Sorry for the shameless plug, but for such a job you may want to have
a look at my tool 'mencgen', which was designed eactly for this kind
of work:

I've added ip_factor and pb_factor to the x264 options file, but I'm
not sure if it's up-to-date for the current version of x264 and mencoder,
any bug report is very welcome. Feel free to ask any questions on the
tool, should you try to use it.
