Rendering Issue

[Dale_The_Bold]

I have put together a long scene and I'm having issues rendering it. The clip is 57 seconds long. When I render 10 second clips of it, it turns out okay. But, when I render the whole thing, using final render settings, the image becomes a negative and the top and bottom are swapped (kind of like the old TVs with the "rolling" picture, only locked into a half roll). The preview screen as it renders is okay, as I check it periodically throughout the day. I am rendering uncompressed.

 

Is there a specific setting combination known to render this kind of result?
