Thanks for the response, Dave. I did some reading myself and am a bit clearer on the "Delta" scheme for flics (only the changing pixels get updated). I understand why dithered flics are so big. But as an even more basic question, Why are large, solid areas of color (for instance a solid rendering background) dithered in patchy areas and with different patterns for different frames of a dithered flic. To demonstrate, try rendering a simple animation over a solid background with dither on. Once rendered, you'll notice that in odd angular areas, the solid color is dithered and "creeps" from frame to frame, even though there is no real motion in the solid color. I can't explain it. Anyone have info regarding? Jim Spoto
