I found it. When I wrote this I was learning the Sony object model so it is likely kludged up but it did work for what I needed. It worked at the time but I haven't used it since so YMMV.

Name the first marker of each clip the name of the output file. If you do not want to render a section name the marker 'del' and there must be an end marker named 'end' (without quotes).

ie:
Marker 1) ant1
Marker 2) del
Marker 3) ant2
Marker 4) ant3
Marker 5) del
Marker 6) ant4
Marker 7) end

If you want to render to a different template, change ' rendname="DVD NTSC" ' to whatever template you want. If not mpg then you will have to change the corresponding entry of
var renderer : Renderer = Vegas.Renderers.FindByName("MainConcept MPEG-2");

To whichever is appropriate. That may also cause you to change the .mpg extension reference also.

Ed may already have one of these or he or someone with more experienced with scripts can probably clean this up.

FWIW.

If you have Ultimate S or Excalibur you can also do this by making a Region of each segment and rendering Regions. You can choose to make the name you give to the Region come through into the name of the Rendered clip.

There may also be a free script that renders from Regions - try VASST.

Vegas 6 & newer (maybe 5, never owned) includes a region rendering script.

> If you have Ultimate S or Excalibur you can also do this by making a Region of each segment and rendering Regions.

Actually, in Ultimate S Pro 4.0 it will render Markers too so you don't need to do anything like create regions. You can download a fully functional 14-day trial of Ultimate S Pro and use it for this purpose. Use the Render tab, check Project and press the Markers button. It will render the timeline between the markers in any number of formats you choose using the marker names as the filenames.

Here's my revision of the batch script supplied with Vegas. You first create regions around each segment of the timeline you want to render. Then, you run this script and select which render templates you want to use. Each region will then be rendered with each template. Thus, you can choose one of the MPEG-2 templates and also one of the AC-3 templates and render both the video and the audio for each of your regions.

This link good for seven days:

Batch GUI Script

This script works with Vegas 7.0d. May also work with other Vegas versions.
