Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream. The prediction information is indicative of an affine based motion vector prediction. Further, the processing circuitry identifies consecutive minimum compensation blocks that are adjacent of the current block and affine coded. Then, the processing circuitry determines, based on motion information of at least two minimum compensation blocks in the consecutive minimum compensation blocks, parameters of an affine model, and reconstruct at least a sample of the current block based on the affine model that is used to transform between the current block and a reference block in a reference picture that has been reconstructed.
