> Hi,
> 
> I recently start using Mencoder to make backups of my DVD's. The command I use to encode a DVD:
> 
> mencoder -dvd-device /mnt/dvd/ dvd://1 -oac copy -vf crop=xxx:xxx:xx:xx -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=9999:vhq:vpass=1 -o ~/movie.avi

> mencoder -dvd-device /mnt/dvd/ dvd://1 -oac copy -vf crop=xxx:xxx:xx:xx -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=9999:vhq:vpass=2 -o ~/movie.avi
> 
> I encoded several movies with these setting, which gave the following result:
> 
> Playing American History X.avi.
> AVI file format detected.
> AVI: ODML: Building odml index (2 superindexchunks)
> VIDEO:  [DIVX]  704x576  24bpp  25.000 fps  4221.6 kbps (515.3 kbyte/s)
> Clip info:
> Software: MEncoder 1.0pre5-3.3.4

> Playing Hero.avi.
> AVI file format detected.
> AVI: ODML: Building odml index (2 superindexchunks)

> Question is:

> Why is there so much difference in the used bitrate?
> Is the bitrate setting over kill? I do care about filesize, 4485 MB is the max since the avi should fit on a dvd5.
> Are there any other settings that I could use in the encoding command?

> Kind Regards,
