I am getting insane average and peak bitrates with RC3 when transcoding DV material to DVD-compatible MPEG2. I set the peak with -b 8000, yet in reality it overshoots 20% or more, while the average as reported by mplex is very high, close to the peak. mpeg2enc -v 0 -I 1 -f 8 -b 8000 -F 4 -n n -a 3 -o file.m2v -c -q 5 -4 1 -2 1 -s -D 10 -K kvcd -R 2 -M 2 RC2 gives me much better results - the peak bitrate doesn't overshoot, and the average is fairly low, perhaps half the peak, depending on the file. I will try again with a higher -q, but RC3 seems to behave very different from older versions, while RC2 is more similar to the old behavior. -- Florin Andrei http://florin.myip.org/ ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
