Professional Connectivity

KONA 4 features bi-directional 3G-SDI connections that can be used for input and output. 16-Channels of embedded audio over SDI for multi-channel audio work and HDMI 2.0b monitoring output. LTC I/O, Genlock input, RS-422 control, configurable 3 x BNC SD/HD analog video output and 8-channel AES audio I/O with the K3G-Box all allow KONA 4 to integrate into a variety of workflows from HDR to HFR, 4K to Multi-Channel HD for streaming and more.

Apple silicon Support

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.

HDR

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.

4K Closed Caption Support

AJA Control Room

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

Avid & Adobe Plugins

• All SMPTE-291 (ANC) based captions supported
• Adobe Premiere 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 UHD/4K)

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, and Dolby Vision**), and master to destinations using high quality professional SDI outputs, machine control and analog or tri-level reference. 

*Dolby Vision integration available when using the AJA SDK.

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 4x 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 UltraHD workflows.

4K HDMI output

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

AJA Control Room Metadata Toolset

Metadata is the key for managing advanced workflows. AJA is bringing to market an entirely new way to harvest metadata in the SDI signal stream and export the metadata to a sidecar file.

This new feature, called AJA Control Room Metadata Toolset*, is being introduced in Desktop Software v17.1 and adds the following functionality:

• Supports capture of any metadata type, including SCTE-104 and Dolby Vision metadata, that is part of the SDI Ancillary metadata payload.
• Using an AJA KONA capture card that supports SDI input and the included AJA Control Room software (such as KONA 5 or KONA X), the card captures the metadata, which is then preserved in a metadata sidecar file.
• AJA Control Room can playback the metadata to provide quality monitoring.
• AJA Control Room can export the metadata synchronized with the media on a per-frame basis.

AR support with Unreal Engine

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.

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
