1. A method for video processing, comprising:
determining that an affine mode is enabled for a first block of a video;
in response to the affine mode being enabled for the first block, determining whether a first ultimate motion vector expression mode related with the affine mode is applied to the first block;
in response to the first ultimate motion vector expression mode related with the affine mode being applied to the first block, determining a first ultimate motion vector expression mode information for the first block, wherein the first ultimate motion vector expression mode information comprises a first distance index and a first direction information, the first distance index indicates an offset of a refined motion information respective to an original motion information of the first block and the first direction information indicates a direction of the offset; and
performing a conversion between the first block and a bitstream of the video using the first ultimate motion vector expression mode information,
wherein a second ultimate motion vector expression mode related with a non-affine mode is applied to a second block coded with the non-affine mode, wherein the second ultimate motion vector expression mode corresponds to a second ultimate motion vector expression mode information, and wherein the second ultimate motion vector expression mode information comprises a second distance index indicating an offset of a refined motion information respective to an original motion information of the second block and a second direction information indicating a direction of the offset.
