Abstract:
A method for visual media processing, including performing a conversion between a current chroma video block of visual media data and a bitstream representation of the current chroma video block. During the conversion, a chroma residual of the current chroma video block is scaled based on a scaling coefficient. The scaling coefficient is derived at least based on luma samples located in predefined positions.
