  • 8-lane PCIe 3.0 bandwidth handles demanding 4K workflows
  • 12G-SDI bidirectional ports enable capture and simultaneous pass-through
  • HDMI 2.0 output delivers HDR10 and HLG monitoring
  • 10-bit 4:4:4 and 4:2:2 sampling preserves pristine colour detail
  • HFR support up to 50/60 fps captures smooth high-frame-rate footage

What this card does

The Aja Video Systems KONA-5-R0-S02 is an 8-lane PCIe 3.0 I/O card built for professional video workflows. It handles 10-bit 4K and UltraHD ingest and output at frame rates up to 50/60 fps with 4:4:4 and 4:2:2 color sampling. The card provides bidirectional 12G-SDI ports for capture and simultaneous pass-through plus a full-size HDMI 2.0 output with HFR support. It is suited for facilities working with HDR10 and HLG content.

Interface limits

The card uses an 8-lane PCIe 3.0 connection to move 12G-SDI and HDMI 2.0 signals. That bandwidth caps 4K and UltraHD output at 50/60 fps in 10-bit 4:4:4 or 4:2:2. Higher frame rates or deeper color depths such as 12-bit are not supported over these interfaces. The HDMI 2.0 port is an output only and does not accept an input signal. SDI ports are bidirectional but share the same PCIe throughput ceiling.

Check your setup

Verify that the workstation has a free x8 PCIe 3.0 slot with enough physical length for the card. The product is supplied as the card only and requires a separate PCIe power cable from the power supply. Confirm that your editing or playout application supports the KONA 5 driver set for the intended 10-bit 4K workflow. Ensure monitoring devices accept HDMI 2.0 or 12G-SDI at the required frame rates and color sampling.

Questions about this item

Should I choose the 12G-SDI or the HDMI 2.0 port for 4K 60 fps output?

Both support 4K and UltraHD up to 60 fps; 12G-SDI handles bidirectional ingest and pass-through while HDMI 2.0 is for monitoring with HDR10 and HLG.

What does the 10-bit 4:4:4 spec mean when I am grading HDR footage?

It gives you full 10-bit colour precision in 4:4:4 sampling for pristine 4K HDR10 or HLG monitoring over HDMI 2.0.

How does the PCIe 3.0 x8 interface limit real-world capture bandwidth?

The 8-lane PCIe 3.0 link provides enough throughput for 12G-SDI 4K 60 fps 10-bit 4:4:4 ingest and simultaneous multi-channel workflows.
