Rendering file w/ multiple audio tracks

Hello all,

Forgive me if this has been answered in the forums already but my search came up with no results.

I'm using Sony Vegas Pro 9 to try and render my project into a quicktime or avi with seperate multiple tracks so that I may eventually have it output by a tape house to a digibeta as:
track 1: composite picture
track 2: audio
track 3: music
track 4: effects
...so that the distributor can split up the elements and put on another language if necessary.

My problem is, when rendering into an .avi or .mov I don't ever see an option under the audio section to save as multiple tracks, only mono or stereo. On other file types, when it does have that as an option and I click "save settings" it tells me my project type doesn't support that, etc. etc.

Is this something that needs to be done within the render settings, the project properties, something on the timeline or each track's settings themselves?

I'm extremely new at having to do this multiple track export stuff, so any help or directions as to how I can do this would be extremely appreciated!

(I found an article on Creative Cow from someone having the same problem within Final Cut Pro. Maybe the solution in Vegas is similar? http://forums.creativecow.net/thread/8/1025064

Also, I should mention if it matters that I don't currently have a Pro version of quicktime, only the free version)

To take care of your audio issues, grab yourself a copy of Trackalizer from VASST.
It's free but you have to have an account there which is quick to do and spam free.

To render to multichannel you need to route to busses.
Then when you tick the Enable Multichannel... box you get another set of options to setup the buss to channel routing.
Then when you go back into the Audio properties tab you can select more than 1 stereo pair. You need to setup enough channels otherwise all you get is all the busses mixed into the one stereo track. The way the thing works is very confusing to say the least but it does work.

Thanks Bob. I think I get the gist of how that works. I'll try that out and see if it works for me. Thanks!

So, Bob, is the result similar to a multi-channel broadcast wave file but without timecode?

Yes.
I used it in earnest on a current project. I had two tracks of stereo from my R4 however of course simply grouping them does not ensure they will always hold sync if I manage to Ungroup them.

Rendering them into the one file means if I do Ungroup them and slip them I get the red Out Of Sync warning. Because I'm mixing them sample accurate sync is important.

However you can also do the same thing with AVI files which is what I think the OP is after. You can have an AVI file with a vision stream and multiple audio streams. Digital Betacam and HDCAM tape also supports this. Typically tracks 1,2 full mix, tracks 3,4 music and effects only etc.
