Blackmagic Design Ultimatte 12 HD Mini

Ultimatte 12 Quality Designed for Compact HDMI Workflows

The Ultimatte 12 HD Mini brings the DNA of the Ultimatte 12 series into a 1U chassis in a one-third rack format, ideal when space in the control room is limited or for mobile installations. Designed for HDMI-oriented environments while maintaining 3G-SDI compatibility, it naturally integrates into a Blackmagic ecosystem, delivering consistent output in SD and HD up to 1080p60.

This "mini" approach does not compromise on quality: 10-bit processing, 4:2:2 sampling, and support for Rec 601 and Rec 709 color spaces preserve fine details (hair, transparencies, edges) and maintain believable skin tones during foreground/background blending.

A Compositing Tool for Live Control Rooms, E-Learning, Streaming, and Hybrid Sets

The Blackmagic Ultimatte 12 HD Mini targets content creators, educational studios, service providers, and live control rooms seeking a reliable, repeatable, and quick-to-set-up green screen keying solution. It simplifies the production of web shows, recorded lessons, music streaming, talk shows, or corporate sets with virtual backgrounds, while remaining suited to live broadcast constraints.

The presence of a dedicated monitoring output and cascade monitoring ensures confident decision-making in real conditions: you can check the keying, mattes, and layers without interrupting the program. Additionally, compatibility with Blackmagic Camera Control and tally (with compatible ATEM cameras and switchers) enhances communication between set and control room and speeds up production pace.

Key Features: Matte Precision, Layer Management, and Network Control

10-bit Processing for Clean Edges and Uniform Image

The 10-bit 4:2:2 processing chain aims for stable compositing, with smoother transitions on edges and better preservation of nuances. Rec 601 / Rec 709 support facilitates color alignment between sources and backgrounds for a more realistic result both live and in recording.

Comprehensive Internal Mattes for Precise Subject Isolation

To manage complex areas (shadows, reflections, screen edges, unwanted elements), the device handles internal mattes and dedicated layers: garbage, holdout, layer, and background. This increases precision in subject isolation and reduces spill, especially on wide shots or highly contrasted backgrounds.

Media Library and Control: A Quick-to-Configure Control Room

Ethernet connection up to 1 Gb/s allows fast loading of images and backgrounds into the library, while enabling automation (control via Ultimatte Software Control or network protocol). The 2.2-inch color front panel display speeds up on-site setup, while presets and control via USB-C simplify maintenance and updates.
