I'm looking for some guidance on how to do this somewhat unusual project:
I'm making a piece to be displayed on Blu-Ray with 7.1 surround audio.
The video doesn't even matter, in fact it would probably just be a black screen.
Now, according to the FCPX doc, 7.1 should be possible: https://support.apple.com/kb/PH12575?locale=en_US
However, I don't see any options for 7.1 anywhere.
In fact, when setting the project audio to "surround" (in the project settings), it only gives you the 5.1 options in the audio channel configuration. (No left-back and right-back channels).
Has anyone ever tried this?
Maybe it's a matter of exporting multichannel roles?
Or perhaps this is more easily done in compressor (although I'm not sure how)
So, ANY info about working with 7.1 in the FCPX / Compressor ecosystem would be much appreciated.
