Ultimate motion vector expression based pruning for video coding

Abstract:

A video encoder and video decoder are configured to perform an ultimate motion vector expression (UMVE)-based pruning method which is used to prune motion vectors in a motion vector candidate list. The video encoder and video decoder may add one or more motion vector candidates to a candidate list for motion vector prediction for a current block of the video data, determine whether to add a next motion vector candidate to the candidate list based on a UMVE candidate of a respective candidate of the one or more candidates, and encode/decode the current block of the video data using the candidate list.
