Blackmagic Ultimatte 12 - High Performance Chroma Keyer


The Ultimatte 12 chromakey processor from Blackmagic Design performs seamless, real-time processing that enables the keying of action video on chroma keyed backgrounds. In broadcast applications, the ability to use virtual sets is highly appreciated thanks to advanced algorithms and color science that provide the best edge handling, color separation, fidelity and washout suppression. The Ultimatte works in both UltraHD and HD, with sub-pixel processing, to create an enhanced image.

For added versatility, the unit has numerous outputs and connections, and supports a wide range of video standards. Software is easily updated via the USB-C connection, and configuration is managed with the Ultimatte's IP address, which is set via the USB-connected configuration utility. The physical size is a 1RU unit.

The Blackmagic Ultimatte 12 is a broadcast quality chromakeyer that allows real time superimpositions with state-of-the-art graphics. It is ideal for both live and virtual scenarios and includes new algorithms as well as innovative colorimetry. It also offers exceptional edge processing, increased colour separation, outstanding colour fidelity and better removal of excess green or blue. On the other hand, SDI 12G technology makes it easy to work in HD or UHD projects, processing each subpixel individually for unprecedented sharpness.
