The AJA KONA 4 is a powerful 4-channel video and audio desktop I/O card with unparalleled features for handling everything from SD to HD, 2K and 4K with full 10-bit 4:2:2 and 4:4:4 sampling for fantastic image clarity and 12-bit support (Application Dependent ). KONA 4 features bi-directional 3G-SDI connections that can be used for input and output as well as 16-Channels of embedded audio over SDI, perfect for multi-channel audio work and HDMI 2.0b monitoring.
Kona 4 has HDR or High Dynamic Range to provide the ability to display a wider and richer range of colors, much brighter whites, and much deeper, darker blacks than standard signals. This gives your imagery a more 'dynamic' look and allows for natural true to life colors to be communicated to your audience. 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.
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 also 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.
