An example is disclosed for decoding an inter-predicted video block of a video stream. The method may include determining that a motion vector associated with the inter-predicted video block is encoded as a motion vector difference (MVD) between the motion vector and a reference motion vector; obtaining, from the video stream, an indication of a magnitude range of the MVD among a plurality of predefined magnitude ranges for motion vector differences; determining a pixel resolution for the MVD according to the magnitude range; identifying additional MVD information in the video stream based on the pixel resolution; extracting the additional MVD information from the video stream; and decoding the inter-predicted video block based on the pixel resolution, the additional MVD information, the reference motion vector, and a reference frame associated with the motion vector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive resolution for motion vector difference","description":"This disclosure relates to encoding and decoding of motion vector difference for inter-predicting a video block.
