1. A method of video decoding performed at a computing system having memory and one or more processors, the method comprising:
receiving video data comprising a plurality of blocks, including a first block and a plurality of residual coefficients for the first block, from a video bitstream;
generating, from the plurality of residual coefficients, a refined residue block for the first block;
generating a reconstructed residue block for the first block, wherein the reconstructed residue block is generated using a short distance intra prediction and the refined residue block; and
reconstructing the first block using the reconstructed residue block and an intra prediction block.
