AVMatrix UC1218 HDMI to USB-C Uncompressed Video Capture Device

AVMatrix UC1218: Simple, Power-Free HDMI Capture for Any Computer

The AVMatrix UC1218 is an HDMI to USB-C uncompressed video capture device that turns any HDMI source into a plug-and-play webcam on a computer. It is the go-to dongle for bringing cameras, consoles, and laptops into streaming and conferencing software with zero setup. For creators who just want their HDMI camera to show up in OBS, it does exactly one job and does it cleanly.

What UVC Capture Means

The UC1218 follows the UVC and UAC standards (USB Video Class and USB Audio Class) that operating systems support natively, so plugging it in makes the computer see it immediately as a webcam and audio input with no drivers. That is why it works out of the box with OBS, Zoom, Teams, Twitch, and nearly any app on Windows, macOS, and Linux. It captures uncompressed video up to 1080p60 with automatic input detection, and this standard (non-4K) model is optimized for reliable 1080p capture.

Audio Handling and Power-Free Design

The UC1218 captures embedded HDMI audio along with the video and adds a 3.5mm line input for an external audio source, so a mixer or microphone can be blended in. Being bus-powered over USB, it needs no external adapter; a single USB cable carries data and power, which keeps laptop and field setups simple and cable-light.

Where the UC1218 Fits

The UC1218 is built for bringing HDMI cameras and consoles into a laptop, live streaming to OBS, Zoom, or Teams, recording HDMI sources, and webinars and remote production. Streamers, gamers, and remote presenters choose it as a plug-and-play, power-free HDMI capture device; the SDI-input UC1118 covers SDI sources and the UC1218-4K adds 4K60 capture with loop-out.
