AJA KONA X Video I/O with Streaming DMA


Designed from the ground up to support next-generation AI and AR workflows, KONA X is a 4-lane, PCIe 3.0 video I/O card with two full-size, bidirectional 12G-SDI BNC connections and two full-size HDMI 2.0 connections, one for input and one for output. AJA KONA X lets users achieve as low as sub-frame latencies with Streaming DMA (Direct Memory Access), which enables powerful real time workflows with no perceptible delay on I/O and processing crucial for implementations such as live sports and virtual production.

Supporting 4K/UltraHD, 2K/HD, SD, 10-bit 4:2:2, 4:4:4 and 12-bit color spaces for pristine image quality, KONA X offers the flexibility to ingest and output with 12G-SDI and full-size HDMI 2.0 ports. The bidirectional 12G-SDI ports provide immense flexibility for capture and simultaneous pass-through, and with the appropriate software, multi-channel capture and streaming.

KONA X is driven by AJA's Control Room and Control Panel software, with support for leading content creation applications, such as Adobe Premiere Pro, Apple Final Cut Pro, Avid Media Composer, FilmLight, OBS Studio, vMix, and much more. KONA X is also compatible with AJA's multi-platform Developer SDK.

For HDR workflows, KONA X supports HDR10+, HLG, PQ, and Dolby Vision for rich color delivery over SDI and/or HDMI. KONA X has the horsepower for your work today and into the future.
