1. A method of video encoding comprising:
partitioning a video picture into a plurality of coding units (CUs), wherein at least one of the plurality of CUs is further partitioned into a plurality of triangular shape prediction units (PUs);
constructing a motion vector merge list for a CU comprising a plurality of triangular shape PUS;
obtaining a plurality of uni-directional motion vector candidates each comprising one motion vector of a corresponding candidate in the motion vector merge list; and
deriving a predictor for each of the plurality of triangular shape PUs based on a uni-directional motion vector candidate of the plurality of uni-directional motion vector candidates,
wherein obtaining the plurality of uni-directional motion vector candidates comprises:
obtaining respective uni-directional motion vector candidates for the PUs from a plurality of motion vector candidates in the motion vector merge list constructed for the CU, while orders thereof are preserved.
