This was the closest topic i could find to my question.
If I have a 10 track ProRes supplied to me of a feature and tracks 1 6 I know are the 5.1 but they have nat been named in QT. When I import into FCPX it just sees 10 mono tracks. How can I tell it which are the 5.1. There are not the normal option you get if you bring in say 6 tracks and it suggests 5.1 and stereo.
I need to drop the 5.1 into a timeline and edit. I've not managed to work it out.
