View Workflow


HDR or High Dynamic Range,  provides the ability to display a wider and richer range of colors, 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 colors to be communicated to your audience.

KONA HDMI provides support for accepting HDR signals captured over HDMI from gaming stations like the PS4® Pro.

Using KONA HDMI and AJA Control Room software adds support for HDR metadata capture from an incoming HDMI signal. The captured .mov video file will have embedded HDR metadata, allowing the file to be played back at its intended dynamic range.

AR support with Unreal Engine

Capture real time footage with KONA HDMI over HDMI from high quality cameras, meld your footage with your virtual environment created by the Unreal Engine and send it back out in real time to air  - a growing need for broadcasters, augmented reality (AR) needs and more.

Digital film makers also benefit with these new workflows: On set, enhance your live action VFX work with the ability to see a full composite live during the course of the shoot. This results in fewer reshoots, the ability for actors to understand the virtual environment they are working within for stronger performances and ultimately leads to a range of efficiencies and cost savings with the added benefit of a smoother transition into post production.
