US Patent 11677941 Construction method for inter prediction with geometry partition

Devices, systems and methods for digital video coding, which includes using default motion candidates for video coding, are described. An exemplary method for video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, one or more motion candidates for a geometry partition mode using one or more pairwise average candidates that are obtained by averaging a pair of candidates in a motion candidate list for the current block. The geometry partition mode includes partitioning the current block into multiple partitions. The method also includes performing the conversion based on the determining.
