[FFmpeg-user] ProRes422 with 8 audio tracks converted to mp4 -- muffles audio 4

[Harvey Pikelberger]

Carl, thanks for your feedback.  Very helpful.

RE "The audio configuration of your two input is very different..."
Is the issue that the ProRes is encoded 7.1 -- or -- that it's not 7.1 but FFmpeg is interpreting as such?
Adobe Audition & Premiere appear to interpret ProRes file's audio as all mono tracks, not surround.
