Magewell Pro Convert 12G SDI 4K Plus – 12G-SDI to Full NDI Encoder

Product Overview

The Magewell Pro Convert 12G SDI 4K Plus is a standalone NDI encoder designed to bridge legacy 12G-SDI camera and router infrastructure into IP video workflows, converting one channel of 12G-SDI up to 4Kp60 into a Full NDI stream over standard Gigabit Ethernet. Purpose-built for commercial AV integrators and broadcast engineers who need a reliable 12G-SDI to NDI converter without replacing existing SDI equipment, the unit supports the full SDI signal chain from SD through 12G and includes an active loop-through for parallel distribution. With native Crestron and Q-SYS plugin support, it fits directly into the control systems already managing your conference room, boardroom, or production environment. At $1,099, it delivers professional-grade NDI encoding at a price point accessible to mid-size enterprise AV deployments.

Product Description

The Pro Convert 12G SDI 4K Plus accepts SD, HD, 3G, 6G, and 12G-SDI signals and encodes them as Full NDI High Bandwidth streams at resolutions up to 4096x2160 at 60fps, delivering 4:2:2 8-bit color sampling suitable for professional production and commercial AV distribution. The active SDI loop-through allows the incoming signal to be passed simultaneously to a local SDI display, switcher, or recording device, preserving existing SDI infrastructure while extending the signal into an NDI-based IP video network. Sixteen channels of SDI-embedded audio are carried through the NDI stream, eliminating the need for a separate audio extractor in most installations.

Configuration and monitoring are handled through an intuitive browser-based Web GUI — accessible via any modern browser — or through Magewell's Control Hub platform for centralized management of multiple devices. The unit supports DHCP for zero-touch network assignment and USB RNDIS/ECM for direct PC connectivity during setup. For AV system designers working with Crestron-controlled rooms, Magewell provides a complete SIMPL+ module library; Q-SYS users can deploy the verified Q-SYS Control Plugin available directly from the Q-SYS Asset Manager. PTZ camera control over NDI (VISCA, PELCO-P, PELCO-D) is also supported via the Mini-DIN-8 port, making this unit practical for conference room and training room camera-to-NDI pipelines. Power is supplied via the included 5V adapter or optionally via IEEE 802.3af PoE from a PoE-capable network switch, reducing cable runs in permanent installations. The device carries a compact form factor (117.5 x 66.7 x 23.4 mm) with a ¼-20 threaded mounting hole and an included L-bracket for flexible surface or camera-rig mounting.

Key Features

• 12G-SDI Input with Active Loop-Through — Accepts SD through 12G-SDI (ST 259/292/425/2081/2082) with a simultaneous loop-through output, preserving local SDI distribution while feeding the NDI network.
• 4K 60fps Full NDI Encoding — Encodes Full NDI High Bandwidth streams at up to 4096x2160p60 in 4:2:2 8-bit, compatible with all NDI-enabled software and hardware receivers including vMix, OBS, and NDI Studio Monitor.
• NDI 6.2 Support — Ships with current NDI SDK (v6.2), ensuring compatibility with the latest NDI tools, receivers, and network video infrastructure.
• 16-Channel Embedded Audio — Passes all 16 channels of SDI-embedded audio through the NDI stream without requiring an external audio extractor.
• Crestron and Q-SYS Plugins — Native SIMPL+ modules for Crestron and a verified plugin for Q-SYS provide deep integration into commercial AV control systems for room automation and device monitoring.
• IEEE 802.3af PoE Support — Accepts Power over Ethernet from any 802.3af-compliant switch, eliminating the need for a local power outlet in ceiling or wall installations.
• Browser-Based Web GUI — Full device configuration, signal status monitoring, and firmware updates are accessible via Web GUI from any modern browser on the same network, with no proprietary software required.
• PTZ Camera Control via NDI — Supports VISCA, Visca UDP, PELCO-P, and PELCO-D PTZ protocols over NDI, enabling camera control through NDI-aware production software without a separate serial connection.
• Tally Light Output — Includes a tally light accessory and Mini-DIN-8 breakout for preview/program tally signaling in live production environments.
• HTTP API for Custom Integration — Documented HTTP-based API allows systems integrators to build custom monitoring dashboards, control interfaces, or automation workflows.
• Compact, Mount-Ready Form Factor — The 117.5 x 66.7 x 23.4 mm enclosure includes a ¼-20 threaded hole and L-bracket for camera, wall, or surface mounting in space-constrained installations.

Typical Applications

• Boardroom — converting existing 12G-SDI camera or presentation sources into NDI for IP-based distribution and control
• Conference room — integrating SDI cameras into Microsoft Teams Rooms, Zoom Rooms, or Crestron-controlled meeting environments via NDI
• Broadcast studio — migrating SDI camera feeds into NDI-based production switchers (vMix, OBS, Tricaster) without replacing cameras
• House of worship — bringing PTZ SDI cameras onto an NDI network for live production and streaming workflows
• Government space — feeding 12G-SDI sources into classified or enterprise IP video distribution networks
• Training room — distributing 4K SDI source video to multiple NDI-enabled display endpoints over the LAN

Technical Specifications

Frequently Asked Questions

Q: Does the Pro Convert 12G SDI 4K Plus require proprietary software to configure?
A: No. All configuration is done through a standard browser-based Web GUI accessible on your LAN. Magewell's Control Hub software is optional for multi-device management but is not required for basic operation.

Q: Can this device pass 12G-SDI signals to a local monitor or router while simultaneously encoding to NDI?
A: Yes. The active SDI loop-through output passes the input signal to a local SDI device without interrupting the NDI encoding stream, allowing parallel SDI and IP video distribution.

Q: Is this compatible with Crestron and Q-SYS control systems?
A: Yes. Magewell provides a Crestron SIMPL+ plugin (V1.0.0.0) and a Q-SYS Control Plugin (V1.0.0) for device control and monitoring. Both are available as free downloads from Magewell's website.

Q: What NDI version does this unit support?
A: The current firmware supports NDI 6.2. Magewell issues firmware updates to track NDI SDK releases; updates are applied via the Web GUI with no specialized tools required.

Q: Can I power this device from the network switch instead of a wall outlet?
A: Yes. The unit supports IEEE 802.3af Power over Ethernet. Any 802.3af-compliant PoE switch port can power the device, eliminating the need for a local power outlet at the installation point.

Q: What is Magewell's warranty on this product?
A: Magewell provides a 3-year limited hardware warranty on Pro Convert products. Technical support is available through Magewell's ticketing system and knowledge base.

Q: Is this suitable for 24/7 continuous operation in a commercial installation?
A: Yes. The Pro Convert 12G SDI 4K Plus is designed for continuous commercial AV operation. Operating temperature range is 0–45°C, and no active cooling fan is required in typical installations.
