Titler Live's playout interface can open a Message Log panel. This window is where you will find a live breakdown of actions that occur from your project with any of the channel layers.
Navigate to and click the View menu item in the top corner of the playout interface. Select Message Log. This will prompt a new panel named Message Log to open in the playout interface.
This panel logs all actions that occur within the layers of your project. These actions are broken down by when they occurred, what variables were updated, and which actions were triggered.
This log is a great learning tool for understanding how Titler Live behaves as your test or go live with your production.
