Whats the resolution of the video you create ?
The mpeg2enc command generates a mpeg-1 movie with a very low bitrate. a mpeg2enc command like that will help: mpeg2enc -f 8 -q 4 -o video.mp2 but generates a MPEG-2 Video file instead. a command like that might produce a better image: mpeg2enc -f 8 -4 1 -2 1 -q 5 -P -N 1.0 -M 2 -E -10 -D 10 -a 2 -o video.mp2 The problem is that MPEG will always soften the image. Because is is a compression where you loose details. You can only make that amount a little bit smaller. If you need that details you need to find a different video codec. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: shadowl...@utanet.at www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------------------------------ Come build with us!
