KONA 4 workflow


Connect your digital sources via 3G-SDI to KONA 4 for capture to a wide variety of formats.

Monitor via HDMI output (HDR10, HLG, Dolby Vision* and HDR10+*), and master to destinations using high quality professional SDI outputs, machine control and analog or tri-level reference. 

*Dolby Vision and HDR10+ integration available when using the AJA SDK.



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 4 HDR workflows can also benefit from AJA's Control Room application and it's 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 KONA 4. HDMI ports that were already HDR compatible will work simultaneously, for 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 4 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 4 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 hi-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.

Apple Mac Pro Compatible

AJA offers full compatibility for the new Apple Mac Pro, including support for AJA Control Room with Metal compatibility as well as extensive support for a range of applications. macOS support for 12.x (Monterey), 11.0 (Big Sur), 10.15 (Catalina), 10.14 (Mojave) is also offered with KONA 4.

For productions handling high resolution workflows all the way up to 4K, KONA 4 is a perfect video and audio I/O companion.


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 4x 3G-SDI connections. Create beautiful and detailed slow motion with an engaging cinematic feel via AJA Control Room.

KONA 4 Operating System Compatibilites

  • macOS support for 12.x (Monterey), 11.0 (Big Sur), 10.15 (Catalina), 10.14 (Mojave).

  • Linux Ubuntu support for 20.04 LTS, 18.04 LTS.

  • Linux Redhat/CentOS (8) and (7) support.

  • Windows 11, 10 and updates.


AR support with Unreal Engine 4.22

Capture real time footage with KONA 4 over SDI 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.
