Claim 0:
1. A method for processing video, comprising:
deriving, 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 HMVP sub-buffers (HB0, HB1, . . . HBM-1), wherein a second affine HMVP buffer is divided into the M affine HMVP sub-buffers, wherein a first affine HMVP buffer or an 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
performing the conversion by using the affine model.
