Real simple task: add 1 audio track in any format (uncompressed, AC3, Lossless, etc) to a Prores 422 video file (.mov).
I tried all different Matroska muxers... no luck. I thought Subler could easily make an mp4, but no... (I am aware that some files require 64-bit). FFmpeg fails to make AVIs out of them.
My only solution so far is to add it in iMovie, export to uncompressed video, then re-compress into Prores. This works OK and retains surprisingly good quality, but it's a colossal waste of processing for what should be a simple task....
