Claim 2:
3. A non-transitory computer-readable storage medium storing a bitstream generated by a method, the method comprising:
constructing an affine motion vector predictor (mvp) candidate list for a current block;
deriving control point motion vectors (CPMVs) for control points (CPs) of the current block based on the affine mvp candidate list;
deriving prediction samples for the current block based on the CPMVs;
encoding prediction related information for the current block; and
generating the bitstream including the prediction related information,
wherein based on a constructed affine mvp candidate being available, the affine mvp candidate list includes the constructed affine mvp candidate,
wherein the constructed affine mvp candidate includes candidate motion vectors for a first CP, a second CP and a third CP of the current block,
wherein based on the candidate motion vectors for the first CP, the second CP and the third CP being available, the constructed affine mvp candidate is available, and
wherein based on at least one of a candidate motion vector for the first CP, a candidate motion vector for the second CP or a candidate motion vector for the third CP being not available, the constructed affine mvp candidate is not available and the constructed affine mvp candidate is not included in the affine mvp candidate list.
