Abstract: High dynamic range (HDR) support is provided for legacy application programs, such as games that are configured to display standard dynamic range (SDR) frames. HDR frames may be generated without modifying the legacy application program. The buffer creation process of the legacy application program is intercepted and modified before creation of the SDR format buffer so that the buffer is configured to use an upgraded SDR format having an increased bit depth compared with a conventional SDR buffer. Rather than tone mapping and quantizing rendered image data to the lower bit depth for storage in the conventional SDR buffer, the rendered image data is tone mapped and quantized for storage at the increased bit depth of the upgraded SDR buffer. Therefore, the luminance and greater dynamic range of the tone mapped data is better preserved compared with outputting conventional SDR frames.

Abstract: A system is provided for generating video content with hue-preservation in virtual production. A processor determines data in a scene-based encoding format based on raw data received in a pre-defined format. The raw data includes a computer-generated background rendered on a rendering panel and a foreground object. Based on the data in the scene-based encoding format, scene linear data is determined. A saturation of the scene linear data is controlled when a first color gamut corresponding to the pre-defined format is mapped to a second color gamut corresponding to a display-based encoding color space. Based on the scene linear data, a standard dynamic range (SDR) video content in the display-based encoding color space is determined. Hue of the SDR video content is preserved, when the rendering panel is in-focus or out-of-focus, based on a scaling factor that is applied to three primary color values that describe the first color gamut.
