USB 3.0 Capture for Streaming and Recording

The LUOM OZC3-3 connects a 4K@30Hz HDMI source to a PC or Mac over USB 3.0 for live streaming and video capture. It records at up to 1080p 60FPS while passing the original signal through to a display. The device suits creators who need a simple way to bring console or camera footage into OBS and similar software.

Low Power Operation with Passive Cooling

The capture card draws power directly from the USB 3.0 port and requires no external adapter. Its passive design runs silently without fans, keeping noise at zero during long sessions. The USB 3.0 interface provides enough bandwidth for 1080p 60FPS YUY2 capture while maintaining low latency on the HDMI loop-out.

Compact Aluminium Build with Mic Input

A small aluminium enclosure handles heat dissipation and fits easily on a desk or in a bag. One HDMI input and one HDMI output allow pass-through to a monitor without extra splitters. A 3.5mm microphone jack lets you add live commentary, though party chat audio is not captured. The USB-C style connector works with USB 3.0 ports on modern computers.

Questions about this item

How do I install the LUOM OZC3-3 capture card and what step is often missed?

Connect the HDMI source to the input, the display to the HDMI output, then plug the USB 3.0 or USB-C cable into the computer; the step often missed is selecting the device as the video and audio source inside OBS or the streaming software.

What maintenance or replacement will the LUOM OZC3-3 need later?

No routine maintenance is required; if the 3.5 mm microphone jack or the USB cable becomes worn, replacing the cable or using a different headset restores full function.

What limit appears first during a long recording session with the LUOM OZC3-3?

The USB 3.0 output caps captured video at 1080p 60 fps even though the HDMI loop-out can pass 4K at 30 Hz, so sustained capture resolution is the first bottleneck.
