1. A method implemented by a video decoder and comprising:
receiving a video bitstream comprising a sequence parameter set (SPS) raw byte sequence payload (RBSP), wherein the SPS RBSP comprises a first SPS level flag, wherein the first SPS level flag equal to a first value specifies that an affine inter flag is present in coding unit syntax, and wherein the affine inter flag equal to the first value specifies that for a current coding unit, when decoding a P slice or a B slice, affine model based motion compensation is used to generate a predicted pixel of the current coding unit; and
decoding a video sequence from the video bitstream according to the first SPS level flag.
