For subpixel precision, it supports quarter-pel motion vectors with a 6-tap interpolation filter.
对于亚像素精度，它支持与六抽头插值滤波器四分之一像素运动矢量。

A half pel accuracy and variable block size motion estimation scheme is discussed lastly.
最后讨论了半像素精度和变块大小运动估计方案。

Test results show that the compression strength of pel lets increased by 45. 6% compared to pellets balled with common water under the optimum testing condition - B2C1E1.
