Of course, before posting, I hit the docs. No dice. There are vague references to 5.1 audio tracks, here and there... I guess to assure us Adobe knows they exist because today they're everywhere.
I have to deliver a ProRes 4444 master with 5.1 mix track to a DCP outfit for an upcoming festival screening. Should be simple as soup, right?
Using V 23.4 (Build 56), under Ventura 13.4, on an M1 Ultra Mac Studio desktop beast with 64 GB RAM, and lotsa GPU power.
Well, in Export mode, neither "Match Source" under the Video Settings popup, nor "Match Sequence Settings" selection in the Format menu work! Nada!
I get a stereo L,R track as result, which seems to echo my track mapping of the 5.1 for monitoring on stereo hardware- which works well, but that shouldn't affect exports, right? Otherwise, I'd see something to cancel out the track mapping, something unusual, convenient, like, oh, maybe a chekbox labeled PASSTHROUGH EXISTING SEQUENCE VIDEO AND AUDIO FORMAT FOR EXPORT, right? Right?
This would be very helpful during deadline episodes.
Now to really twist the issue... I notice I can export the 5.1 if it's part of an H264 timeline export. So I'm not expecting PPro to peform functions it can't manage. I do a Get Info (Command-I) on the resulting MP4 QuickTime Player window and it reports all six tracks are a part of the file. But this is going to a DCP packager who works with highest resolutions and a full surround track. What am I doing wrong?
I'm running out of hair to pull out. Please help save Uncle Loren's hair.
Best as always,
Thank you Meyer PJ. Tutorials like that, 5 years old, are exactly my problem, it doesn't relate to current versions.
But it provided clues, and eventually I nailed it!
