The Blackmagic Design Ultimatte 12 4K is a high-end hardware compositing processor engineered for the most demanding live production and virtual studio environments that require ultra-high-definition keying. It builds upon the legendary Ultimatte keying technology, leveraging advanced algorithms to perform flawless, real-time chroma key extraction on 4K video signals. This allows for the seamless integration of live presenters or actors into 4K virtual sets, graphics, or pre-recorded backgrounds with exceptional detail, accurate handling of transparency and motion blur, and sophisticated spill suppression. The processor's ability to work natively with 4K content ensures that composites retain the full resolution and clarity expected in modern broadcast, cinema, and high-end corporate production.

Housed in a robust 1RU rackmount chassis, the Ultimatte 12 4K is designed for continuous, reliable operation in broadcast control rooms and mobile production trucks. It offers extensive connectivity with multiple 12G-SDI and HDMI 2.0 inputs and outputs for foreground, background, and key signals, providing flexibility in system design. Control is available through an intuitive front panel or via Ethernet using dedicated software for detailed parameter adjustment and preset management. Beyond basic keying, it includes features for depth processing, edge blending, and color matching to create convincing, multi-layered composites. As a cornerstone of professional live graphics and virtual production, the Ultimatte 12 4K provides producers and technical directors with the confidence to execute complex, cinematic-quality composites in real-time, pushing the boundaries of what is possible in live visual storytelling.
