Sources creation

NDI is a protocol for transmitting video streams over a TCP/IP network.

Many applications can stream video over the network using NDI, and most PTZ cameras natively support it. Conversion boxes are also available to bridge NDI with HDMI or SDI signals.

Free tools are available on the Newtek website, including NDI integration for VLC, testing utilities, and plugins for the Adobe suite.

If your network does not already provide NDI streams, you can generate test streams with these tools to continue the tutorial.

Adding NDI feeds

For the rest of the tutorial we will assume that 4 NDI streams are currently available on your network.

The Modulo Player server can also stream a Monitoring or an Output in NDI.

In the Media tab, click the button and select NDI Source.

Select the newly created NDI Media and click the button to open the NDI Media Editor.

In the editor, rename the source for easier identification in the project, then choose the desired NDI stream from the Streams list.

If the stream does not appear, click the Refresh button to search for available sources on the network.

Repeat these steps until all 4 NDI sources are added.

Counter

Click the button again and select the Counter media.

Select the newly created Counter and click the icon to open its settings.

Set the Timecode type to Countdown and enter a duration of 2 minutes.

Change the text to TIME LEFT :

Place this media on the SPEAKER screen so it appears as an overlay above the NDI PowerPoint stream, showing the remaining time to the Speaker.
