Batch transcoding script

I've never written a script, but I need a batch transcoder script to execute

- mencoder input.vob -ovc x264 -x264encopts pass=2:bitrate=700:nocabac:subq=6:trellis=1 -vf pp=ci,scale=-10:272 -af volnorm=1 -oac mp3lame -lameopts cbr:br=192 -o ouput.mp4
- mencoder input.vob -ovc x264 -x264encopts pass=2:bitrate=700:nocabac:subq=6:trellis=1 -vf pp=ci,scale=-10:272 -af volnorm=1 -oac mp3lame -lameopts cbr:br=192 -o ouput.mp4

for a bunch of files. The .vob can also be an mkv.

OS= lunix, sh/bash/perl/python is all fine.
