Blackmagic Design Videohub 40x40 12G

40x40 Zero-Latency 12G-SDI Video Router for Broadcast and Live Production

The Blackmagic Design Videohub 40x40 12G is a professional zero-latency video router built for broadcast facilities, live production systems, post-production environments, and AV installations that need flexible high-density SDI signal management. It gives operators a central routing point for connecting cameras, recorders, monitors, switchers, and other SDI equipment without constant cable repatching.

This router features 40 12G-SDI inputs and 40 12G-SDI outputs, with multi-rate 12G-SDI support for SD, HD, Ultra HD, and DCI 4K video up to DCI 4K60. It can route multiple video standards on the same router at the same time, and built-in SDI re-clocking on every 12G-SDI input regenerates the signal for maximum video quality while reducing jitter and signal loss on longer cable runs.

The Videohub 40x40 12G is designed for practical operation in demanding production environments with a built-in control panel, direct entry buttons, a machined metal spin knob, and an LCD that displays live video and routing labels. It also supports Ethernet remote control, Videohub Software Control for Mac, Windows, and iPad, optional Videohub Master Control Pro and Videohub Smart Control Pro panels, and SDK integration for broadcast automation systems.

In real production workflows, the router can be used with multiple HyperDeck recorders for redundant mastering, to route video to multiple streaming processors, or to add extra inputs to an ATEM switcher. Its 2 RU rackmount design makes it well suited for studios, machine rooms, control rooms, and mobile production systems where organized routing and fast access to sources are essential.

System Integration

The Videohub 40x40 12G fits into larger Blackmagic and SDI-based workflows as a central router for cameras, HyperDeck recorders, ATEM switchers, monitors, streaming processors, and other SDI-connected equipment. Ethernet connectivity, software control, optional hardware panels, and SDK support help it integrate into both standalone control positions and larger distributed broadcast systems.

Broadcast Workflow Benefits

For professional users, this type of router reduces cable clutter, simplifies signal changes, and makes it easier to manage complex installations where multiple sources and destinations must be available at all times. Zero-latency routing supports live workflows, while the built-in LCD and direct-entry controls speed up source selection and routing changes during production.

Frequently Asked Questions

What does the Videohub 40x40 12G do?

It routes up to 40 SDI video sources to 40 outputs, allowing users to connect any input to any output or route a single input to multiple outputs from one central router.

What video formats does it support?

It supports SD, HD, Ultra HD, and DCI 4K video formats over multi-rate 12G-SDI connections, including video up to DCI 4K60.

Can it handle different video standards on the same router?

Yes. It can route multiple video standards on the same router at the same time.

How is the router controlled?

It can be controlled from the built-in front panel, through Ethernet remote control, with Videohub Software Control for Mac, Windows, and iPad, or with optional Videohub Master Control Pro and Videohub Smart Control Pro panels.

Why is SDI re-clocking important?

SDI re-clocking regenerates the signal on every 12G-SDI input, helping maintain maximum video quality while reducing jitter and signal loss, especially when longer cable runs are used in larger systems.

Related Equipment and Workflow Compatibility

The Videohub 40x40 12G is commonly deployed with HyperDeck recorders, ATEM switchers, monitors, streaming processors, and other SDI-connected production equipment in Blackmagic Design and general broadcast workflows. Its support for mixed-format routing makes it practical in SD, HD, Ultra HD, and DCI 4K environments.

Because it centralizes routing electronically, it is especially useful in studios and mobile systems where operators need quick access to many sources and outputs without relying on complex patching schemes or external monitoring just to identify signals.

Why Professionals Use This Type of Product

• Centralizes high-density SDI routing in one rackmount system
• Supports live production with zero-latency performance
• Handles mixed-format SD, HD, Ultra HD, and DCI 4K workflows
• Improves signal integrity with SDI re-clocking on every input
• Reduces cable clutter and speeds operational changes

Additional Compatibility Information
