Seamless, Zero-Latency 12G-SDI Routing for Professional Broadcasts

Step up to the next generation of professional video routing with the Blackmagic Videohub 20x20 12G. Engineered for the demanding pace of live production, broadcast, and high-end post-production, this advanced video router eliminates latency, providing an instantaneous and reliable connection for all your video sources. Its core strength lies in its incredible flexibility, allowing you to seamlessly connect and route any combination of SD, HD, and Ultra HD video formats simultaneously, without a single compromise on performance.

Designed to be the central hub of your studio, the Videohub 20x20 12G is packed into a compact and robust one-rack unit (1RU) chassis. The elegant front panel is built for speed and confidence, featuring a crystal-clear LCD screen that lets you visually confirm your sources before routing. This 'video-before-routing' capability, combined with crisp routing labels and video standard information, removes guesswork and prevents on-air errors. Take direct control with dedicated buttons for quick selections or use the precision-machined spin knob, which includes an electronic clutch for fluid and intuitive navigation through your sources and destinations.

Beyond its powerful front panel, the Videohub 20x20 12G is a technical powerhouse. It boasts 20 advanced 12G-SDI inputs and 20 12G-SDI outputs, future-proofing your workflow for resolutions up to 2160p60. Each output features automatic SDI re-clocking, which regenerates the video signal to ensure maximum signal quality over long cable runs—a critical feature for maintaining pristine broadcast standards. For integration into larger systems, the router includes Ethernet control, allowing you to manage it remotely using Blackmagic's free Videohub software for Mac and Windows, or even with optional hardware control panels. Whether you're building a new facility or upgrading an existing one, the Videohub 20x20 12G delivers the performance, control, and reliability your professional workflow demands.
