1. A method for decoding a video, the method comprising:
obtaining a plurality of sub-blocks by dividing a current block into sub-block units;
deriving motion information of each of the plurality of the sub-blocks by using motion information of co-located sub-blocks corresponding to each of the plurality of the sub-blocks;
generating a sub-block-based temporal merge candidate of the current block by using the derived motion information of the plurality of the sub-blocks; and
generating a sub-block-based merge candidate list of the current block based on the sub-block-based temporal merge candidate, and
wherein when there is a co-located sub-block for which motion information is not available, motion information of a sub-block corresponding to the co-located sub-block for which the motion information is not available is determined as motion information of a center block of the co-located block of the current block,
wherein the co-located sub-blocks and the co-located block are present in a co-located picture of the current block, and
wherein a position of the co-located sub-block and co-located block are determined by a motion vector of a neighboring block of the current block.
