In this thread [Link=http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=4&MessageID=859639] requesting ideas for the debugmode frameserver, Johnmeyer wrote:
"1. Incremental render. Vegas provides "smart rendering" for a few formats, but even for those formats (like DV AVI), it never provided the ability to easily update an existing render.

The idea would be that you could simply create a region around the section that you have changed, and you would ask to render that, and that newly rendered section would be "spliced" into the existing rendered file. I do this all the time, using a variety of external tools, but it sure would be nice to have it done automatically. You'd need to get access to some AVCHD and MPEG-2 libraries that would let you combine together multiple files without re-rendering."
This can be done in Vegas for those formats that smart render. I do a lot of 720 60P projects in V12, and smart rendering for MPEG actually works (unlike V10). Here's what I do which is a real time saver. Once a render is completed, I add it as a new track. For any changes, I set up a loop region around the change and render (usually Cineform) it to a new video track using Rosebud's "Render to Video Track 1.5" script. The resulting "prerender" track is always on top. Once the corrections are made, I "solo" the top 2 tracks and render.
My current 25 minute project took a little over an hour to render. I discovered a missing fade, changed a couple of stills and re-rendered using the above technique in 9 min--a substantial time savings.
Perhaps someone else will find this useful, although I'm certain its not a new idea and claim no credit.
