Zusammenfassung:	A method and apparatus for video coding using MMVD (Merge with MVD) mode are disclosed. According to the method, two or more base merge MVs from a merge list are determined for the current block. A modified expanded merge candidate is determined for at least one of two or more base merge MVs using a modified set of search locations if said at least one of said two or more base merge MVs is close to another base MV of said two or more base merge MVs, where at least one search location is different between the nominal set of search locations and the modified set of search locations where the nominal set of search locations comprises one or more defined directions at a set of nominal distances around a target base merge MV. The current block is encoded or decoded using motion information comprising the modified expanded merge candidate.
