Blackmagic Videohub Mini 4x2 12G

This ultra‑small routing solution is designed to expand SDI systems where rack space is limited but reliability and format flexibility are essential. Built in a compact one‑third rack width chassis, it allows multiple SD, HD and Ultra HD video sources to be connected and routed simultaneously with zero latency. By supporting all SDI standards up to 2160p60, it integrates seamlessly into modern production environments while remaining fully compatible with legacy equipment. 

Four 12G‑SDI inputs are provided on the rear panel, each capable of automatically detecting SD‑SDI, HD‑SDI, 6G‑SDI or 12G‑SDI signals. Two dedicated 12G‑SDI outputs deliver clean, stable signals to downstream equipment, with full SDI reclocking on all outputs to maintain signal integrity over longer cable runs. Input re‑synchronisation on all sources enables clean switching, ensuring stable transitions even when sources are not perfectly timed.

The front panel is designed for fast, practical operation in real‑world scenarios. Integrated routing buttons allow quick source selection without the need for external control panels, while a front‑panel 12G‑SDI input provides an emergency patch point for connecting temporary or unexpected equipment. This front connection automatically overrides one of the rear inputs, allowing rapid response without re‑patching the rack. In addition, a USB‑C connection on the front panel offers a webcam‑style video output, making it easy to feed professional SDI sources directly into computers for streaming, conferencing or recording. 

Network connectivity is included via Ethernet, enabling remote configuration and routing using the free Videohub software control panels for macOS and Windows. The unit also integrates smoothly with larger routing systems, preserving crosspoint settings during power interruptions and restoring them instantly on restart. Its small footprint makes it ideal for mobile racks, OB setups and compact studios where flexibility and speed of operation are critical.
