description The invention discloses a motion vector difference determination method and device, a storage medium and an electronic device, and the method comprises the steps: determining an original matching block corresponding to a current block in a reference frame of a current frame, with the current block being a to-be-coded block in the current frame; offsetting the original matching block along a plurality of preset offset directions in the reference frame to obtain a plurality of derivative matching blocks; under the condition that a first derivative matching block exceeding the reference frame exists in the plurality of derivative matching blocks, offsetting the original matching block along a preset first alternative offset direction in the reference frame to obtain a first alternative derivative matching block, with the first alternative derivative matching block being located in the reference frame, and the first alternative derivative matching block being located in the reference frame; wherein a first deriva
