    Abstract: Techniques for implementing adaptive loop filtering are described. One example method of video processing includes making a first determination, for a conversion between a video unit of a video and a bitstream of the video, a first luma adaptive loop filter, ALF, boundary across which a luma adaptive loop filter is selectively applied to a luma component of the video unit and a second luma ALF boundary; making a second determination, from the second luma ALF boundary, a chroma ALF boundary across which a chroma adaptive loop filter is selectively applied for a chroma component of the video unit; and performing the conversion based on the first determination and the second determination.

    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 current block of a video and a bitstream of the video according to a rule. The rule specifies that selection of a context for coding a syntax element specifying whether the block is split horizontally or vertically is based on a number of allowed vertical splits and a number of allowed horizontal splits. The number of allowed vertical splits includes a number of allowed binary vertical splits and a number of allowed ternary vertical splits, and the number of allowed horizontal splits includes a number of allowed binary horizontal splits and a number of allowed ternary horizontal splits.
