The Blackmagic Design Ultimatte 12 HD Mini is a compact, portable hardware keyer that delivers the renowned Ultimatte quality in a streamlined, desktop-friendly unit. It is engineered to perform professional, broadcast-level chroma keying and compositing in real-time, making it ideal for live streaming, small studio productions, and mobile setups where space and portability are concerns. Despite its smaller size, it incorporates the same advanced image processing found in larger Ultimatte models, capable of producing clean keys on challenging green or blue screen footage, handling fine details like hair and semi-transparent objects, and applying accurate spill suppression. Its simplified interface focuses on essential controls, making it accessible while still providing the precision needed for high-quality results.

The unit features HDMI and SDI inputs for both foreground (camera) and background (graphics/video) sources, and outputs a clean composite signal along with a key fill. It supports High Definition resolutions, ensuring compatibility with modern cameras and production standards. The Ultimatte 12 HD Mini can be controlled directly via its physical buttons and on-screen display or connected to a computer for more detailed parameter adjustment using Ultimatte software. By packaging professional compositing power into a small, affordable, and easy-to-use device, it empowers solo creators, educators, corporate video teams, and event streamers to add sophisticated virtual backgrounds and layered graphics to their live productions, significantly enhancing production value without the complexity of a full-sized system.
