1. A method for processing video data, the method comprising:
partitioning a coding unit into a plurality of sub-blocks, wherein the coding unit is associated with a first weight;
determining a second weight of a sub-block of the plurality of sub-blocks based on weights of control points, wherein the control points are neighboring corners of the coding unit; and
bi-predicting the sub-block based on the second weight.
