    摘要： The present disclosure refers to a method of video encoding, the method comprising: splitting a current picture (610) of a video into a plurality of coding units, determining a co-located picture (612) for the current picture (610), determining a motion shift vector (630) for a current coding unit (601) according to a motion vector of a spatial neighbor block of the current coding unit (601), wherein the motion shift vector (630) indicates a shift in spatial position between a respective sub-block of a plurality of sub-blocks in the current coding unit (601) in the current picture (610) and a corresponding sub-block in the co-located picture (612) and reconstructing a sub-block-based temporal motion vector for the respective sub-block of the plurality of sub-blocks in the current coding unit (601) from the corresponding sub-block in the co-located picture (612) based on the motion shift vector (630).
