NDI

Viz Engine fully supports the NDI protocol. This can be either done by using the native Viz NDI Integration or in combination with Matrox.

NDI only

To configure Viz Engine using NDI only (NDI-Viz):

  • Install a video version of Viz Engine.

  • Make sure any Video Board is disabled.

  • Set the Software I/O Mode to NewTek Tricaster.

  • Enable the number of stream inputs for your output system in the Video Input section.

Once the engine has been configured and started, it discovers all available NDI sources within the network.

Note: Sources created after Viz Engine has started are not available, as discovery currently only happens within the startup procedure.

Sources can be assigned by selecting a source in Configuration > Video Input: Stream Input.

Note: Audio is currently only fully supported on progressive formats.

This NDI stream can be used afterwards as a regular stream input.

Note: If a source can not be discovered, install the NDI tools from Newtek and manually add the source by using the NDI Access Manager.

The output registers itself as NDI stream and the machinename+instance.

Note: The maximum number of inputs is limited by the network capabilities and the resolution. Usually two 1080p inputs on a dedicated network are realistic.

NDI in Combination with Matrox

To use NDI in combination with Matrox video boards input channel type NDI - Matrox can be used in addition to NDI - Viz.

Information: NDI output is disabled by default in combination with Matrox boards to save performance. To enable NDI output, set NdiOut1.Enable = 1 in section MATROX_CONFIG in your Viz Configuration File.
