The Magewell USB Fusion connects two HDMI sources (slides, cameras, documents) and a USB webcam and combines them into a single, polished composite output that appears as one USB capture device on your computer. Multiple layout options — side-by-side, picture-in-picture, full-screen — let you switch presentation style on the fly.
Used extensively in universities, corporate training rooms, and broadcast facilities, USB Fusion simplifies multi-source productions that would otherwise require complex switching hardware or software. Plug it in, configure the layout, and your presenter appears alongside slides or documents in a single, professional-quality stream.
All compositing is done in hardware by USB Fusion's onboard processor. No software needed for the compositing itself — your PC just receives the finished composite via USB, leaving CPU resources free for streaming, recording, or conferencing software.
Combine a camera, slides, and document camera into one polished composite for Zoom, Teams, or Webex lectures.
Professional multi-source presentations for virtual town halls, webinars, and hybrid meetings.
Switch between sources and layouts live during a production, with the composite delivered to OBS or vMix over USB.
Two camera angles and a laptop output composited in hardware — a lightweight solution for small-scale live productions.
