The latest connectivity combined with ultra-low latency makes KONA X ideal for modern virtual production environments.

This workflow diagram illustrates the KONA X, with its ultra-low latency, as a key part of a virtual production workflow.

KONA X and application software that supports ultra-low latency allows users to achieve the lowest latencies possible, which is important for eSports and live production environments, where the synchronization of AR graphics and graphical overlays and split-second reaction times for viewer interactions are required.

The combination of KONA X's built-in hardware downstream keyer and ultra-low latency allows graphics and images up to 4K/UltraHD to be easily overlaid on the input video in real time. 

AJA Desktop products offer unparalleled workflow compatibility with a range of software applications that span production, post, and delivery, and more. Please click here for compatibility information.

The latest AJA Desktop Software advances 4K workflows with KONA X by providing native support for 4K video in Adobe Premiere Pro, Apple Final Cut Pro, and Avid Media Composer plus many other applications. KONA X offers broad video format support, providing a powerful I/O tool for Sports, eSports, Virtual Production, and other cutting-edge workflows.

HDR (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 X HDR workflows can also benefit from AJA's Control Room application and its companion AJA Control Panel, which comes complete with built-in HDR test patterns. 

AJA Control Room provides VPID signaling for SDR/HDR Transfer Characteristics, Colorimetry, and Luminance transfer characteristics over SDI, bringing flexible output options to your workflow. KONA X provides simultaneous HDR output via both SDI and HDMI.

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

AJA Control Room software also provides the KONA X with HDR Auto Playback Detection. Embedded HDR metadata in a recorded .mov file is read and used to automatically set the HDR format on the monitor(s) connected to the KONA X HDMI and/or SDI outputs. Support for file based .mov HDR outputs with metadata from Adobe Premiere Pro/Adobe Media Encoder HDR files is also available. Screening those rendered outputs is a simple and high quality experience with AJA Control Room. Every frame is presented in its full quality, at the timing intended, and with the proper HDR format set correctly and automatically.

AJA Control Room software

• Supports CEA-608 or 608-in-708 via ANC extraction firmware.

Supplied Avid & Adobe Plugins

• All SMPTE-291 (ANC) based captions supported.
• Adobe Premiere Pro supports native 708 if the raw data is available. For instance in the Adobe plug-ins we handle the case where Premiere hands us full 708 data, we just pass it through to the device.
• Avid Media Composer supports active video ANC (line 21) or ANC via ANC extractor/inserter (up to UltraHD/4K).

Developers who wish to use AJA’s world class SDK (Software Development Kit) can choose between two different methods to gain access and start putting their creativity to work with this rich, deep, and powerful set of video technologies. AJA’s SDK is available on Windows, Linux, and macOS, including support for the latest Apple silicon.

For the quickest and easiest way to get up and running with the core AJA SDK, we recommend the AJA Open Source Developer path, which is under the MIT license and hosted via GitLab.

For access to the AJA SDK, including AJA proprietary technologies and world class support, we recommend the AJA Developer Program path. This is accessed via the dedicated AJA SDK Developer page and requires signup and approval.

It is entirely possible for a developer to begin on the AJA Open Source Developer path, and, if necessary, in the future, apply to enroll in the AJA Developer Program path.

AJA OEM Developers can run select code directly on KONA X with its In-Firmware Microcontroller for functionality that might need to exist before the system containing the card fully boots.  Contact AJA SDK support for more information.

AJA Desktop Software is optimized for the latest Apple silicon with native support for AJA macOS drivers, application plug-ins, AJA Control Room, AJA Control Panel, and AJA System Test.

Supports macOS, Windows, and Linux Ubuntu / Rocky. Please see Release Notes for details and version information which can be found in the Downloads, Software tab.

AJA’s technical support is recognized as among the best in the industry and is available to all AJA customers. If you need assistance with any aspect of your KONA installation, configuration, operation or encounter any technical issue, AJA Support will work with you to get up and running.

KONA products are covered by a generous three year warranty. Please see the individual Product’s Manual for additional specifics around warranty conditions for the product itself.
