I probably didn’t word it very well, sorry, basically, when I render a video, Vegas renders 24 frames, or 29 frames, depending on what the framerate is, e.g if I was rendering 60fps, Vegas would render 60 frames, and then pause for 2-3 seconds, then continue to render another set of 24, 29, 60 frames, and so on, hopefully this was easier to understand, and I have never encountered this problem before either, I just upgraded from 10.0 and now I have this problem.
