Comment 12 for bug 182999

It appears that the mencoder x264 options have changed since I wrote the
patch. The me=3 option has been replaced with me=umh. However, it
appears that using umh over hex has a negligible gain in encoding
quality anyway, so I would recommend deleting the me=3 bit in the
encoding command.

In fact, you can replace the entire option line for the encoding with:

subq=5:8x8dct:frameref=2:bframes=3:b_pyramid:weight_b:threads=auto

for high quality encoding at reasonable speed, and with:

subq=6:partitions=all:8x8dct:me=umh:frameref=5:bframes=3:b_pyramid:weight_b:threads=auto

for ultra high quality encoding at slow speed.

These are the new "recommended" encoding options from the mencoder
homepage
(http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#menc-feat-x264-encoding-options).
