[MPlayer-users] divx file sizes

[Steven Adeff]

I compiled from CVS a few days ago in an attempt to see if the divx encoding 
problems have gotten fixed. I'm still looking into this, but I noticed that 
the encoding quality has gone way down. I used to be able to encode from an 
mpeg1 or 2 file to divx and get about the same quality video but with about 
1/2-2/3 the file size. Now I get a file size that is about the same as 
before, but the video quality is way down. Were there any changes made to the 
commands for 2-pass divx encoding?
here's the commands I'm using(they're in a bash script...)

mencoder $1 -ovc frameno -oac mp3lame -lameopts br=128:vbr=4:q=0 -o 
frameno.avi

then

mencoder $1 -vop pp=ci -ovc lavc -lavcopts 
vcodec=mpeg4:vhq:vbitrate=$bitrate:vpass=1 -oac copy -sws 2 -o output.avi

then

mencoder $1 -vop pp=ci -ovc lavc -lavcopts 
vcodec=mpeg4:vhq:vbitrate=$bitrate:vpass=2 -oac copy -sws 2 -o output.avi


also, does anyone have any hints as to other options to increase the quality? 
I'm not too concerned with the encoding speed as I have an athlon 1800+ doing 
it and its my "second" computer so i just use it for processing power =)

thanks!
