Hello. I've been doing videos in vegas for quite a lot and went through a lot o issues like layer glitching mess, crashes, sound buzzes, etc, and I usually managed to solve them on my own. But this one is a very annoying one, and I've suffered a lot with it. I'm not sure whether it's hardware but I had some tests to define the problem.
Very often moving objects (pan crop) stop at some point in 60fps rendered video.
Take a look (the same video, but rendered in differend fps, snail image has newblue V2 chromakey and sapphire shadow effects on it):
It happened a lot to me with different kinds of images - and I still don't know why it happens.
When i'm looking on preview in vegas it goes fine, but when renders in 60 fps - it stops.
I thought there was a problem with my GPU and removed it - result is the same. Vegas version isn't the cause either - same thing happened on vegas 13 and vegas 14.
I managed to get rid of it once - when tried to render in different formats with different fps, but 1 day later it came back again. What can be the cause of such a glitch? I need help badly.
