alright I had my syntax wrong I was trying something like:

  mencoder zip.avi -o zip2.avi -ovc x264 -x264encopts pass=1 cqp=26 -oac 
copy

to no avail.  On to new error.

[maustin at zaftra ~]$ mencoder zip.avi -o zip2.avi -ovc x264 -x264encopts 
qp_const 
                                  ant=26:pass=1 -oac copy
