1. A method of processing video data, comprising:
determining, for a conversion between a current block of a current picture of a video and a bitstream of the video, usage of a wraparound clipping operation that is applied to a reference picture for determining a prediction block for the current block based on at least one syntax element;
performing the conversion based on the determining;
wherein the wraparound clipping operation is used to reselect samples in the reference picture in case that samples are outside the reference picture, and
wherein the at least one syntax element includes a first syntax element included in a picture parameter set (PPS), wherein the first syntax element indicates whether the wraparound clipping operation is enabled in a horizontal direction for the current block, and wherein a value of the first syntax element depends on a first size associated with a coding tree block of the current block and a second size associated with a width of the current picture comprising the current block.
