Claim 16:
17. A non-transitory computer-readable recording medium storing a bitstream which is generated by a method performed by a video processing apparatus, wherein the method comprises:
determining, for a conversion between a current video block of a video and the 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, generating the bitstream based on the determining,
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.
