+Subpixel motion estimation is used for refining motion estimates beyond mere pixel accuracy, improving compression.

+
+SAD is the fastest method, followed by SATD, RD, RD refinement, and the slowest, QPRD.

+6 or higher is strongly recommended: Psy-RD, a very powerful psy optimization that helps retain detail, requires RD.
