[Continued on next page] = (54) Title: METHOD AND APPARATUS OF VIDEO CODING WITH AFFINE MOTION COMPENSATION (57) : A method and apparatus for video encoding and decoding with affme motion compensation are dis- closed. An embodiment of the method receives input data associated with a current block coded or to be coded in an affme mode. Two or more motion vectors of a neighboring 632 634 block are retrieved from a buffer, where at least one of the 635 retrieved motion vectors is not corresponding to a sub- 63 637 block in a first neighboring block row or a first neighboring block column. The method derives an affme candidate in- 625 cluding affme motion vectors using the retrieved two or 636 more motion vectors, and encodes or decodes the current 626 block by predicting the current block using one or more 612 motion compensated blocks by the derived affine candidate. The buffer for affme candidate derivation stores selective motion vectors less than all motion vectors of coded blocks in the current picture. 616 I) 615 Fig. 6 11111111111111011101111111111101011111011101111111111111011111111110111111111110111111 622 624 633 623 62 W O 20 17157 / 259 Al 61 613 614 60 WO 2017/157259 Al MIDEDIMOM0101011101010MOHOMOVEHOMOVOIMIE Published: — with international search report (Art. 21(3))
