Video coding method and apparatus, and recording medium storing bitstream

By constructing an intra-frame merge list and utilizing prediction patterns of neighboring and historical blocks, combined with affine prediction of block vectors, the problem of insufficient intra-frame prediction efficiency in high-resolution video compression is solved, thereby improving the compression performance and coding efficiency of the encoder and decoder.
