摘要：
This paper describes a pre-processing method for HDR video on linear RGB data before converting to a Y'CbCr 4:2:0 representation. The method targets the luminance artifacts that can arise in saturated colors after compression when PQ Y'CbCr 4:2:0 NCL is used. After processing, the resulting Y'CbCr 4:2:0 representation is also more compressible, leading to objective BD rate results of -2.4%. Subjective improvements in compressed material are also clearly visible.
