Claim 18:
19. An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
derive, for a conversion between a current block of video and a bitstream of the current block, an affine model for the current block based on affine related information, wherein the affine related information is stored in at least one first affine history motion vector prediction (HMVP) buffer of M first affine HMVP buffers or at least one affine HMVP sub-buffer of M affine sub-buffers (HB0, HB1, . . . HBM-1), wherein a second affine HMVP buffer is divided into the M affine HMVP sub-buffers, wherein the first affine HMVP buffer or affine HMVP sub-buffer is used to store affine related information of blocks coded prior the current block, and wherein M is an integer greater than 1; and
perform the conversion by using the affine model.
