Firefox 153.0 Beta introduces HDR video playback on Windows, PDF merging and editing, a color picker quick action, QR code sharing, and experimental JPEG XL support, along with several privacy and usability enhancements.
This paper presents a method for HDR video generation by leveraging pretrained generative models through logarithmic encoding alignment and camera-mimicking degradation training, enabling effective HDR synthesis without architectural redesign. The approach demonstrates that HDR generation can be achieved simply by adapting existing models to a representation naturally aligned with their learned priors.
