I disagree with Quest on this one, and always have. I know it's not for animation, but if it WERE : Your final animation is only as good as it's input source files. If you're doing web animation, no AA might be okay. But if you're doing film like I have been, you'd never, EVER get away without anti-aliasing. Compression doesn't make up for AA mistakes. And did you see one single pixel in the Matrix, or on Gollum in the LOTR? Nope, not one. Do you think for one second that compression is what made those movies so clean?
