Abstract: A video codec that encodes or decodes video sequences using decoder-side motion vector refinement is provided. The video codec identifies a first motion vector and a second motion vector for coding a current block of pixels of a current video frame in the video sequence. The video codec determines whether to perform motion vector refinement for the current block of pixels based on a comparison between a linear dimension of the current block of pixels and a threshold. When motion vector refinement is performed, the video codec refines the first and second motion vectors to minimize a distortion cost and codes the current block of pixels by using the refined first and second motion vectors. When motion vector refinement is not performed, the video codec codes the current block of pixels by using the identified first and second motion vectors.

Abstract: A video decoder determines whether the current block is coded by using intra block copy mode. The video decoder identifies a list of one or more prediction candidates for the current block. When the current block is not coded by using intra block copy mode, one or more spatial neighbors of the current block that are positioned in a same MER as the current block are excluded from the list of prediction candidates. When the current block is coded by using intra block copy mode and the list of prediction candidates belongs to a predefined subset of multiple different candidate lists, at least one of the identified prediction candidates is a spatial neighbor of the current block that is positioned in the MER. The video decoder reconstructs the current block by using a prediction candidate selected from the list of prediction candidates to generate a prediction of the current block.
