Claim 2:
3. A non-transitory computer readable medium storing a bitstream, the bitstream including syntax information according to which a computer performs a decoding process of decoding a video from the bitstream using a predicted image, the decoding process comprising:
deriving a maximum number based on a partition shape of a first partition in the video, the maximum number being a first number when the partition shape is a square or a rectangle, and the maximum number being a second number different from the first number when the partition shape is a non-square and a non-rectangle;
generating a motion vector candidate list including a plurality of candidates equal to the derived maximum number, the plurality of candidates being for a first motion vector for the first partition;
decoding an index indicating the first motion vector among the plurality of candidates in the motion vector candidate list from the bitstream based on the maximum number;
selecting the first motion vector from the plurality of candidates in the motion vector candidate list using the index; and
generating the predicted image for the first partition using the first motion vector.
