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 video unit of a video and a bitstream of the video unit, a search range of a decoder side motion vector refinement (DMVR) process based on coding information associated with the video unit; determining a set of motion candidates based on an initial motion candidate and the search range; and performing the conversion based on the set of motion candidates.

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

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 block in a target picture of a video and a bitstream of the video, first motion information of the target block based on a regular merge mode, the first motion information comprising a regular merge list of regular merge candidates for the target block; determining second motion information from the first motion information based on a geometric partitioning-based merge mode and a redundancy check, the second motion information comprising a geometric partitioning-based merge list of geometric partitioning-based merge candidates for the target block; and performing the conversion based on the first motion information and the second motion information. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency and compression ratios.

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 block of a video and a bitstream of the target block, a combined inter and intra prediction (CIIP) mode associated with the target block; constructing a merge candidate list associated with the CIIP mode; performing an adaptive merge list reordering to the merge candidate list associated with the CIIP mode; and performing the conversion based on the reordered merge 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 motion candidates for motion information for the target block; determining a reordering scheme based at least in part on coding information, the reordering scheme indicating whether and/or how at least one motion candidate in the list of motion candidates is to be reordered; generating a target list of motion candidates from the list of motion candidates according to the reordering scheme; and deriving the motion information for the target block from the target list of motion candidates. 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 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, at least one target intra prediction mode for the current video block based on neighboring reconstructed samples of the current video block; determining a prediction or a reconstruction of the current video block based on a combination of the at least one target intra prediction mode and one of an inter coding tool or a candidate coding tool, the candidate coding tool being used for determining a reference block for the current video block with samples in a current picture associated with the current video block; and performing the conversion based on the prediction or the reconstruction of the current video. Compare with conventional solutions, the proposed method can advantageously improve coding efficiency and coding quality.

Abstract: Methods, systems and apparatus for video processing are described. One example video processing method includes performing a conversion between a video including a video region and a bitstream of the video according to a rule, wherein the rule specifies that an adaptive loop filtering operation is allowed for the video region in response to an absence of one or more adaptation parameter set (APS) network abstraction layer (NAL) units that include adaptive loop filtering data.
