Setting a Track’s Default Transition
You can set a default transition for a track. All still clips with their type set to Same as
Track use the transition.
To set a track’s default transition
Click in an empty stream in the Track Editor to show the Track Inspector.
Click the Transition tab.
Choose the transition to use from the Transition pop-up menu.
Choose “not set” if you do not want still clips to use a default transition. (You can still
configure individual clips to use transitions.)
Configure the transition using its specific parameters.
