1. A method of video decoding performed at a computing system having memory and one or more processors, the method comprising:
receiving a video bitstream comprising encoded video data and one or more syntax elements indicating delta values for a dynamic clipping range for a picture of the encoded video data, wherein the delta values indicate deviations from a 10-bit range of sample values from 64 to 940;
deriving, based on the one or more syntax elements, the dynamic clipping range for the picture of the encoded video data, wherein the dynamic clipping range modifies the 10-bit range of sample values; and
performing one or more clipping operations on the encoded video data using the dynamic clipping range.
