USB 3.0 4K60Hz capture

The Jansicotek OZC3B is a compact video capturing device that converts an HDMI source to a USB 3.0 signal for computers running Windows 7 or later, Linux or macOS. It targets streamers, educators and professionals who need to record or broadcast gameplay, presentations or camera feeds without installing custom drivers on most systems.

HDMI input with zero-latency loop-out

The single specification that decides suitability is the HDMI input paired with an HDMI loop-out port that introduces no measurable delay. This allows the source signal to pass through to a local display while the capture path sends up to 4K video at 60 FPS or 1080P at 60 FPS to the host software.

Cable and manual included

The bundle supplies a USB 3.0 cable and a user manual so the device works immediately after connection. No additional software discs or adapters are provided, and the hardware relies on standard UAC and UVC protocols for audio at 48 KHz PCM and video in MJPEG or YUY2 formats.

Questions about this item

What does 4K at 60 Hz actually deliver when the card is connected to a PC?

The device captures one HDMI source at up to 4K resolution and 60 frames per second, sending video and audio over USB 3.0 to software such as OBS for streaming or recording.

How does the USB 3.0 interface limit capture performance in practice?

USB 3.0 provides the bandwidth needed for 4K 60 Hz capture; the card also supports 1080p at 60 fps with HDCP and converts audio to 48 KHz PCM for broad software compatibility.

What physical connections are required to fit the capture card into a streaming setup?

One HDMI input from the source, one HDMI loop-out for a monitor with zero latency, and one USB 3.0 port on the host computer using the supplied cable.
