Abstract:
A method of visual media processing, including: determining, for a current video block, a motion vector for use in a sub-block based motion vector prediction (sbTMVP) process to locate a corresponding block in a collocated picture for a conversion between the current video block and a bitstream representation of the current video block, wherein the motion vector used in the sbTMVP process is computed in accordance with a scaling operation; and performing based on using the motion vector, the conversion between the current video block and the bitstream representation of the visual media data.
