Abstract: A method for video processing is proposed. The method comprises: constructing a merge candidate list for a target block of a video in a template matching (TM) merge mode: reordering the merge candidate list for the target block; and performing a conversion between the target block and a bitstream of the video based on the reordered merge candidate list. Compared with the conventional solution, the proposed method can advantageously improve the coding effectiveness and coding efficiency.
