1. A method of processing video data comprising:
performing a conversion between a video and a bitstream of the video,
wherein the bitstream conforms to an order of a sub-bitstream extraction process that is defined by a rule that specifies (a) the sub-bitstream extraction process excludes an operation that removes all supplemental enhancement information (SEI) network abstraction layer (NAL) units, which satisfy a condition, from an output bitstream or (b) the order of the sub-bitstream extraction process comprises replacing parameter sets with replacement parameter sets prior to removing the SEI NAL units from the output bitstream.
