USB 3.0 Capture for Streaming

The LUOM OZC3B is a USB 3.0 video capturing device that accepts HDMI input up to 4K at 60 Hz and records at 1080p 60fps. It targets streamers and content creators who need a compact dongle for game consoles, cameras or phones. Aluminium alloy construction aids heat dissipation during extended sessions. The device supports MJPEG and YUY2 formats with UAC and UVC compliance.

Check HDMI Source and OS

Verify that your source device provides an HDMI signal no higher than 4K at 60 Hz because the capture limit is 1080p 60fps. Ensure your computer runs Windows 7, 8, 8.1, 10 or later, Linux or Mac OS; Windows 7 may require a driver install. A free USB 3.0 port is mandatory for the advertised low-latency throughput. Confirm your recording software works with UVC devices.

Loop-Out Frees a Display Port

The HDMI loop-out passes the original 4K 60 Hz signal to a monitor or TV without adding latency so you can play while capturing. A 3.5 mm microphone input and headphone output handle live commentary and monitoring in one unit. Automatic detection of input video and audio formats converts sound to 48 KHz PCM without manual setup. The dongle draws power from the USB port so no external adapter is needed.

Questions about this item

What cables and accessories come with the LUOM OZC3B, and what must I provide separately?

The device includes an HDMI input, HDMI loop-out, USB 3.0 port, 3.5 mm microphone input and 3.5 mm audio output. You supply the HDMI source cable, the USB 3.0 cable to the computer and any 3.5 mm microphone or headphones you wish to use.

Should I choose a different version if I only need 1080p capture?

The OZC3B is a single model that accepts HDMI input up to 4K at 60 Hz but records at 1080p 60 fps; no alternative capacity or resolution version is listed.

What does the 4K@60 Hz input figure mean when I am actually recording?

The capture card can receive a 4K 60 Hz signal through its HDMI input and pass it through the loop-out unchanged, while the recorded or streamed video is encoded at 1080p 60 fps.
