1. A method of processing video data, comprising:
determining, for a conversion between a current video block of a video and a bitstream of the video, that whether or not a first affine mode is allowed for the current video block and whether or not a second affine mode is allowed for the current video block are based on a same dimension constrain; and
performing, based on the determining, the conversion between the current video block and the bitstream,
wherein the first affine mode and the second affine mode are not allowed in response to either a height of the current video block or a width of the current video block being smaller than or equal to 8, and the bitstream omits an indication for the first affine mode and the second affine mode; and
wherein in a case that indications for the first affine mode and the second affine mode are absent in the bitstream, the bitstream is parsed without the indications for the first affine mode and the second affine mode, and the current video block is generated without using an affine mode.
