What this capture device does

The LUOM OZC3B captures HDMI video up to 4K@60Hz and records at 1080p 60fps over USB 3.0. It suits streamers, educators and console players who need a simple way to bring gameplay or camera footage into a PC or Mac for live broadcasting or recording.

Build, connectors and daily use

An aluminium alloy body houses one HDMI input and one HDMI loop-out so the source signal passes through to a monitor without added latency. A USB 3.0 port carries video and power to the host, while 3.5 mm microphone input and headphone output handle live commentary and monitoring. The unit supports MJPEG and YUY2 formats and 48 KHz PCM audio with UAC and UVC compliance.

Check your setup before ordering

Verify your computer has a free USB 3.0 Type-A or Type-C port and runs Windows 7, 8, 8.1, 10 or later, Linux or Mac OS. Some Windows 7 installations require a driver download. Ensure your source device outputs HDMI and that you have an HDMI cable for the loop-through connection if you want to keep a local display active. Buyers needing internal PCIe capture or 4K recording should look elsewhere.
