Pro Convert SDI 4K Plus

 Magewell Pro Convert SDI 4K Plus encoder converts SDI input signals up to 4K Ultra HD into full-bandwidth NDI streams with extremely low latency, enabling users to effortlessly connect SDI-equipped sources to NDI-enabled media networks, devices and applications.

  • Convert one channel of SD/3G/2K/6G-SDI signal with embedded audio to NDI® stream
  • Loop-through one channel of SD/3G/2K/6G-SDI signal with embedded audio
  • 1 x RJ45 + PoE NDI Output.
  • 6G/3G/HD/SD-SDI Supported.
  • Input up to DCI 4K30 10-Bit 4:2:2 Video.

Magewell PN: 64030 US; 64032 EU; 64033 UK;
64034 AU; 64035 KR; 64036 JP

The device is supplied with different options of power adapters.


The plug-and-play Magewell Pro Convert SDI 4K Plus supports video up to 4K at 30 frames per second with embedded audio over a 6Gbps SDI interface. Automatic input format detection and DHCP-based network configuration eliminate the need for manual setup. Users can simply connect the device, and the encoder will convert or encode the source video automatically at its native resolution and frame rate. An SDI loop-through connection allows the input signal to be sent simultaneously to additional displays or equipment without external splitters or routers, enabling sources to be easily used in new IP workflows without disrupting the customer’s existing traditional video infrastructure.

The Magewell Pro Convert SDI 4K Plus offers a wide range of valuable features for live production use. The compact device features a 1/4″-20 thread for use with standard camera-mounting accessories, while preview and program tally lights provide visual indication when the output NDI stream is being used by another application. A PTZ camera can be connected to the converter and controlled via NDI, while power for the unit can be supplied via Power over Ethernet (PoE) or the included power adapter.

Magewell Pro Convert NDI to HDMI 4K

The 4K SDI model is the second offering in the Pro Convert product line. It joins the recently-introduced Pro Convert HDMI 4K Plus, which can convert HDMI inputs up to 4K at 60fps. Additional Pro Convert models, including 1080p60 configurations for users not requiring 4K resolution, are also planned.


Pro Convert SDI Plus

For users wanting greater control of the conversion process and the rich features of the Pro Convert SDI 4K Plus device, an intuitive browser-based interface provides access to status monitoring, advanced settings and FPGA-based video processing. Functions such as up/down/cross-conversion, de-interlacing and image adjustments are performed directly within the hardware, reducing unnecessary network bandwidth and CPU usage to maximize resource availability for other applications in the NDI workflow.

About NDI® –  (Network Device Interface) software is in the hands of millions of customers worldwide and allows multiple video systems to identify and communicate with one another over IP. NDI can encode, transmit and receive many streams of high quality, low latency, frame-accurate video and audio in real time. This benefits any network-connected video device, including cameras, converters, video mixers, graphics systems, capture cards, and many other production devices.
