Sorry, I am not sure I understand correctly: If you change the value "0" for Video Line Map in a 3840x2160 file created with FFmpeg to "42", the file works with Avid Media Composer? > Perhaps it's not technically possible, but an option like > -keep_all_metadata would be very helpful in such case. Sorry if I was unclear in my first message in this thread: Just as FFmpeg is unable to "replace" streams, you cannot "keep" metadata.
