I was thinking about your prob this weekend. I remembered on the yahoo groups list that some editor from espn was complaining about the field render errors that Carrara was creating in the rendering process. When I first rendered my car commercial last year there was a lot of flutter b/c I used Carraras field render. I think that the field render sucks in Carrara & Raydream from what I read. I am pretty sure the best way to do what you want is to render it into an uncompressed pict sequence (.pict, .tiff, .psd) and then use aftereffects to output it in the correct size/resolution/dpi etc that premiere requires. There are 2 many factors that the carrara/raydream engine doesnt take into account..pal/ntsc, square/non-square, etc.
