I started a project getting 35mm telecined to PRORES HQ format to use on FCP, however i am forced near the end of my project to export my files to a windows compatible format (since prores is proprietary). It is my understanding that prores is 10bit compressed, and i tried exporting to uncompressed 10bit, but premiere did not accept the file, it would only accept 8bit. Im trying to find a codec that will minimize the quality loss but i dont see any codec that can do so. I currently having to jump between after effects and premiere, where either program will accept some prores files and not others, and there doesnt appear to be any pattern why.
So basically its already been color corrected initially in telecine, and fx are done afterwards, but since is having to had the source files changed from 10bit compressed to 8bit uncompressed. It works, so i cant complain there, but at what cost?
