1. A method of processing video data, comprising:
determining, for a conversion between a current block of a video and a bitstream of the video, that the current block is split into multiple sub-blocks, wherein each of the multiple sub-blocks is coded in the bitstream using a corresponding coding technique according to a pattern; and
performing the conversion based on the determining;
wherein the pattern specifies that a first sub-block of the multiple sub-blocks is coded using a sub-block-based intra-block copy (sbIBC) coding technique in which reference samples from a video region are used.
