DeckLink - Live video shows through some transitions
Sometimes when using the DeckLink plug-in and certain transitions, the user will see the live video show up in or behind the transition.
This is caused when the user selects a transparent transition. By design these show what is behind the transition.
Select a different transition.
Turn off or mute the live video feed.
Outside of the DeckLink plug-in use the user could select Fixed Background for the transition however this feature is not supported with DeckLink.
