with original 2K (2048) ProResHQ files with a delivery requirement of the highest quality (resolution/color) least compressed file for making a 2K DCP.
In order to output a file for the DCP with highest quality and least compression, what codec would you recommend? The main choices seem to be HEVC or AVC by Sony or Magix, or am I missing something? Do I assume constant frame rate is better than variable? higher profile better than "main"? is there a maximum bitrate best suited for the recommended codec(s) given that ProRes HQ is something like 200+ Mbps, and my ProRes assembly is about 62G?
The online manual is vague about the cost/benefit of some options: more or less slices, two pass VBR vs one, number of reference frames, what "encode quality" slider does to the picture and file? Rendering time and size is not an issue.
Many thanks for all suggestions!
