Abstract
A method of decoding video data includes constructing, by a video decoder implemented in processing circuitry, a candidate list of motion vector information for a portion of a current frame. The method includes receiving, by the video decoder, signaling information indicating starting motion vector information of the candidate list of motion vector information, the starting motion vector information indicating an initial position in a reference frame. The method includes refining, by the video decoder, based on one or more of bilateral matching or template matching, the starting motion vector information to determine refined motion vector information indicating a refined position in the reference frame that is within a search range from the initial position. The method includes generating, by the video decoder, a predictive block based on the refined motion vector information and decoding, by the video decoder, the current frame based on the predictive block.
