1. A video decoding method, the method comprising:
obtaining a first resolution of a to-be-decoded block in a to-be-decoded video frame and a second resolution of a reference block referenced by the to-be-decoded block in a decoded video frame;
when the first resolution is different from the second resolution,
adjusting the first resolution of the to-be-decoded block to a target resolution for block resolution matching, and
adjusting the second resolution of the reference block to the target resolution for the block resolution matching, the target resolution being different from the first resolution and the second resolution and being used to perform the block resolution matching for motion vector determination;
determining, by processing circuitry, a motion vector (MV) of the to-be-decoded block in the first resolution relative to the reference block in the second resolution according to the block resolution matching between the adjusted to-be-decoded block with the target resolution and the adjusted reference block with the target resolution; and
reconstructing the to-be-decoded block in the first resolution based on the MV determined according to the target resolution.
