Abstract: The present disclosure provides a solution for video processing. A method for video processing comprises: selecting, for a conversion between a current video block of a video and a bitstream of the video, a target scheme from a plurality of candidate schemes for adjusting a merge candidate for the current video block; and performing the conversion based on the target scheme, wherein the plurality of candidate schemes comprise at least one of a first set of candidate schemes and a second set of candidate schemes, in each of the first set of candidate schemes, a first motion vector (MV) of the merge candidate is adjusted with a first motion vector difference (MVD), and a second MV of the merge candidate is kept unadjusted, in each of the second set of candidate schemes, the second MV is adjusted with a second MVD, and the first MV is kept unadjusted.

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.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: applying, during a conversion between a target block of a video and a bitstream of the target block, a processing procedure to at least one motion candidate in a motion candidate list; reordering the motion candidate list by applying a first reordering process to the motion candidate list after the processing procedure; and performing the conversion based on the reordered motion candidate list.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: constructing, during a conversion between a target block of a video and a bitstream of the video, a list of template matching (TM) merge candidates for the target block in a TM merge mode; reordering a TM merge candidate in the list of TM merge candidates based on a determination whether a first condition is satisfied to perform TM refinement for the TM merge candidate and a second condition is satisfied to perform decoder-side motion vector refinement (DMVR) or multi-pass DMVR for the TM merge candidate; and performing the conversion based on the reordered TM merge candidate. Compared with the conventional solution, the proposed method can advantageously improve the coding effectiveness and coding efficiency.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: applying, during a conversion between a target video block of a video and a bitstream of the video, a multi-hypothesis prediction process for the target video block based on a plurality of motion candidates from a non-regular merge list; and performing the conversion based on a result of the multi-hypothesis prediction process. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency and performance.
