Adjust subpel refinement quality.
This parameter controls quality versus speed tradeoffs involved in the motion
estimation decision process.
subq=5 can compress up to 10% better than subq=1.

Runs fullpixel precision motion estimation on all candidate
macroblock types.
-Then selects the best type.
-Then refines the motion of that type to fast quarterpixel precision (fastest).
+Then selects the best type with SAD metric (faster than subq=1, not recommended
+unless you're looking for ultra-fast encoding).

+Does as 0, then refines the motion of that type to fast quarterpixel precision
+(fast).
.IPs 2
Runs halfpixel precision motion estimation on all candidate macroblock types.
-Then selects the best type.
+Then selects the best type with SATD metric.
Then refines the motion of that type to fast quarterpixel precision.
.IPs 3
As 2, but uses a slower quarterpixel refinement.
.IPs 4
Runs fast quarterpixel precision motion estimation on all candidate
macroblock types.
-Then selects the best type.
+Then selects the best type with SATD metric.
Then finishes the quarterpixel refinement for that type.
.IPs 5
Runs best quality quarterpixel precision motion estimation on all
candidate macroblock types, before selecting the best type.
-Also refines the two motion vectors used in bidirectional macroblocks,
-rather than reusing vectors from the forward and backward searches.

.IPs 6
Enables rate-distortion optimization of macroblock types in
I- and P-frames (default).
