NDI Input

To receive NDI streams, set the type of a Live input channel to NDI and select an NDI source. This is done Configuration > Video Input: Live Input. The NDI source can also be changed with the NDI control plug-in. The NDI stream can be used as a regular live input.

If at least one NDI input is configured during startup, Viz Engine scans the network for NDI senders. All discovered sources are shown in the drop down menu.

The configured input video system is only used as the initial value. At runtime, Viz Engine dynamically adapts to changes in the resolution and frame rate of the NDI input stream.

NDI senders are generally not synced and run at slightly different frequencies. To compensate for these differences, Viz Engine skips or repeats NDI input frames as necessary to make playback as smooth as possible.

NDI Output

The Viz Engine output registers itself as NDI stream if a valid license is available and configured and the output is enabled in the Viz Configuration File. The name of the NDI sender is VizEngine-N, where N is the instance number.

By default the NDI output of Viz Engine is a fill and key signal. To send fill only, set "NdiOut1.ContainsAlpha = 0" in the configuration file.

NDI in Software I/O Only Mode

To configure Viz Engine using NDI without any video board:

• Uncheck User Defined in Check Video Card.

• Set the Software I/O Mode to NDI.

• Live inputs can then be mapped to NDI sources in Configuration > Video Input: Live Input.
