摘要：

We introduce a constant luminance HDR video coding pipeline, which converts the source video to linear Yu'v' color space and applies a dedicated chromaticity transformation before encoding. This reduces perceivable color artifacts without modifying the core codec itself. We validate our approach by a user study that shows a significant improvement in perceived color quality at high compression rates without sacrificing luminance quality compared to current standard coding pipelines.
