There is no option tu set the bitrate, you get whatever the default would
be. Furthermore, you put very few options to increase the efficiency of the
encoding. I personally use the following settings:

-ovc x264 -x264encopts
frameref=8:bframes=2:8x8dct:me=umh:subq=7:nodct_decimate:trellis=2:weight_b:direct_pred=auto:crf=20

The crf option is the overall quality.
