1. A method of video processing, comprising:
performing a conversion between a video comprising one or more pictures and a bitstream of the video according to a first rule,
wherein the first rule specifies that a first general constraint information (GCI) syntax element is included at a beginning of a GCI syntax structure in a profile-tier-level syntax structure,
wherein the first GCI syntax element indicates whether one or more GCI syntax elements are included in the GCI syntax structure, and
wherein when the first GCI syntax element equaling zero indicates that the one or more GCI syntax elements are not included in the GCI syntax structure, the GCI syntax structure does not impose a constraint.
