Still fade-in jumpiness

When I fade in a still photo, the first few dim frames show the picture shifted down about 2-4 pixels. When previewed or rendered, it looks like the photo slides up into place slightly during the fade. Is that a bug or a result of the fading algorithm? I am able to fix it with a pan adjustment. Just wondering if it's only me.

Never happened to me. Using 8.0c.

Is it just that photo or is it any one? I've never seen this happen. However, i've seen the illusion of it if you have horizontal bands of different brightnesses across the image. As the image gets brighter, darker bands will become as bright as lighter bands uses to be and your eye will interpret that as that part of the image moving instead of getting brighter.

Long shot, i know, but i had to ask.

I've never seen this. Short or long fades.
Can't repo.
This sounds like a keyframe jump. Check to see if all pan/crop or track motion keyframes are accounted for.

If you loop the video at the first transition, you can see the jumpiness. Go one frame at a time there.
In the second transition I added pan keyframes to compensate for those first few frames, but wonder why I need to do that. I am using the latest Vegas Video Pro 9.0c.

I've had this problem too. High res png's rendering into a bluray compliant format. Really annoying. I had to blur the still to try and hide it.

It seems to happen at the end of the fade in, just before the image is at final density.
