The method further includes determining a corresponding motion vector difference for each of the multiple control points of the base predictor based on the determined motion vector for each respective control point. The method further includes generating prediction information of the current block to be included in a coded video bitstream. The prediction information includes (i) a usage flag indicative of the affine merge mode with offset, (ii) offset parameters defining the determined corresponding motion vector difference for each of the one or more of the control points, and (iii) a zero motion vector difference flag for the multiple control points of the base predictor. The zero motion vector difference flag indicates whether offset parameters for the respective control point are provided in the prediction information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signaling of flag indicating zero motion vector difference for a control point","description":"A method for video encoding includes determining a corresponding motion vector for each of multiple control points of a base predictor.
