1. A method of video processing, comprising:
performing a conversion between a video comprising a video picture and a bitstream of the video according to a rule,
wherein the rule specifies that a first syntax element is included in a sequence parameter set that the video picture refers to,
wherein the first syntax element indicates whether a reference picture resampling is enabled and whether one or more slices of the video picture are allowed to refer to a reference picture in an active entry in a reference picture list, and
wherein the reference picture has one or more of multiple parameters that are different than that of the video picture, the multiple parameters include the following six parameters: 1) a video picture width, 2) a video picture height, 3) a scaling window left offset, 4) a scaling window right offset, 5) a scaling window top offset, and 6) a scaling window bottom offset, which are specified by second syntax elements.
