Here's a 5.1 export viewed in QT7Pro so you can see channel order. Clearly SMPTE and not film. Avid has it wrong in the FAQ
QT7Pro will show Film order if it is received that way (and you can change order from the area I'm showing if you need to change a file.) There is no bias in QT7Pro toward one order or the other.

Ah, glad you mentioned this, because here´s precisely where things go wrong, again, based on my experience.

QT is in fact expecting an SMPTE file order. The order that is visible on your QT screenshot is actually not showing what QT detects, but the way "it expects it to be". But it´s still Film order as exported from PT. The first time we did it for Netflix, it got rejected because channels were in wrong order, guess which...

So, you need to re-arrange the order manually on that same menu and then export as a new movie.

Steps:

1-Export to QT from PT. Your channel order is going to be Film.

2-Open in QT 7 and go to Movie Properties.

3-Re arrange the SMPTE order shown to Film which is what in fact it is.

4-Export as a new movie(.mov file). Make sure you export settings are set to Movie to Quicktime Movie. Before exporting, you will also need to go into Options/Sound Settings and choose the apropriate SMPTE channel order, bit rate and FS.

Then you´ll get the right SMPTE order on the new re-mapped .mov file. You can then add your Lt Rt which is basically a stereo mix with it´s channel names renamed from LR to Lt Rt, again done on QT. Then you save it as a self contained movie and voilá. Film order exported from PT, re-mapped into QT and exported as SMPTE.


So, I still think that the AVID doc is accurate and up to date. If it´s not, it would be interesting if someone from AVID could explain why is not and correct it as should.
