Abstract:

A method for decoding a video according to the present invention may comprise: determining a motion vector precision of a current block, generating a motion vector candidate list of the current block, obtaining a motion vector prediction value of the current block from the motion vector candidate list, determining whether a precision of the motion vector prediction value is identical to a motion vector precision of the current block, scaling the motion vector prediction value according to the motion vector precision of the current block, when the precision of the motion vector prediction value is different from the motion vector precision of the current block, and obtaining a motion vector of the current block using the scaled motion vector prediction value.
