==Original Abstract Submitted==

A method for constraining multi-pass decoder-side motion vector refinement (MP-DMVR) is provided. A video coder receives data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. A video coder receives a motion vector that references a block of pixels in a reference picture based on the received data. A video coder refines the motion vector in a plurality of refinement passes by examining pixels in the reference picture that are identified based on the refined motion vector. The refinement of the motion vector is constrained by a refinement range. The video coder encodes or decodes the current block by using the refined motion vector to produce prediction residuals or to reconstruct the current block.
