Abstract: Chroma deblocking harmonization for video coding are described. In an exemplary aspect, a method for video processing includes deriving, for a conversion between a video processing unit of the video and a bitstream representation of the video processing unit, at least one decision result associated with decisions in a chroma deblocking filter decision process of the video processing unit; applying a same decision result from the at least one decision result for all chroma components of the video processing unit; and performing the conversion based on the same decision result.

Abstract: A method for processing video data is described and the method includes: deriving, for a conversion between a video processing unit of the video and a bitstream of the video processing unit, at least one deblocking filter associated with a chroma deblocking filter process of the video processing unit; applying a same deblocking filter from the at least one deblocking filter for all chroma components of the video processing unit; and performing the conversion based on the same deblocking filter.

Abstract: History based motion vector prediction is disclosed. In one example method of video processing, initializing, for a conversion between a first region of video and a bitstream of the first region, a first history motion vector predictor (HMVP) table associated with the first region based on at least one of stored multiple HMVP tables, the multiple HMVP tables being used to store motion information associated with regions coded prior the first region; and performing the conversion by using the initialized first HMVP table which includes at least one motion candidate.
