Abstract: A method of video processing is provided to include determining, for a conversion between a video block of a video having a 4:2:2 color format and a bitstream of the video, a parameter of a cross-component linear model for the video block according to a rule and performing the conversion based on the determining, wherein a syntax element indicates whether chroma samples of the video are vertically shifted relative to luma samples of the video and wherein the rule specifies that the parameter is determined independent of a value of the syntax element.

Abstract: A method of video processing is provided. The method includes determining, for a conversion between a video comprising a video unit and a bitstream of the video, whether a first coding tool is enabled for the video unit according to a rule. The rule specifies that the first coding tool and a second coding tool are mutually exclusively enabled. The first coding tool or the second coding tool comprises a sign data hiding tool. The method also includes performing the conversion according to the determining.

Abstract: A method of video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, an operation associated with a list of motion candidates based on a condition related to a characteristic of the current block. The list of motion candidates is constructed for a coding technique or based on information from previously processed blocks of the video. The method also includes performing the conversion based on the determining.
