Abstract: Systems, methods and apparatus for video processing are described. The video processing may include video encoding, video decoding or video transcoding. One example method of video processing includes performing a conversion between a block of a video and a bitstream of the video according to a rule. The conversion is based on an adaptive motion vector difference resolution (AMVR) tool, and the rule specifies that selection of a context for a first bin within a bin string of a first syntax element that specifies the resolution of the motion vector difference associated with an AMVR shift is derived based on usage of a coding mode for the block.

Abstract: A method of video processing is provided to include determining, for a conversion between a video block of a video and a bitstream of the video, a parameter of a cross-component linear model (CCLM) for the video block according to a rule, and performing the conversion based on the determining, and wherein the rule specifies to use a variable representing a neighbouring luma sample in the determining of the parameter of the CCLM only in case that the variable has a certain value.

Abstract: A mechanism for processing video data is disclosed. A conversion is performed between a visual media data including a video unit and a bitstream. The conversion can be performed by a video encoder and/or a video decoder. The video unit is reconstructed, and a guided filter is applied to reconstructed samples in the video unit.

Abstract: Systems, methods, and an apparatus for video processing are described. A video processing method includes determining an application of a partitioning scheme to a video block positioned at a boundary of a video unit based on a rule, and performing a conversion between a visual media data and a bitstream based on the application of the partitioning scheme to the video block.

Abstract: A mechanism for processing video data is disclosed. An Unsymmetric Binary Tree (UBT) partition of a parent block is determined to create two sub-blocks with different dimensions. At least one of the sub-blocks comprises a side that is non-dyadic. A conversion is performed between a visual media data and a bitstream based on the sub-blocks.

Abstract: A mechanism for processing video data is disclosed. An indication is signaled. The indication indicates whether a picture following a dependent random access point (DRAP) picture in decoding order and preceding the DRAP picture in output order is permitted to refer to a reference picture positioned prior to the DRAP picture in decoding order for inter prediction. A conversion is performed between a visual media data and a bitstream based on the indication.
