 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).

 Runs halfpixel precision motion estimation on all candidate macroblock types.

+Then selects the best type with SATD metric.

 Runs best quality quarterpixel precision motion estimation on all
 candidate macroblock types, before selecting the best type.

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