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)
VIDEO:  [DIVX]  720x432  24bpp  25.000 fps  5310.8 kbps (648.3 kbyte/s)
Clip info:
Software: MEncoder 1.0pre5-3.3.4

Playing Kill Bill 2.avi.
AVI file format detected.
AVI: ODML: Building odml index (2 superindexchunks)
VIDEO:  [DIVX]  720x416  24bpp  25.000 fps  2612.0 kbps (318.8 kbyte/s)
Clip info:
Software: MEncoder 1.0pre5-3.3.4

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,
Nick
