How can I stop this?!
 

Hi all

Hope somebody can help me to solve this problem. please see the jpeg attachment.

The project is a simple "3D Shuffle" transition with the clouds background on the lower video track, the upper track is two jpegs but I've used pan/crop to make them smaller than full screen and it's causing this masking problem.

Any advice much appreciated..

it's because Vegas sees and moves a full frame of video over a full frame of video so one covers the other, and even though the one frame is "transparent" it's actually covering the other one.

Unless you're comfortable with 3D Track motion, I don't think you're going to find a way around it, but I don't think that it's necessarily an error so much as it's just the way it is when you're moving a full frame over a full frame.

Thanks Dave

That's what I suspected, I could do it with track motion but it would be too time consuming. I'll just have to use the transitions that work...
