1. A method of processing video data, comprising:
determining, for a conversion between a video comprising a video picture and a bitstream of the video, a scanning process is applied to the video picture, wherein the video picture is partitioned into one or more tiles, one or more slices, and a plurality of coding tree units CTUs;
determining, in the scanning process, whether a height of a first slice in a video tile comprising the first slice in units of CTUs is derived or is included in the bitstream based on a value of a first syntax element corresponding to the first slice; and
performing the conversion based on the determining,
wherein the first syntax element is included in a picture parameter set in the bitstream in response to a set of conditions being satisfied,
wherein the set of conditions comprises that the first slice is in a rectangular mode, a value of a syntax element specifying a difference between a width of the first slice in units of tile columns and 1 is equal to 0, and a value of a syntax element specifying a difference between a height of the first slice in units of tile rows and 1 is equal to 0, and
wherein the height of the first slice is derived for the video in response to the value of the first syntax element being a first value.
