high quality mode, encode each macro block in all modes and choose the best.
.B mbd=<0\-2>
macoblock decision algo (high quality mode), encode each macro block in all modes and choose the best.
This is slow but results in better quality and file size.

Allow 4 motion vectors per macroblock (slightly better quality).
