Magewell Pro Convert SDI 4K Plus

NDI to 4K SDI Converter: Send NDI Video to Broadcast SDI Infrastructure at 4K

The Magewell Pro Convert SDI 4K Plus is a standalone NDI receiver that converts NDI video streams into a 4K SDI output over 12G-SDI. At £742, it is the device that bridges NDI production networks with high-end broadcast SDI infrastructure operating at 4K resolution. If your NDI workflow needs to feed a 4K broadcast chain, SDI router, or monitor that accepts 12G-SDI, this is the converter that handles that integration reliably.

What 12G-SDI Means

Standard HD-SDI carries signal at up to 1.5Gbps. 3G-SDI reaches 3Gbps for 1080p50/60 and high-frame-rate HD formats. 12G-SDI carries up to 12Gbps, enabling 4K60 video over a single BNC cable. It is the 4K extension of the SDI standard used in high-end broadcast facilities, premium sports production, and 4K outside broadcast. If your infrastructure includes 12G-SDI routers, monitors, or production switchers and you need to feed them from an NDI production network, this converter handles that bridge without any host PC or additional software.

What It Does

The Pro Convert SDI 4K Plus connects to your Ethernet network as a standalone appliance, receives an NDI stream from any NDI source on the network, decodes it, and outputs a 12G-SDI signal at 4K. Configuration is handled through a web browser management interface. No host PC is required. The device supports the full NDI ecosystem, receiving streams from vMix, Wirecast, NewTek TriCaster, other Magewell Pro Convert TX devices, and any other NDI-capable source.

Who Needs This

• Broadcast facilities with 4K SDI infrastructure, including 12G-SDI routers, monitors, and production switchers, who need to receive NDI sources from production software or hardware
• Sports production facilities running NDI-based production but outputting to 4K SDI broadcast chains for transmission or delivery
• Outside broadcast companies with 4K SDI trucks and equipment needing to integrate NDI sources from remote production workflows
• Post-production facilities where NDI sources must be fed into 4K SDI ingest, monitoring infrastructure, or recording systems
• Rental and staging companies providing production solutions where 4K SDI and NDI coexist in the same workflow

Key Technical Capabilities

• NDI input over Gigabit Ethernet
• 12G-SDI output at 4K resolution
• Standalone appliance with web-based management
• No host PC required
• Compatible with all standard NDI sources

Choosing Between the SDI Receiver Options

The SDI receiver range covers three options. The compact Pro Convert for NDI to SDI at £332 outputs HD-SDI in a smaller form at the lowest cost, suitable for HD broadcast SDI environments where physical size or budget efficiency matters. The SDI Plus at £434 outputs HD-SDI in the larger Plus form factor with enhanced management features for permanent rack installations. This device, the SDI 4K Plus at £742, outputs 12G-SDI at 4K for broadcast infrastructure operating at 4K resolution. Choose based on your SDI infrastructure resolution capability. If your monitors, routers, and downstream equipment accept 12G-SDI at 4K, this device is the right specification. For HD SDI infrastructure, either the SDI Plus or the compact NDI to SDI will serve at a lower cost.
