The Blackmagic Design Videohub Mini 4x2 12G Router is a compact SDI router with four 12G-SDI inputs, four loop outputs, and two 12G-SDI outputs in a space-saving design just one-third the width of a standard rack. Featuring front-panel controls, Ethernet support, clean switching, and USB-C webcam output, it's a flexible tool for live production, streaming, and on-the-fly signal routing.

Streamlined Cable Management
This router eliminates messy patching by letting you reroute signals through the panel or remotely. It’s ideal for adding inputs to ATEM switchers, HyperDeck recorders, encoders, and monitors—no need to repatch during critical moments. Emergency gear can be connected via the front 12G-SDI ports, giving you fast access without reaching into the rack.

Front Panel Control
Dedicated buttons for input and output selection allow fast switching—simply choose the output and then assign a source. The cut-bus-style layout is designed for small racks, with additional 12G-SDI input/output ports on the front for convenient patching. The USB-C webcam output also enables connection to computers for recording or streaming.

12G-SDI Compatibility
Supports all SD, HD, and Ultra HD formats up to 2160p60. You can connect any SDI device—SD, HD-SDI, 3G, 6G, or 12G-SDI—simultaneously, and the router will manage format switching automatically. 12G-SDI ensures high frame rate Ultra HD through a single BNC cable, while still working seamlessly with standard HD gear.

Clean Switch Outputs
Each video output features clean switch capability for seamless transitions between sources. It’s especially useful when you want to keep a clean feed for a monitor or streaming encoder while using a direct feed for recorders that don’t tolerate added frames. Sources are locked to input one for consistent timing.

SDI Re-Clocking
All 12G-SDI inputs have built-in re-clocking to restore signal quality and reduce jitter. This is vital when running longer cable lengths, as it maintains video integrity and prevents dropouts. It boosts performance even with high-end cables, ensuring cleaner, more reliable feeds across the board.

Emergency Front Panel Patching
Front-facing 12G-SDI connectors give you immediate access to inputs without needing to reach behind the rack. Perfect for quick gear swaps during production or emergency situations. When in use, the front input overrides the highest-numbered rear input.

Webcam Output for Streaming
The front USB-C port appears as a standard webcam to your computer, delivering 1080p HD video from SDI sources. If your source is Ultra HD, it will downscale to HD for full software compatibility. Stream directly into Zoom, Teams, Skype, or pro tools like OBS and XSplit.

Remote and Hardware Integration
Control the router via the Videohub software, connect to a Master Control Pro panel, or integrate it into automated workflows using the free SDK. Assign button functions or build custom automation to suit your setup.

Dual Power Options
Use either the built-in AC power supply with standard IEC cable or connect a 12 VDC source for flexible deployment. Ideal for studio or field use with redundancy for critical applications.
