Capture Device and Target User

The LUOM OZC3B is a new HDMI video capturing device built for streamers and content creators who need to bring a console, camera or phone feed into a computer. It accepts an HDMI source up to 4K at 60 Hz and sends the captured signal over a USB 3.0 connection for live broadcasting or recording.

4K Input and 1080p Recording Headroom

The unit handles HDMI input resolutions up to 4K at 60 Hz but records or streams at a maximum of 1080p at 60 fps. It supports MJPEG and YUY2 video formats plus 48 KHz PCM audio, automatically detecting the incoming video and audio format and converting to the set output size and sample rate.

Build Integration and Connectivity

A single USB 3.0 port carries both power and data to Windows 7 through 10, Linux or Mac OS, with some Windows 7 systems requiring a driver install. An HDMI loop-out passes the source signal onward to a display without added latency, while 3.5 mm microphone input and headphone output let you mix live commentary directly on the device.

Questions about this item

Will the HDMI loop-out on the OZC3B let me keep playing on my existing monitor at 4K 60Hz while I capture?

Yes — the HDMI output passes the signal through at up to 4K 60Hz with no added delay, so your monitor shows the same image while the USB 3.0 connection records 1080p 60fps.

How can I confirm the OZC3B is capturing at 1080p 60fps and 48KHz audio after I plug it in?

Open your streaming or recording software, select the device, and verify the video preview shows 60fps and the audio input is set to 48KHz PCM; the card auto-detects and converts both formats.

Does the OZC3B box include the USB 3.0 cable and a 3.5mm mic, or do I need to buy them separately?

The package contains the capture unit with HDMI in/out and USB 3.0 port; a USB 3.0 cable and any 3.5mm microphone or headphones are not included and must be sourced separately.
