What this capture device does

The LUOM OZC8 is a USB 3.0 and USB-C video capture device that accepts HDMI input up to 4K at 60 Hz and passes the signal through an HDMI loop-out. It is built for streamers, gamers and content creators who want to record or broadcast gameplay from consoles such as PS4 and Switch, or feed from a DSLR or camera, directly into OBS, Twitch or YouTube without installing drivers.

Limits of the USB 3.0 and HDMI interface

The HDMI input supports 4K at 60 fps, yet the loop-out tops out at 4K at 30 fps. Over the USB link the device delivers 1080p at 60 fps or 2K at 30 fps; it falls back to USB 2.0 speeds when a 3.0 port is not available. The 3.5 mm microphone input lets you add live commentary, but the single USB connection carries both video and audio, so bandwidth is shared between them.

Capacity and headroom for everyday use

Capturing 1080p at 60 fps fits comfortably within the USB 3.0 pipeline, giving smooth preview and recording for most streaming setups. Pushing to 4K input is possible for passthrough, yet the capture path maxes out at 2K 30 fps, so high-refresh 4K recording is not supported. Builders who need 4K 60 fps capture or multiple simultaneous inputs should look for a device with higher throughput.

Questions about this item

Should I choose the USB 3.0 or USB-C connection for this LUOM OZC8 capture device?

Both interfaces are built into the same unit; plug the supplied cable into whichever port your computer has and the card will operate at USB 3.0 speeds.

What does the 4K 60 Hz input rating mean when I am actually streaming or recording?

The HDMI input accepts a 4K 60 fps signal from a console or camera, while the USB output delivers up to 1080p 60 fps or 2K 30 fps to your streaming software.

How does the USB 3.0 interface limit capture performance in practice?

USB 3.0 bandwidth caps the recorded stream at 1080p 60 fps or 2K 30 fps even though the HDMI loop-out can pass 4K 60 fps to a monitor.
