This IS the Avid L2: Re: [Avid-L2] Surround QT ouput

Actually, the Reference part is no longer necessary in v7, as you can export to QT using Direct Out in the Audio tab of the QT Export dialogue box.

But of you export Direct Out, the tracks will not be labeled, they will just be a bunch of tracks.

MC also allows for Surround 5.1 or 7.1 QT exports, so if you were able to bring it in as a 5.1 track, you could just export it as 5.1 to QT (it will indeed be exported as L,R,C,LFE,Ls,Rs, which is called SMPTE order).

.....BUT......

The bummer is that 1. MC won't allow you to route the 6 separate tracks to the appropriate buses of a 5.1 output. You can pan each track, except for the LFE track: you cannot route the LFE track to only the LFE channel.

Also, MC won't recognize the track name suffix that Pro Tools gives (Name.L.wav) as being part of a surround pack.

The workaround I use:

Rename the source tracks:

Name.L.wav becomes Name_1.wav
Name.R.wav becomes Name_2.wav
Name.C.wav becomes Name_3.wav
Name.LFE.wav becomes Name_4.wav
Name.Ls.wav becomes Name_5.wav
Name.Rs.wav becomes Name_6.wav

Choose File->Import, go to Audio import tab, choose 'Autodetect monophonic groups', and set the multichannel assignment to 5.1 SMPTE. Select the renamed files. They will now import a single master clip, containing 6 tracks, treated as a 5.1 SMPTE clip. (The trick here is that this feature was designed to recognize multi-mono BWF files from sound field recorders, which label their separate tracks with the _1, _2 etc suffix).

Add this mix to the sequence. Open the Audio Mixer. To the top left, set the sequence to be 5.1. Output can be stereo for now (unless you have 5.1 monitoring on your MC). Check the sequence for sync. MC will mixdown to LoRo (stereo) on the fly for you.

In the top left of the Audio Mixer (or Audio Project Settings Output tab), set the system output to 5.1 SMPTE.

Choose File->Export, click the audio tab of the QT export settings and set it to 5.1.

This is the way I make QT Same-As-Source Quicktimes with 5.1 SMPTE ordered sound. You will notice that if you open it in QT player, it will have the tracks labeled correctly (L/R/C/LFE/Ls/Rs). It also means that any other encoders (QT Pro, Squeeze, AME) will treat it as a 5.1 source.

Hope this helps,

Job
