You can enable HDR globally for your Ventuz project to benefit from the highest brightness and darkness tones resulting in the broadest possible contrast. You can also set the SDR white level in nits for your project when enabling HDR color space.
Although Ventuz had already supported HDR for 3D layers, the layer would be processed at 16-bits per color channel and then tone mapped to an 8 or 16 bits SDR color space – and this is still the default behavior when HDR is switched off in the project settings.
HDR Layers in Ventuz are processed internally at 16-bits per color channel and are composited in HDR color space. This allows more precise reproduction of colors and a wider range of brightness and darkness tones, resulting in HDR scenes having the highest possible contrast. Take advantage of this higher contrast by adjusting the new Exposure layer property, for projects with HDR enabled. This gives you finer control for better blending when compositing HDR and SDR layers.
