The Blackmagic Design Ultimatte 12 HD is a high-performance, real-time hardware compositing processor renowned for producing broadcast-quality chroma keying and advanced compositing effects. It is engineered to solve the complex challenge of cleanly extracting a subject from a green or blue screen background and seamlessly integrating them into a virtual or recorded scene with unmatched realism. The processor utilizes sophisticated algorithms for handling fine details like hair, transparency, and motion blur, while its advanced spill suppression accurately removes color contamination from the foreground subject. A key feature is its support for High Definition formats, allowing it to deliver crisp, detailed composites suitable for live television, broadcast graphics, and studio production.

Housed in a compact 1RU rackmount chassis, the Ultimatte 12 HD is built for reliability in 24/7 broadcast environments. It offers a comprehensive array of inputs and outputs for foreground, background, and key signals, along with professional monitoring and control options. The unit can be operated via its front-panel interface or remotely controlled via software, providing flexibility in different production setups. Beyond basic keying, it includes features for layering multiple composites, adding shadows and depth cues, and color matching the foreground to the background for a cohesive final image. As an industry-standard tool, the Ultimatte 12 HD provides broadcasters, live event producers, and virtual studio creators with the confidence to execute flawless, real-time composites that are critical for modern on-air presentation.
