Blackmagic Smart Videohub CleanSwitch 12x12

This compact routing solution is designed for professional broadcast, live production and studio environments where perfectly clean switching is essential. By integrating full frame re‑synchronisers on every input, it allows seamless, glitch‑free transitions between video sources that share the same video standard. This makes it ideal for live workflows where sources cannot always be perfectly timed, while also enabling the unit to function as twelve independent SDI re‑synchronisers for automatic signal retiming. 

The router supports twelve inputs and twelve outputs using advanced 6G‑SDI technology, allowing SD, HD and Ultra HD signals to be connected simultaneously on the same chassis. Automatic multi‑rate detection ensures that each input independently recognises SD‑SDI, HD‑SDI or 6G‑SDI, while clean switching is performed whenever the reference frame rate and video standard match. This flexibility makes the device well suited for modern mixed‑format installations that must handle legacy and UHD signals side by side. 

A precision‑machined metal front panel integrates direct routing buttons, a scroll wheel and a clear 2.2‑inch colour LCD. The display enables visual routing by showing live video sources and routing labels, allowing operators to confidently select signals based on content rather than channel numbers alone. Local configuration and routing can be performed directly from the front panel, while Ethernet connectivity provides full remote control using software panels on macOS and Windows, as well as compatibility with dedicated hardware control panels. 

For system integration, the unit includes tri‑sync or black burst reference input, SDI reclocking on all outputs and RS‑422 router control for external automation systems. Crosspoint settings are preserved during power interruptions and restored instantly, ensuring operational continuity in critical environments. USB connectivity is provided for firmware updates, keeping the router aligned with evolving workflows and standards. 

By combining clean switching, mixed‑format support and intuitive visual routing in a compact form factor, this solution offers exceptional reliability and control for studios, OB vans and live event systems where timing accuracy and signal integrity are paramount.
