Abstract: A method for video processing comprises: determining, during a conversion between a target video block of a video and a bitstream of the video, an intra block copy (IBC)-based mode to be applied for the target video block based on at least one of: a mode based on affine motion compensated prediction, an affine IBC merge mode with block vector differences (MBVD), an intra template matching for IBC mode (TM_IBC), wherein a derived block vector (BV) is used as base candidates for the MBVD, an intra template matching for IBC mode (TM_IBC), wherein a derived BV is used as BV prediction candidate for IBC non-merge mode, an IBC prediction mode based on multi-hypothesis, a mode based on overlapped block motion compensation (OBMC), a mode based on geometric partitioning with the MBVD, or a mode based on geometric partitioning with TM; and performing the conversion based on the IBC-based mode.

Abstract: Embodiments for video processing, including video coding, video decoding and video transcoding are described. One example method includes performing a conversion between a video having one or more layers having one or more video pictures having one or more subpictures and a bitstream of the video according to a rule, wherein the rule defines network abstraction layer (NAL) units to be extracted from a bitstream during a sub-bitstream extraction process to output a sub-bitstream, wherein the rule further specifies that one or more inputs to the sub-bitstream extraction process include a target output layer set (OLS) index (targetOlsIdx) that identifies an OLS index of a target OLS and is equal to an index to a list of OLSs specified by a video parameter set, and wherein the one or more inputs satisfy a set of conditions.

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 current video block of a video and a bitstream of the video, a cost based on at least two error metrics associated with two target blocks of the video, the cost indicting a degree of distortion between the two target blocks; refining coding data of the current video block based on the cost and the two target blocks; and performing the conversion based on the refined coding data. Compare with the conventional solution, the proposed method can advantageously improve the coding quality and the coding efficiency.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing comprises: reordering, during a conversion between a current video block of a video and a bitstream of the video, a plurality of candidate signs of a motion vector difference (MVD) for a motion candidate of the current video block; and performing the conversion based on the reordered plurality of candidate signs. Compared with the conventional solution, the proposed method can advantageously improve coding efficiency and coding quality.
