The Vizrt Spark Plus I/O 12G-SDI Converter extends the reach SDI output devices by converting an SDI signal to NDI, allowing a low latency video transmission to travel over ethernet with support up to UHD 4K/60p. For a full NDI run, you’ll need one for encoding and another for decoding and outputting the signal.

Need HDMI Input / Output? We also rent the Vizrt Spark Plus I/O 4K if you prefer to work with HDMI input and output.
If you are experiencing any issue with this device showing up in Newtek Video in encoder mode, we recommend updating to the latest version of NDI tools.
This device can be DC powered using the included AC adapter or powered over ethernet by a compatible network switch (not included).
