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.
