Also the last Q/A which mentioned exporting in the Working with SMPTE-ordered multichannel files in Pro Tools article has been updated June 20 2019.

I don't know what kind of double-speak that tech is talking but the KB article we are all talking about is the one you linked to at the end just now. You can clearly see that is so in Paulo M's post earlier (post #3) and Tom Lowe's post (post #21) earlier. It was also wrong at the end of 2018 when we discussed it in this thread: http://duc.avid.com/showthread.php?t...light=Its2loud

And it was wrong.

They updated it today to where it is right. But previously it had the incorrect information and it has been that way for a very long time.

There's saving face but no one was confused between exporting and importing.

The internet never forgets:

Default Re: 5.1 file channel order

If you are referring to the last QA in the article ("Not at this time.") then yes, that was incorrect so was updated today. Our tech also added 7.1 info in the first QA pair. I guess it would have been more accurate if our tech said "Other than that last QA pair..."
Any other feedback on that KB article? Also, would it help to merge threads to bring this all together? Thanks.

Default Re: 5.1 file channel order

Merging would be good so this isn't rehashed a third time.

The one line in the QA that should be changed is this one:
Quote:
It is possible to export WAV files in SMPTE order at this time, but only files up to 5.1. Pro Tools uses the BWF Wave Extensible Standard channel order when exporting WAV files, which is the same as SMPTE order up to 5.1.
"Possible" doesn't really cover it. For BWF, 5.1 SMPTE order is the only way the file will be exported.

Right now it is open to interpretation when there is actually no choice.

Totally agree with Bscout. This has been the subject of so much pointless debate, occasionally verging on argument, when in fact it’s 100% clear, defined and non-optional.

Thanks BScout. You bring up a good point. Best to not leave it up to interpretation. I think it’s in Avid’s best interest to release a specific document detailing all the channel orders Pro Tools outputs for specific file formats and widths.

Completely agree!

Sounds like just removing that first sentence should address this concern, but please reply if additional definition would help. Thanks!

Striking the first sentence helps. The second sentence is convoluted in it's "A uses B when doing X and B = C therefore A uses C" approach.

So changing

to

Quote:
When exporting WAV files, Pro Tools uses the BWF Wave Extensible Standard channel order which is in SMPTE order up to 5.1.
is a more direct answer to the Q part.

Default Re: 5.1 file channel order

Jeffro,

One can further expand on that answer with....

“When exporting AIFF files, Pro Tools uses (insert channel order here) order up to 5.1 and when exporting Quicktime files, Pro Tools uses (insert channel order here)up to 5.1.

Then go on to detail 7.1 channel order.

Thanks.

What about changing the code so that users can choose what channel order they want to export to, despite the format? I think that it would make much more sense.
