The AVMatrix UC1218 is a compact HDMI to USB 3.1 Gen 1 video capture converter for live streaming, video conferencing, recording and professional AV applications. It converts an HDMI video signal into a UVC-compliant USB signal and can therefore be detected directly by compatible software without any additional driver installation.
The UC1218 supports HDMI input signals up to 1080p60 and outputs the video signal via USB 3.1 Gen 1. Thanks to UVC and UAC support, the converter is suitable for common applications such as OBS, Zoom, Microsoft Teams, YouTube, Twitch and other streaming or conferencing software.
The capture converter operates driver-free according to the UVC standard and requires no external power supply. Power is supplied via USB, making the UC1218 particularly easy to integrate into mobile setups, streaming workstations, training rooms, conference systems or small production environments.
The HDMI 1.4a input automatically detects input signals and supports video formats up to 1080p60. The signal is transmitted via USB 3.1 Gen 1 at an uncompressed data rate of up to 200 MB/s. Video output is UVC-compliant with YUY2, allowing the UC1218 to be used by many applications as a USB camera.
The AVMatrix UC1218 can take audio from the embedded HDMI signal or process it via the additional 3.5 mm stereo line input. Audio output is UAC-compliant via USB. This makes it easy to integrate camera audio, mixer signals or other line sources into streaming and conferencing applications.
