Re: 5.1 file channel order
The request has been made to update the Avid doc and it is being moved up the food chain.
As far as Bounce to Quicktime goes, I cannot confirm nor deny which order the file is in for an audio only .mov file from PT. Although, I suspect that since .mov is simply the container and the codec of the audio is still bwav inside the container, the order is still SMPTE. I have exported 5.1 Video Quicktimes from Pro Tools and I believe the order was SMPTE. Either way, this is not how I make my deliveries for Netflix. I export mono wavs from Pro Tools and then open them in QuickTime Pro 7 assigning each audio track to the correct channel and saving as a .mov. This horse is really dead but somehow it wants to keep coming back to life. |

I thing is simpler that exporting as mono files from PT, as I need to open them in QT anyway and add the stereo mix. Sometimes when using mono files, I do it in FFworks, I prefer the GUI to QT7

If you choose a SMPTE out path in Settings/I/O/Output tab, you should get a corresponding SMPTE internal bus. It all starts here. What´s the point of having your session in Film mode if your exports as interleaved go out in SMPTE and QT in Film?. It doesn´t make sense IMHO.

But the workflow may be different and that may lead to different user experiences, that´s all.

Re: 5.1 file channel order
Paulo, I don’t think it’s changing the physical channel order when you re-map in Quicktime. You’re only changing the metadata header info for the .mov file. The order is the order. So, if you’re re-mapping the metadata channel order of a file that’s already in a SMPTE order, all you are doing is changing the labeling. Therefore the header info will wrong compared to a the channel order if you think the file is FILM order but is actually SMPTE order. This is what happened to me. However, I can’t see your workflow so this might all be bunk.

Also keep in mind, the path order preference you set in the Output tab, is only the preferred default order of any new output path you create. Nothing more than that. |

Re: 5.1 file channel order
OK, so for the sake of clarity, I did some tests and found why I was right and wrong at the same time.
I generated a 5.1 track in Film Mode with pink noise, having the center channel higher in level than the other channels and the Lfe even lower, just for visibility purposes. I exported and also bounced the same track to both Wav and QT (.MOV). Then I imported the files into Izotope RX to check. RX doesn´t order files, you just choose the layout(film or SMPTE) for display purposes. To those that said that PT always exports SMPTE despite the AVID documentation stating otherwise, you´re right. All bounces and file exports to Wav were SMPTE. The bounce to QT was also SMPTE. But, if you export (Com/Shift/K) to QT, the resulting file is Film mode. And this is my workflow. I always export(not bounce) to QT, then re-arranje the tracks in QT and export as new movie with the right order. QT and as I mentioned before, doesn´t recognize the right order, just thinks is SMPTE, even when it´s not. Here´s some screenshots: 1-Importing of the file exported to QT into RX. Is Film mode: 2-Re-mapping of audio channels of the file in QT to export as new movie: 3-Resulting re-mapped file imported into RX and now correctly in SMPTE: So, because I always use this method, I was right in saying that PT exports in Film Mode, but only when exporting to QT. This is my workflow. Using other methods, I agree and was wrong, is always SMPTE. I hope this clarifies the issue. Only hope that AVID corrects the info and mentions that when exporting to QT, there´s a flaw (or not).

Re: 5.1 file channel order
After a couple of members requested Avid to look into issues raised about the KB article one of the techs pointed out "That KB article is not wrong because it's not really about EXPORTING - it talks mostly about importing, display order (on the timeline), meter order and audible channel output order. When exporting there are various factors that dictate the channel order of the resultant file - for example, exporting as AIFF will result in a different channel order to exporting as WAV."
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. Andrew |

Re: 5.1 file channel order
Great! Glad to know it’s been updated.
Maybe it would be a good idea for Avid to put out a tech document specifying channel order when exporting various types of file formats. This would be helpful to many. |
