HDR

HDR or High Dynamic Range,  provides the ability to display a wider and richer range of colours, much brighter whites, and much deeper, darker blacks than standard signals allow. This gives your imagery a more ‘dynamic’ look and allows for natural true to life colours to be communicated to
your audience.

KONA 4 provides this support for your 4K/UltraHD/2K and HD HDR pipelines to HDMI compatible displays in software v13 by offering HDR10 support with HDR 10 Infoframe metadata, in accordance with HDMI 2.0a/CTA-861.3 and HLG support on applicable HDMI displays. Desktop Software v13 introduces HLG support over HDMI for the latest versions of Adobe
Premiere CC.

Powerful

KONA 4’s extensive 4K support allows output directly from editing systems to 4K projectors or monitors, including HFR support at 50/60 fps and 4K HDMI output to support the latest UltraHD monitors, allowing editors and clients to view full resolution 4K images as they work.

KONA 4 also supports AJA Raw capture at up to 120 fps via 4 3G-SDI connections. Create beautiful and detailed slow motion with an engaging cinematic feel via AJA Control Room.

High Frame Rate support

KONA 4 has the power to support 4K High Frame Rate (HFR) at 50p and 60p for the most demanding 4K and UHD workflows.

4K HDMI output

The HDMI output is capable of displaying 4K/UHD via HDMI to many of the latest UltraHD monitors, making full-resolution monitoring affordable while stil maintaining pristine image quality.

 


Integration

KONA 4 supports macOS, Windows and Linux, providing incredible 4K
and multi-channel power for a wide range of applications.

Hardware Keying

The built-in hardware downstream keyer allows graphics and images to
be overlaid on the input video to the card for easy overlays. 

Legendary Support

AJA Technical Support is recognized as one of the best in the industry and provided at no additional charge. Our support team will work with you to solve any issues you might encounter and ensure you are up and running as quickly as possible.


 

Extend your Connectivity with K3G-Box

The optional K3G-Box breakout box and cables allow KONA 4 to integrate easily into rack environments, enabling quick access to all video and audio connections without having to get at the back of the tower computer.

Additional K3G-Box functionality over the standard breakout cable comes in the form of eight additional AES audio channels, 2-channel RCA analog audio monitoring jacks, and looping BNC Genlock reference connectors.
