Rendering Multiple Clips
 

I have a single project, about an hour and a half long, with about 30 chapter markers. I want to render each region separately to make them web ready, as <region name>.wmv (or the appropriate format). Sounds like a good job for scripting? I'm a C# developer at Microsoft, but to be honest, I haven't looked at Vegas scripting yet, maybe it's time! Does Excalibur or similar already have this built in, by chance?

Tools - scripting - Batch Render

It's already built into Vegas Pro 8.
Tools - Scripting - Batch Render.
The option to render regions comes up when you run the script.

Ah, got it. I just learned the difference between a Marker, and a Region. I have chapter markers placed, not regions. So, any script to create regions based on markers??

Excalibur can convert the markers to regions for you.

If you don't have Excalibur and can't find a script to do this, double-click between each set of markers in the area just above the timeline and press R to create a region.

I knew I had one lying around on my hard drive somewhere :-)
Thanks to John Meyer for this script.

Copy everything below and save it as MarkersToRegions.js

MyRegion = new Region(RegionStart,RegionEnd - RegionStart,RegionName);
Vegas.Project.Regions.Add(MyRegion); // Add the new region
}

if (markerEnum.atEnd()) break; // If out of markers, quit.

// If last marker is equal to or beyond the end of the project, stop here.
if ( Vegas.Project.Length.ToMilliseconds() <= markerEnum.item().Position.ToMilliseconds() ) {
break;

function RegionExist(dStart,dLength) : boolean {

var fmarkerEnum = new Enumerator(Vegas.Project.Regions);

while (!fmarkerEnum.atEnd()) {
var fRegion = fmarkerEnum.item();
var fRegionLength = fRegion.Length.ToMilliseconds();
var fRegionStart = fRegion.Position.ToMilliseconds();

if ( (dLength == fRegionLength) && (dStart == fRegionStart) ) {
return 1;
}
fmarkerEnum.moveNext();
}
return 0;
}

I see Edward already answered for Excalibur but VASST Ultimate S Pro can not only convert the markers to regions but it can also do the batch rendering without the need to do the conversion at all. The batch renderer in Ultimate S Pro will render between Markers (as well as within Regions).
