A device for processing high dynamic range and/or wide color gamut (HDR/WCG) video data can be configured to determine a quantization parameter for quantized transform coefficients of a block of the HDR/WCG video data; inverse quantize the quantized transform coefficients based on the determined quantization parameter to determine dequantized transform coefficients; based on the dequantized transform coefficients, determine a block of residual values for the block of the HDR/WCG video data; based on the block of residual values, determine a reconstructed block for the block of the HDR/WCG video data; determine one or more dynamic range adjustment (DRA) parameters for the block of the HDR/WCG video data; adjust the one or more DRA parameters based on the determined quantization parameter to determine one or more adjusted DRA parameters; and perform DRA on the reconstructed block of the HDR/WCG video data using the one or more adjusted DRA parameters.
