Abstract: Embodiments of the present disclosure provide a method for video processing. The method comprises: determining, during a conversion between a current video block of a video and a bitstream of the video, whether to insert a target motion candidate for the current video block into a prediction list for the current video block based on a comparison between the target motion candidate and at least one existing motion candidate in the prediction list; and performing the conversion based on the determination. The proposed method can advantageously fill the prediction list more efficiently.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises determining, during a conversion between a target video block of a video and a bitstream of the video, a prediction of the target video block from a buffer set. The target video block is coded with intra block copy (IBC) mode. The method further comprises performing the conversion based on the prediction. Compared with the conventional solution, the proposed method can advantageously improve the IBC buffer design and thus improve the coding effectiveness and coding efficiency.
