Hi David,
The issue is that the FCPXML describes the media as being lets say 2 streams each of 4 channels, but when we look at the actual essence the first has 4 channels and then the second has two. We would need the FCPXML in question and probably the asset r45.1.
FCPX should not be creating XML’s like this, it is not compliant with Apples own spec, but it does create them.
X2Pro may work as the code shuffled the channels regardless of where they were, so if it said there were 16 but only 12 were there it would take them and allocate them from 1 to 12. This shuffling was not correct as we were changing what should be where so we changed to the spec Apple told us to apply.
I will raise with the Product Manager and development and advise.
Yours Sincerely
James.
