x264: disable subq=0 (the huge bitrate penalty wasn't worth the speed), 

and set default subq to best. wording.
renumber direct_pred (temporal seems to be best)

Spatial and temporal are approximately the same speed, and neither is
strictly better than the other.
The best choice depends on the movie.
Spatial and temporal are approximately the same speed and PSNR,
but temporal often looks better.
direct_pred=0 is usually both slower and lower quality.

Adjust subpel refinement quality.
This parameter controls quality versus speed tradeoffs involved in the motion
estimation decision process.
It can improve quality significantly.
