I have Esprit  6 and cannot find the texture AA check box. I don't know if Esprit has this.  I am going to try making the fractal simple as I have fiddled around a bit with the materials.  What about making it a displacement material instead - does that change the way the noise is generated??

I am usinig mpg-2 compression designed for authoring at 24p Widescreen for DVD Architect. Single frames in the time line are super sharp on the large screen but when I space through them even on the timeline in VEGAS I can see the change in noise pattern from frame to frame as I press the ==> key - so this means that each frame is rendered that way.  I will try putting to uncompressed AVI when I render from Vegas but I expect the same result given the previous sentence.
I will also try TIFF to see if any of this improves too - my guess is that it is the noise pattern generated by VUE that looks fine on a single frame but creates unintended "movement" when viewing in an animation.  Thanks for you response.
