Abstract: Devices, systems and methods for video processing are described. An exemplary method for video processing includes determining, for a block of a video, a quantization parameter associated with the block, coding the block of the video into a bitstream representation of the video as a palette coded block in part based on a modified value of the quantization parameter, and signaling coded information related to the quantization parameter in the bitstream representation.

Abstract: Chroma deblocking harmonization for video coding are described. In an exemplary aspect, a method for video processing includes determining, for a conversion between of a first colour component of a current block of a video and a bitstream representation of the first colour component of the current block of the video, one or more deblocking parameters associated with the first colour component involved in a deb locking filter process based on one or more quantization parameters (QP) associated with a second colour component of the current block of the video; and performing the conversion based on the determined deblocking parameters.

Abstract: A method of video processing is provided. The method includes determining, due to a dual tree partitioning structure being used for a conversion between a video unit and a coded representation of the video unit, that use of an adaptive color space transformation (ACT) tool is disabled for the video unit; and performing, based on the determining, the conversion by disabling the ACT tool for the video unit, wherein the use of the ACT tool comprises: converting, during encoding a representation of a visual signal from a first color domain to a second color domain, or converting during decoding, a representation of a visual signal from the second color domain to the first color domain.

Abstract: Devices, systems and methods for video processing are described. An exemplary method for video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, that a neighboring block of the current block that is coded in a palette mode is processed as an intra-coded block having a default mode during a construction of a list of most probable modes (MPM) candidates of the current block in case the neighboring block is located above or left of the current block. The method also includes performing the conversion based on the determining.
