I have a few DVDs that will only rip to Perfect vobs. I'd like to mencode them down to the Excellent avi quality. I've tried the settings here, but the PQ is very poor. I like the DVD Excellent PQ just fine (with xvid).

Does anyone have the mencoder settings to get a vob to an avi with the Excellent PQ?

TIA

I've been playing around and find a great PQ from these settings...

Code:
mencoder <filename.avi> -ovc xvid -oac mp3lame -xvidencopts fixed_quant=3 -o <output.avi>


However it seems like there are dropped frames that make the avi a little less then perfect smooth playback.

Any assistance here is helpfull. Maybe I'm missing a setting or something easy? Also I'm thinking of changing the 'fixed_quant' to 'max_quant'...

I like to use the 3 pass encoding. I created a script called video2divx.sh. Make it executable (chmod a+rwx video2divx.sh). I can't tell the difference between the original and the divx encoded . There are so many settings available in mencoder and many different ways to do it.

#!/bin/sh
clear
echo "Enter filename to encode:"
read vFile
echo "File name is "$vFile
echo "Stripping sound from "$vFile
mencoder $vFile -ovc frameno -o frameno.avi -oac mp3lame -lameopts abr:br=128
echo "Pass 1 of "$vFile
mencoder $vFile -ni -nosound -oac copy -o /dev/null -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=800:vhq:vpass=1:vqmin=1:vqmax=31 -vop scale -zoom -xy 640 -vf pp
echo "Pass 2 of "$vFile
mencoder $vFile -oac copy -o $vFile-divx.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=800:vhq:vpass=2:vqmin=1:vqmax=31 -vop scale -zoom -xy 640 -vf pp
echo "Cleaning up.."
rm frameno.avi
rm divx2pass.log
echo "Finished encoding "$vFile
