Hello all, I'm encoding a computer animation which has very subtle moving gradients, the color is nearly grey. I generate mpeg-2 files with low compression from piped .ppm images. During quiet moments in the animation, you see ugly banding artefacts. When there is more motion, I cannot see the banding any more. Are there any low-level settings I can change to increase quality? Right now, this is my command : PleinMuseum final.script | ffmpeg -f imagepipe -img pnm \ -i - -i bounce_0506.wav \ -target "pal-dvd" -aspect 4:3 -acodec mp2 -ab 128 \ -hq -b 8000 -maxrate 8000 -minrate 8000 -dc 10 PM-DV-p1.mpg I'm very interested in any tips to improve quality, but sadly I'm running out of time for the deadline... Thanks, Erwin Driessens www.xs4all.nl/~notnot
