I am regularly getting a one-frame glitch, almost always located in the lower half of a frame that shifts everything over to the right 20-50 pixels and is sometimes dark or slightly brighter than the rest of the image. It rarely happens more than once in a rendered clip, and almost always in the fist 5 seconds. Render always 1080p, Photo-Jpeg .mov
Here is a sample image:
Specs: i7-PC 12MB Ram, AE CS5.5, GTS-450 GPU
Rendering to internal SATA drive.
