Abstract
Various techniques and tools for chrominance motion vector rounding are described. For example, during motion compensation, a video encoder or decoder converts luminance motion vectors into chrominance motion vector having quarter-pixel accuracy. Or, during motion compensation, a video encoder or decoder converts luminance motion vectors into chrominance motion vectors using one of multiple available chrominance motion vector rounding modes.
