Method and apparatus for video coding
Aspects of the disclosure provide methods and apparatuses for video decoding. In a method, a first indicator that indicates an affine motion compensation type when affine motion compensation is used for inter prediction in a video coding sequence is received. The affine motion compensation type is determined to be one of a plurality of affine motion compensation types based on the received first indicator. The plurality of affine motion compensation types includes a 4-parameter affine motion compensation model and a combination of a 4-parameter affine motion compensation model and 6-parameter affine motion compensation model. Furthermore, one of the 4-parameter affine model and the 6-parameter affine motion compensation model is determined to be used to generate prediction samples for a coding unit based on a received second indicator. At least a sample of a current block is reconstructed based on the second indicator.
