Pro Convert SDI 4K Plus
6G-SDI 4K to NDI encoder. Similar spec, slightly lower SDI bandwidth.
12G-SDI 4K60 to NDI, SRT and RTMP encoder — the highest-specification SDI encoder in the Pro Convert range for 4K broadcast cameras.
The Magewell Pro Convert 12G SDI 4K Plus is the highest-specification encoder in the Pro Convert SDI range — bringing 12G-SDI 4K60 sources into IP production networks via NDI, SRT and RTMP. It handles the output of the most demanding professional broadcast cameras: Sony VENICE 2, Arri Alexa 35, professional studio cameras and top-specification PTZ systems all use 12G-SDI for 4K output.
By encoding at the camera or source position, the Pro Convert 12G SDI 4K Plus eliminates the need for 12G-SDI infrastructure between the camera and the production system. A single Ethernet cable carries 4K NDI from the encoder to any NDI-capable application on the network — vMix, OBS with NDI plugin, Wirecast, Vizrt, NDI Studio Monitor and any NDI switcher.
The PoE power option means the same Ethernet cable that carries the NDI stream also powers the encoder — a significant advantage in broadcast facilities and remote locations where a separate power circuit at each camera position is impractical.
12G-SDI infrastructure — 12G-rated patch bays, routing switchers and cable runs — is expensive to install and maintain. The Pro Convert 12G SDI 4K Plus provides an alternative: encode 12G-SDI to 4K NDI at the camera, and distribute over standard Ethernet infrastructure already in place in the facility.
This is particularly valuable in broadcast facilities transitioning from SDI to IP infrastructure, in remote production setups where 12G-SDI cable runs would be cost-prohibitive, and in new installations where Ethernet infrastructure is already in place but 12G-SDI routing is not justified.

The Pro Convert 12G SDI 4K Plus is specified for broadcast facilities, film productions and IP infrastructure projects requiring 4K SDI to NDI encoding at the highest specification.
Film and television productions using 12G-SDI cameras (Sony VENICE 2, Arri Alexa 35) can deliver 4K NDI feeds to vMix, Wirecast and production monitoring systems over the existing Ethernet infrastructure — without 12G-SDI routing infrastructure.
Broadcast facilities transitioning from SDI to IP infrastructure can encode existing 12G-SDI camera outputs to 4K NDI at each camera position — delivering 4K video to IP-based production systems before full SDI infrastructure replacement.
Sports venues with 4K SDI cameras can encode each camera to 4K NDI at the camera position, distributing over the venue Ethernet network to production systems, replay servers and streaming encoders without 12G-SDI infrastructure investment.
Premium sports broadcasts using 12G-SDI cameras for 4K coverage can deliver 4K NDI feeds to vMix and Wirecast production systems for simultaneous multi-platform streaming alongside the primary broadcast output.
National broadcasters building 4K IP production infrastructure can use the Pro Convert 12G SDI 4K Plus to bring existing 12G-SDI cameras into NDI workflows, protecting the investment in 4K SDI cameras during the IP transition.
Remote production setups receiving 4K SDI camera feeds can encode to SRT at the camera position for IP contribution back to a central production hub — delivering broadcast-quality 4K over internet connections without satellite infrastructure.
Field production teams covering location stories with 4K SDI cameras can use the Pro Convert 12G SDI 4K Plus to encode and stream 4K via SRT or RTMP to cloud production systems over bonded cellular or location broadband.
Large enterprises with professional 12G-SDI broadcast studios can integrate 4K cameras into NDI-based corporate IP networks — delivering 4K NDI to video conferencing systems, internal streaming platforms and digital signage networks.
Broadcast technology developers, systems integrators and IP infrastructure architects building 4K SDI-to-IP workflows can use the Pro Convert 12G SDI 4K Plus as the encoding component in custom 4K NDI distribution systems.
