Blackmagic Design Videohub Mini 4x2 12G

The Blackmagic Design Videohub Mini 4x2 12G is an ultra-compact, zero-latency 12G-SDI video router designed for mobile kits, broadcast racks, and DIT (Digital Imaging Technician) carts. Occupying only 1/3 of a rack width, it allows for the simultaneous routing of SD, HD, and Ultra HD video standards up to 2160p60 in a highly portable form factor.

Core Routing Capabilities

• 4 Inputs and 2 Outputs: Features 4 x 12G-SDI inputs, each with a dedicated loop output, and 2 x 12G-SDI main outputs. This allows for signal passthrough to other devices while maintaining full routing flexibility.

• Multi-Rate 12G-SDI: Automatically detects and switches between SD, HD, 3G, 6G, and 12G-SDI rates. This "future-proof" connectivity ensures you can mix legacy 1080i gear with modern 4K 60p equipment on the same router.

• SDI Re-Clocking: All inputs include integrated re-clockers that regenerate the signal to eliminate jitter. This ensures that even after long cable runs, the output signal is clean and free of digital noise.

Advanced Front Panel & Webcam Features

Despite its small size, the 4x2 model includes the same high-end interface features as the larger Mini routers:

• Tactile Cut-Bus Control: The front panel includes dedicated buttons for fast manual switching. To change a connection, simply select the destination and then the source.

• Emergency Front Patching: Includes a front-facing 12G-SDI input and output. Connecting gear to the front input automatically overrides the highest rear input (Input 4), allowing for rapid troubleshooting without reaching behind the rack.

• USB-C Webcam Out: A built-in USB-C port allows the Videohub to appear as a 1080p HD webcam on any computer. This enables you to route any SDI source directly into streaming or conferencing software like Zoom, OBS, or Microsoft Teams.

Performance and Reliability

• Clean Switch Technology: When a reference signal (Black Burst or Tri-Sync) is connected, the outputs can perform "clean switches" between sources of the same video standard, ensuring glitch-free transitions for live monitoring or broadcast feeds.

• Flexible Power: Features an internal 100-240V AC power supply (IEC) and a 12V DC locking barrel input. This dual-power design is ideal for redundant studio setups or battery-powered field operation.

• Remote Management: Can be fully controlled via Ethernet using the Videohub Software Control for Mac, Windows, and iPad, or via hardware panels like the Videohub Master Control Pro.

Technical Specifications

• Video Standards: Supports SD, HD, 2K, Ultra HD, and 4K DCI up to 60 fps.

• Color Precision: 10-bit YUV 4:2:2 or 12-bit RGB 4:4:4.

• Form Factor: 1/3 Rack Unit (1U height).

• Power Usage: Efficient 17W maximum draw.

Operational Insight

The Videohub Mini 4x2 is the ultimate "problem solver" for small-scale productions. It is frequently used to add extra inputs to an ATEM switcher, allowing the operator to pre-select between different playback decks or remote cameras before they ever reach the switcher's main inputs. Because it handles 12G-SDI, it remains a viable piece of kit even as workflows transition fully into high-frame-rate Ultra HD.

Pro Tip

If you are building a "fly-pack" for remote broadcast, the 1/3 rack width allows you to mount three of these units side-by-side in a single rack space using a Blackmagic Teranex Mini Rack Shelf. This gives you a massive 12x6 routing capability in just 1U of space.
