Using Vegas 8, clean windows install and everything...

Rendered a project that I have rendered in 7 with no problem many times, only to find that with 8 there is distortion, like a wave at the top of the pics, very noticeable. for now I'm going to ditch the photo so I can get on with project, but does anyone know what's wrong with 8 that this is happening? Yes I did use RIF, not that it would have any effect.

I must have missed what RIF means. Is it a photo format?

Sorry about that, I was referring to Reduce Interlace Flicker. I have moved on to another project using different photos integrated with video and things are working fine...I just ditched the pics in the last project and forgot about it. Still can't figure out what was wrong.
