The apparatus includes processing circuitry that decodes coding information of a current block (CB) from a coded video bitstream. The coding information indicates that the CB is coded with a subblock-based affine motion model including affine parameters that are based on multiple control point motion vectors (MVs) for the CB. The processing circuitry determines, based on the coding information, whether to select a subblock characteristic for generating a prediction for a sample in an affine subblock of the CB based on a corresponding subblock MV. In response to selecting the subblock characteristic, the processing circuitry determines the subblock characteristic based on at least one of the affine parameters. The subblock characteristic indicates one of: (i) a subblock size used for generating the prediction for the sample and (ii) an interpolation filter type for the affine subblock."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for video coding using a subblock-based affine motion model","description":"Aspects of the disclosure provide methods and an apparatus for video coding.
