Motion vector correction with adaptive motion vector resolution

摘要

An apparatus, system and method are disclosed for digital video coding including modification of motion vectors with adaptive motion vector resolution.An embodiment of a method for video processing includes, for conversion between a current video block and the current video block, the current video block using a coding tool that adaptively selects a resolution of each motion vector associated with the current video block. Determining a final motion vector, and performing conversion between the current video blocks between the bitstream representations based on the final motion vector, wherein the precision of the stored motion vector of the current video block and the final motion vector The precision of is the same.
