    • Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes processing circuitry for video decoding. The processing circuitry decodes prediction information of a current block from a coded video bitstream. The prediction information is indicative of an intra block copy mode. The processing circuitry selects, from a set including three candidate resolutions, a resolution of a block vector difference for the current block. The selecting comprises determining whether or not a first resolution included in the set is used based on a first flag, when the first flag indicates that the first resolution is not used, selecting one of remaining two resolutions included in the set based on a second flag, wherein the first resolution and the remaining two resolutions are three different resolutions, and the remaining two resolutions include 1-integer-pel and 4-integer-pel based on the intra block copy mode. The processing circuitry determines a block vector of the current block according to the selected resolution of the block vector difference and a block vector predictor of the current block. Then, the processing circuitry reconstructs at least one sample of the current block according to the block vector.
