Multi-Source Video Selector and Mixer

The BZBGEAR BG-UHM is a compact professional video device that connects up to three sources via USB 3.0, USB 2.0 and HDMI 1.4 inputs. It blends two inputs into a single output using picture-in-picture, side-by-side or overlay layouts configured through a web interface. The unit is designed for live production, streaming and conferencing setups that need flexible source switching and mixing.

Interface Limits and Control Options

HDMI input accepts 1920x1080 at 60Hz and 1280x720 at 60Hz, while USB 3.0 and USB 2.0 inputs are limited to 1920x1080 at 30Hz and 1280x720 at 30Hz. The HDMI 2.0 output delivers up to 3840x2160 at 60Hz, and the USB-C UVC/UAC output provides 1920x1080 at 30Hz. Control is available via LAN, RS-232 or the web GUI, and the device supports PoE 802.3af for simplified power delivery.

Capacity and Headroom for Production Workflows

The mixer handles three simultaneous sources and combines two at once, which suits typical dual-camera or camera-plus-screen configurations. Audio mixing across HDMI, USB and analog jack inputs covers most live broadcast needs. Layout flexibility is constrained to two-source composites, so productions requiring three or more simultaneous layers will need a larger switcher.

Questions about this item

Should I pick the USB 3.0, USB 2.0 or HDMI 1.4 input for my main camera?

Use HDMI 1.4 for 1920x1080 at 60 Hz; USB 3.0 and USB 2.0 both cap at 1920x1080 30 Hz so they suit secondary sources.

What does the 3840x2160 60 Hz HDMI output actually deliver in my setup?

The HDMI 2.0 port can send 3840x2160 at 60 Hz or 30 Hz and also 1920x1080 at 60 Hz, matching most displays and recorders.

Does the LAN or RS-232 control cap the mixing layouts I can use?

LAN, RS-232 and the web GUI all give full access to PiP, side-by-side and overlay layouts without limiting the mixing options.
