macOS NDI Desktop Source Monitor

NDI Monitor allows monitoring of broadcast NDI Protocol IP Video Sources using a macOS computer. Audio is also monitored, and sources with an alpha channel are keyed against a checkerboard background.

NDI Monitor automatically finds all NDI sources on the local area network and adds them to the source selection popup menu.

There is also a checkbox to use a Low Bandwidth NDI connection to the source and an audio mute setting.

You can change how Tally is returned to the NDI Source using the menu items.

NDI | HX Sources are also supported, and a PTZ control panel automatically pops up when an NDI device advertises PTZ support. SpaceMouse and SpaceNavigator 3D Controllers can be used to control PTZ.

The SRC button allows you to enter a partial text filter to limit the list of sources shown to match the filter. Very useful if you have lots of NDI Sources on your network.

Great Tool

This user-firendly monitoring application is a very welcome addition to my NDI workflow. It offers more functionality than just rendering NDI sources in real time by letting a user get information about the stream, which is perfect for NDI application development or when testing a new piece of NDI-enabled equipment.
