did you try to use x264 presets with mencoder as slow , slower, very slow ?

      --preset                Use a preset to select encoding settings [medium]
                                  Overridden by user settings.
                                  - ultrafast,superfast,veryfast,faster,fast
                                  - medium,slow,slower,veryslow,placebo

in such case you shouldn't write subq=1:frameref=3:me=hex:b_adapt:threads=auto:8x8dct

didn't you satisfy with crf=19 ?


also there's another presets in h264enc project
