Capture specifications

The LUOM OZC4 is a portable HDMI-to-USB 3.0 video capturing device that accepts a 4K input signal at 30 Hz and records or streams at up to 1080p 60fps. An aluminium alloy shell houses a single HDMI input, an HDMI loop-out for zero-latency pass-through, and a 3.5 mm microphone input for live commentary. No driver installation is required on Windows, macOS, Linux or Android.

Who this suits and who it does not

Streamers and educators who need plug-and-play capture from a game console, camera or set-top box at 1080p 60fps will find the device straightforward. Buyers who want to record or stream at 4K 60fps, or who require multiple simultaneous HDMI inputs, should look at a different capture solution.

Build integration

The unit draws power from the USB 3.0 connection and adds an HDMI output that mirrors the source up to 4K 30 Hz, freeing the host computer from driving a second display. A standard AWG 26 HDMI cable up to 15 metres is supported for 1080p sources, and the capture works with common software such as OBS Studio, VLC and Vmix.
