This document contains a draft amendment for changes to the Versatile Video Coding (VVC) standard (ITU-T H.266 ISO/IEC 23090-3). This amendment includes the following: 1) the support of an unlimited level for video profiles; 2) some technical corrections and editorial improvements to the 2nd edition text of VVC; and 3) the VVC-specific supports for some supplemental enhancement information (SEI) messages that may be included in VVC bitstreams but are not to be specified in the VVC specification. These SEI messages include two systems-related SEI messages, one for signalling of "green metadata" as to be specified in ISO/IEC 23001-11 and the other for signalling of an alternative video decoding interface for immersive media as to be specified in ISO/IEC 23090-13, and four other SEI messages, namely the shutter interval information SEI message, the neural network post-filter characteristics SEI message SEI message, the neural-network post-processing filter activation SEI message, and the phase indication SEI message, that are to be specified in a new edition of the Versatile Supplemental Enhancement Information messages for coded video bitstreams (VSEI) standard (ITU-T H.274 ISO/IEC 23002-7).
