Dirac uses macroblock structures to introduce a degree of
adaption into motion estimation
by allowing the size of the blocks used to vary. The motion
estimation stage of the encoding is organised by macroblock,
and each combination of block size and prediction mode is tried
using the RDO block-matching metric - this is called mode decision in
the software - and the best solution
adopted macroblock by macroblock.
