1. A method of processing video data, comprising:
determining whether an in-loop reshaping (ILR) is enabled for a conversion between a bitstream of a video comprising one or more video regions and the video;
reconstructing a video unit of a video region by applying information associated with the ILR in a case that the determining determines that the ILR is enabled, the reconstructing of the video unit being based on a bitstream of the video unit in a first domain and a second domain; and
performing the conversion by utilizing fixed clipping parameters unrelated to the information associated with the ILR in a case that the determining determines that the ILR is disabled and utilizing ILR clipping parameters derived according to the information associated with the ILR in a case that the determining determines that the ILR is enabled;
wherein in the case that the determining determines that the ILR is enabled, the ILR clipping parameters represented in the first domain and/or the second domain are used for the conversion.
