NOTE: This alert will only display within the vMix Interface and MultiView output.
It is hidden in the Output used by Recording, Streaming etc.

Volume Alert

This volume is based on the Master audio levels.

Fade To Black Alert

Multiple Alerts

When multiple alerts are checked, only one alert will display at a time. As soon as that alert no longer applies, the other alerts will display instead if applicable.
