Description
The KONA HDMI 4-Channel PCIe capture card provides multi-channel HDMI ingest and high-frame-rate single-stream capture for professional and prosumer video production. It accepts HDMI signals from SD to DCI 4K and can capture two simultaneous 4K/UltraHD 60p streams or four 2K/HD 60p streams. The card is intended for live production, streaming, capture, and multichannel ingest workflows and integrates into common NLE and streaming toolchains.
Key capabilities include four full-size HDMI inputs, one HDMI 2.0 input for high-bandwidth 4K60 capture, and three HDMI 1.4b inputs for HD/2K channels. The device supports up to 8 channels of embedded audio per HDMI input for a combined total of 32 channels across quad-stream operation. It supports 4:2:2 10-bit color depth and HFR capture up to 60p where supported by the input source.
Video performance covers DCI 4K 4096×2160, UHD 3840×2160, 2K, HD, and SD formats across common frame rates including 60, 59.94, 50, 30, 29.97, 25, 24, and 23.98 fps. Single-stream 4K/UltraHD capture supports up to 4:2:2 10-bit and 30/36 bits/pixel RGB or YUV, while quad-stream 2K/HD supports 4:2:2 10-bit at lower per-stream bandwidth. Audio capture supports embedded HDMI audio at 16- and 24-bit, 48 kHz sample rate, synchronous per input.
Connectivity is provided via four Type A HDMI inputs – one HDMI 2.0 and three HDMI 1.4b – and the card occupies an 8-lane PCIe 2.0 expansion slot. The KONA HDMI is compatible with macOS, Windows, and Linux and is supported by AJA software, AJA Control Room for capture, third-party streaming applications like vMix and Telestream Wirecast, the AJA SDK, and V4L2. HDR pass-through from compatible sources is supported over HDMI where available.
The KONA HDMI is suitable for multi-camera live events, streaming rigs, esports capture, recording ingest for post production, and multi-channel monitoring or VJ decks. It handles synchronized embedded audio per input and offers the channel density needed for broadcast ingest racks or compact workstation installations. Developers can integrate capture functions into custom applications using the AJA SDK or V4L2 support on Linux.
Installation is straightforward – install into an available 8-lane PCIe 2.0 slot, attach HDMI sources, install drivers and supporting software, and configure channel routing in your chosen application. The card is built to operate in standard studio environments with specified operating temperature and humidity ranges and ships with driver support for major OS platforms. Its compact profile fits standard workstation slots and provides low-latency capture for real-time workflows.
