1. A method of filtering reconstructed video data, the method comprising:
receiving an array of reconstructed luma samples including a P-block and a Q-block that are both adjacent to an intra sub-partitions (ISP) edge;
determining whether a first size of an edge of one of the P-block and the Q-block is greater than or equal to 32, wherein the edge of the one of the P-block and the Q-block is perpendicular to the ISP edge;
determining a first maximum filter length based on the determination of whether the first size is greater than or equal to 32; and
deblocking the array of the reconstructed luma samples based on the determined first maximum filter length.
