Dynamic range is the span of color and brightness levels that a system can reproduce. Traditionally, Standard Dynamic Range (SDR) supports 8-bits per color channel, for a total of 16.2 million colors. This standard has been sufficient for a long time, but post-processing techniques and the improvements in display and image capture technology have highlighted the limitations of SDR and created a demand for higher quality rendering beyond 8-bits per channel.

High Dynamic Range is the answer to these challenges, with the ability to represent brighter values and get more color accuracy that is not possible with only 8-bits per channel.

HDR-ENABLED PROJECTS NOW HAVE AN EXPOSURE PROPERTY FOR BETTER BLENDING BETWEEN HDR AND SDR LAYERS

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.

NEW PROPERTY FOR HDR VIDEO OUTPUTS IN THE CONFIGURATION EDITOR

Our render engine can now calculate colors with 16-bit floating point precision which enables Ventuz to output an HDR output signal to HDR capable display devices.

The new ‘HDR Color Space’ drop-down lets you manually select the color space for an output device. Color space options for sRGB, Rec.709 (linear), and Rec.2100 (PQ) are supported. The ‘Autodetect’ setting will convert the internal sRGB/Rec.709 colors and linear gamma curve to the detected output color space.

• Adjust the HDR output settings for Video Outputs using the new property drop-down in the Configuration Editor.

• GPU, SDI, CDI, Stream Out, Render to Disk, and VIO output types have all been updated to now support high dynamic range. Images or Videos can now be rendered in HDR compatible formats.

• High dynamic range paired with the new PBR workflow makes graphics rendered by Ventuz look better than ever when paired with an HDR capable display connected to GPU or SDI outputs.
