Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: generating, based on a neighboring block of a current block of a video for a conversion between the current block and a bitstream of the video, a motion candidate list for an intra block copy template matching merge (IBC-TM-MERGE) mode for coding the current block, the neighboring block being coded with a reconstruction-reordered intra block copy (RRIBC) mode; and performing the conversion based on the motion candidate list.
