So I was having issues for a short film release, it turns out that ProRes supports Multitrack audio with Mono/Stereo/5.1 tracks however I didn’t know how this should be handled.
After going through it again and thanks to the help from the guys over at the “Editores y Postproductores México” FB Group https://www.facebook.com/groups/editoresmexico/permalink/3844096602305717/?comment_id=3844284348953609
I managed to get it working.
Here’s the basic workflow:
I needed 4 mono tracks and 1- 5.1 track, the premiere export accounts for all tracks as 1 but when selecting type 5.1 for a multitrack it counts as 6 tracks so at the end you want to do a Multichannel 11 Adaptative Tracks Sequence.
Something like this:
Track 1 – Mono (Stereo Mix L)
Track 2 – Mono (Stereo Mix R)
Track 3 – Mono (M&E Mix L)
Track 4 – Mono (M&E Mix R)
Track 5 – 5.1 Multitrack (5.1 Theatrical)
Go to the new sequence dialog and under the tab “Audio Tracks” select “Multichannel” and number of tracks “11” (The extra track helps for premiere exporter to recognize the last track as 5.1)
Make sure you have 4 Adaptive tracks numbered 1, 2, 3, 4 and a single 5.1 track on the 5th track.
You should see something like this:
Now you have to make sure to click each “Output Assignment” and route each channel to its intended output, for example:
Track’s “Audio 1” Channel 1 goes to Ch.1 on the Master Track
Track “Audio 2” Channel 1 goes to Ch.2 on the Master Track
Track “Audio 3” Channel 1 goes to Ch.3 on the Master Track
Track “Audio 4” Channel 1 goes to Ch.4 on the Master Track
Track “Audio 5” “Channels L R C Lfe Ls Rs” go to Ch 5 to Ch 10 in that order.
You might notice that Channel 1 on every track is routed to Ch 1, 2, 3, 4 respectively, thats because as your input is a MONO track you have to tell Premiere that It’s channel 1 is the one to be exported.
Once you have your timeline with 4 mono tracks and 1 Surround track go to MOVIE/ EXPORT
Select ProRes HQ
Under Audio settings, make sure to map each mono output to a single channel and the last 5th track make it 5.1 with L R C Lfe Ls Rs mapping.
Once you’ve rendered your file, you sould have 4 mono audio tracks and 1 Surround 5.1 track on your .mov
