1. A method of processing video data, comprising:
making a determination, for a conversion between a current video unit of a video and a bitstream of the video, whether a first filtering process is enabled for the current video unit based on a color sampling format of the video; and
performing the conversion according to the determination,
wherein the first filtering process is based on a correlation between a luma component and at least one chroma component of the video in a loop filtering process,
wherein luma positions of luma samples of the luma component used in the first filtering process are determined based on the color sampling format.
