Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target block in a target picture of a video and a bitstream of the video, first motion information of the target block based on a regular merge mode, the first motion information comprising a regular merge list of regular merge candidates for the target block; determining second motion information from the first motion information based on a geometric partitioning-based merge mode and a redundancy check, the second motion information comprising a geometric partitioning-based merge list of geometric partitioning-based merge candidates for the target block; and performing the conversion based on the first motion information and the second motion information. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency and compression ratios.
