 Diamond type & size for motion estimation.
+Motion search is an iterative process.
+Using a small diamond does not limit the search to finding only small
+motion vectors.
+It is just somewhat more likely to stop before finding the very best motion
+vector, especially when noise is involved.
+Bigger diamonds allow a wider search for the best motion vector, thus are
+slower but result in better quality.

+Big normal diamonds are better quality than shape-adaptive diamonds.

+Shape-adaptive diamonds are a good tradeoff between speed and quality.
