The Magewell Pro Convert 12G SDI 4K Plus is the flagship single-channel SDI NDI encoder in the Pro Convert family — and the only model that accepts single-link 12G-SDI sources at full 4096×2160 60fps with loop-through output. Where the SDI 4K Plus handles 6G-SDI at 4K30, the 12G SDI 4K Plus accepts the highest-bandwidth single-link SDI standard — 12G-SDI at full 4K60 — and encodes it as a Full NDI High Bandwidth stream at the same native resolution and frame rate. For broadcast facilities running 12G-SDI camera chains, production switchers or router outputs at 4K60, this is the definitive Pro Convert encoder, delivering single-cable NDI conversion with simultaneous loop-through, tally, PTZ control and PoE power in the same compact form factor as every other device in the Pro Convert family.
Core Functions & Capabilities
- 12G-SDI to Full NDI 4K60 Encoding: Accepts single-link 12G-SDI at up to 4096×2160 (DCI 4K) at 60fps — encoding the full signal as Full NDI High Bandwidth at up to 4096×2160 60fps 4:2:2 8-bit. No other standalone Pro Convert encoder handles 4K60 from a single SDI input at this bandwidth.
- 12G-SDI Loop-Through Output: Dedicated BNC SDI loop-through passes the full 12G-SDI input signal simultaneously with NDI encoding — maintaining the existing 4K60 SDI signal path to a router, monitor or downstream device without interruption or quality loss.
- Full SDI Standards Compatibility: Accepts SD, HD, 3G, 6G and 12G-SDI (ST 259, ST 292, ST 425, ST 2081, ST 2082) with automatic format detection — compatible with every SDI standard from legacy SD to the latest 12G broadcast infrastructure in a single device.
- 16-Channel SDI Audio: Captures all 16 channels of 12G-SDI embedded audio and encodes them as 16-channel NDI-embedded audio — preserving the complete multi-group audio payload of high-end broadcast cameras and production switchers at 4K60.
- FPGA Video Processing: Onboard FPGA handles deinterlacing, up/down scaling, frame rate conversion and aspect ratio adjustment entirely in hardware — enabling precise NDI output configuration independent of the input format with zero CPU overhead.
- Flexible NDI Output Resolution: Encodes at native 4K60 or any custom resolution and frame rate — enabling full-quality 4K60 programme streams alongside reduced-bandwidth HD or preview streams from the same 12G-SDI source simultaneously.
- PTZ Camera Control: Controls PTZ cameras via VISCA, Visca UDP, Visca UDP2RS232, PELCO-P and PELCO-D through the shared Mini-DIN 8 port — enabling complete remote camera control alongside 4K60 NDI encoding from a single PoE connection.
- Programme & Preview Tally: Dedicated programme (red) and preview (green) tally LEDs on the device with tally signals via Mini-DIN 8 for on-camera tally lights — tally light accessory included in the box.
Key Features
- PoE Powered — Even at 4K60: IEEE 802.3af Power over Ethernet powers the device at full 12G-SDI 4K60 operation — a single cable carries both the NDI stream and device power to the installation point. USB 5V/2.1A also supported.
- Camera Mountable: ¼–20 threaded mounting hole enables direct mounting on camera cages, tripod adapters and accessory brackets — ideal for 12G-SDI broadcast cameras, PTZ cameras and ENG cameras in the field and studio.
- NDI 6.2 Support: Updated to NDI SDK 6.2 — fully compatible with current NDI 4K production infrastructure, software discovery and multi-subnet routing for 4K60 NDI streams.
- Browser-Based Web GUI: Full configuration, signal monitoring and PTZ control via any modern browser — no software installation required. Compatible with IE, Edge, Firefox, Chrome, Safari and Opera.
- Control Hub Compatible: Registers with Magewell Control Hub for centralised management, firmware updates and monitoring across multiple Pro Convert devices — essential for broadcast facilities with multiple 12G-SDI conversion points.
- Crestron & Q-SYS Plugins: Official Crestron SIMPL+ and Q-SYS plugins available — enabling full integration into enterprise AV control systems for professional 4K broadcast and installation projects.
- Modator Chassis Module Available: A module version of the same specification is available for the Magewell Modator 2U chassis — enabling high-density multi-channel 12G-SDI 4K60 NDI encoding in a 2U rack footprint for broadcast equipment rooms and OB trucks.
- Rotary DIP Switch: 16-position onboard switch assigns a unique device index from 0 to F — enabling reliable identification and management of multiple units in the same installation.
Ideal For
- Broadcast Studios — 12G-SDI Camera Chain to NDI: Convert 12G-SDI cameras, studio cameras and production switcher outputs to 4K60 NDI at source — loop-through maintains the 12G-SDI router connection, tally keeps camera operators informed and PoE eliminates mains power runs at camera positions.
- OB Trucks & Mobile Production: Bring 12G-SDI sources from OB trucks and mobile units into NDI-based remote production workflows over IP — feeding production software, streaming encoders and monitoring systems without dedicated SDI connectivity at the receive end.
- 4K60 Live Production & IMAG: Convert 12G-SDI 4K60 cameras at fixed venue positions to NDI — feeding production switchers and IMAG systems at full 4K60 over the venue network while loop-through maintains local SDI monitoring.
- Sports Production — 4K60 Cameras: Convert 12G-SDI 4K60 pitch-side and studio cameras to NDI for IP-based production workflows, replay systems and streaming — with loop-through feeding existing SDI infrastructure simultaneously.
- High-End Corporate & Conference Facilities: Convert 12G-SDI 4K60 cameras in flagship auditoriums and broadcast-standard boardrooms to NDI — integrating with NDI production software and recording systems without replacing installed 12G-SDI cabling.
- Medical & Surgical — 4K60 Imaging: Encode 12G-SDI output from 4K60 surgical cameras and high-resolution diagnostic equipment as NDI — loop-through maintains the theatre display while the NDI stream feeds recording, telemedicine and consultation room distribution over the clinical network.
