Embodiments of the present disclosure provide a solution for video processing. In a method for video processing, for a conversion between a current video block of a video and a bitstream of the video, a block vector (BV) candidate of the current video block associated with a reference block of the current video block is determined. A validation of the BV candidate is determined based on at least one reconstructed sample and at least one unreconstructed sample of the reference block. The conversion is performed based on the validation. The BV candidate is in at least one of the following coding modes or processes: a combined intra block copy and intra prediction (IBC-CIIP) mode, an IBC with geometry partitioning mode (IBC-GPM) mode, an IBC with local illumination compensation (IBC-LIC) mode, a direct block vector (DBV) mode, or a BV difference (BVD) or BVD sign prediction process.
