The video is .mov with H.264 compression, if thats what you are looking for.
Inconveniently, I was planning to do slow motion work with the video. Figures 🙁
I did find out the problem, I think, and I fixed it. It appears that the project file got corrupted. So I opened another window of vegas and copy and pasted and now its working with tolerable preview frame rates.
Unfortunately when I try to render the project, which I recently completed, the render process gets nearly nowhere when I get a low memory warning. I clearly don’t have low memory, and I can’t determine what’s wrong.
