Wouldn't just turning off (muting) the tracks you don't want work?

Arthur, you can do it that way but Trackalizer is SO much easier. Run it and every audio track is exported separately. You have other render choices in there too.

standard script Render Audio Tracks should work exactly as you need

I downloaded the Vaast script and it does the exact same problem as the script I mentioned in Vegas. I don't think anyone is understanding my problem. EXAMPLE:

Track 1 is 3:35
Track 2 is 1:00

When the script renders it makes track 2 to the same length as track 1

Is it possible to have Vegas recognize the last audio media in a track and end the render there?

I understand exactly what you want. I modified the default "Render Audio Tracks.cs" script that ships with Vegas so that the length of the audio file rendered for each track equals the length of the audio on that track. If the audio doesn't start at timecode 0, it will start the render wherever the first event on that track starts. Thus, there will be no silence at either the beginning or the end of the rendered files.

Copy this script to Notepad, and then save it with the extension ".cs". Make sure to NOT copy "code block."

Hello John,

It works!!! I had to select LOOP REGION.
How do I make this code be a permanent part of the tools/script?

Thank you so very much!

Cheers!

Oh yeah, you are right. I completely overlooked the fact that the script won't get to my code unless you already have a loop region selected. I could change that by changing one line, but since you figured it out, I guess you can just live with this flaw.

I don't have V13 on this computer, so I don't know the exact steps for making this script directly accessible (they changed a little in the newer versions of Vegas), but in V10 you go to the Options menu and then select either the Cutomize Toolbar or Customize Keyboard options. This lets you put this script either on the icon toolbar or assign it to a keyboard shortcut. Sony degraded this ability by only allowing some things to be assigned to the toolbar, with the other things now having to go onto the playback toolbar. Grumble, grumble ...

If you put the script into this folder:

C:\Program Files\Sony\Vegas Pro 13.0\Script Menu

it will show up directly in the Script menu.

In earlier versions of Vegas you could actually change that script folder to a much friendlier location that didn't require you to muck about in the Program File area, but Sony removed the ability (via a hidden preference) to do this in Vegas 10, never to return. At least they brought back the ability to open a Veg file by dragging it to the Vegas title bar. That was removed for at least three iterations.

Grumble, grumble ...

"Is it possible to have Vegas recognize the last audio media in a track and end the render there?"
Maybe you don't understand the concept of the TIMEline?

Your tracks are set up relative to others on a time line so that they play at specific times. Those times are relative to the positions each track holds. If you have an audio track set up to start at the 3 minute mark then clearly you will have 3 minutes of dead space in front of that track. That occurs so that it stays relevant to the timings on the other tracks. Given the fact that this is indeed the primary job of the TIMEline, there is no easy way to skirt it.

You could reposition all your audio tracks into a better pattern and the render. Just don't save the project that way. Once you're just close and recall the original project.

Or you could render one track at a time (use loop region and mute the other tracks).

Maybe you don't understand the concept of the TIMEline?At the risk of being slightly impolite, perhaps you don't understand that my script does exactly what the OP requested. His problem has been solved.

Rob, the problem was solved by Johnmeyer's AWESOME script. This saves me so much time for I'm editing all the chapters in the bible. Each project is by book.

Cheers,
Randini

Hi guys,

I have used the TRACKALIZER in past projects (best name ever,,,) - however, it does not work in Vegas Pro 13. Is there a new version? Is there a modification I need to do? Any help appreciated...

T

Is Render Audio Tracks script (under Tools > Scripting) the same as Trackalizer ?

This script worked great for me....Just wanted to say thanks John.....
