border artifact on render

I am getting an artifact on the final render of my animation. Has anyone else had this problem?

blender 2.49b ubuntu 10.04 64

rgba hd avijpeg are the main render settings

Any help is appreciated.


is that a world background or black object? Is there an uncounted for object in the outliner ? Looks like something is there

That is a world background and not a black object. I did render it as rgba and wondered if that was part of the problem. Doing a re-render at the moment.

I solved this issue by rendering the border 1 or 2 pixels wider than the standard. It is just a work around and doesn’t address the central issue of the artifact source.
