Export a QT Prores 422 with 5.1 audio correctly mapped

Hi there,

I need to supply a QT file with 5.1 audio for a film festival (they don't accept DCP and I do not have the time to get a Blu Ray authored)

I have the QT 4444 master and 6 WAV stems.

Could someone please walk me through the correct setup to export this?

I have a few questions like;

what should my sequence settings be? (5.1 or multichannel?) Including how many audio tracks? are they mono or 5.1? how are they panned and assigned or are they all left as is? I have read conflicting information about this part.

in the sequence am i dropping in my tracks in this order;

A1: L

A2: R

A3: C

A4: LFE

A5: Ls

A6: Rs

when I output the sequence, I need QT Prores, so there is no Dolby settings in Audio settings.

Am I making an uncompressed audio file with the 5.1 mapping listed above?

I have no 5.1 monitoring at home, is there any way of testing that the mapping is correct? (I have DCP-o-matic, VLC, Resolve Studio 12.3)

I have to do this today unfortunately!

thanks in advance for any help!

best,

Chris

      In premiere, make sure you have each surround stem in a mono track and NOT

      a multichannel mono track.Otherwise, when you export the stem, the audio levels will be lowered considerably.

      New custom sequence, with multichannel mono audio tracks (6 total)

      important you choose multichannel and NOT 5.1...for some reason it lowers the audio volume on export.

      Then bring in each track in order of smpte specs:

      L

      R

      C

      Lfe

      Ls

      Rs

      Then go to the mixer window and pan each track. (click the 'L or 'R') for 100% panning.

      L

      R

      L

      R

      L

      R

      Also make sure you check each box (in the mixer)

      L & R is mapped to1 & 2

      C & Lfe is mapped to 3 & 4

      Ls & Rs is mapped to 5 & 6

      (this keeps them all seperated without combining them all)

      Once done, the audio track mixer should now look like:

      L (1&2)pan left

      R (1&2)pan right

      C (3&4)pan left

      Lfe (3&4) pan right

      Ls (5&6) pan left

      Rs (5&6) pan right

      Finally:

      Export the quicktime, in the audio options choose multichannel 24-bit. Your codec has to support this feature like prores or cineform.
