A device may be configured to determine motion compensation interpolation filter. The device may be configured to select a motion compensation interpolation filter based on whether a block is predicted using uni-prediction or bi-prediction and whether a condition based on a subblock width and a subblock height is satisfied. The motion compensation interpolation filter may be defined according to cos-windowed sinc function.
