Zusammenfassung:	A method and apparatus for video coding using MMVD mode. According to this method, two or more base MVs are determined. Whether the base MVs comprise B similar MVs is checked. If the base MVs comprise B similar MVs, a target base MV is determined from the B similar MVs. A set of MVD candidates are determined by adding offsets to the target base MV. Top MVD candidates are selected from the set of MVD candidates reordered according to TM (Template Matching) cost associated with the set of MVD candidates. The top MVD candidates are divided into B modified MVD candidate sets, where each of the B modified MVD candidate sets is associated with one of the B similar MVs. The current block is then encoded or decoded by using motion information comprising the B modified MVD candidate sets.
