Build Out
Build Out is a part of the Motion settings.
The Build Out motion occurs when the shot element is in Live and after the transition will not be. It only occurs when the Smooth transition is active.
Here is what the Build Out controls look like:
To ...
The Popup controls where the motion ends.
For example, if you select "To Left" then the motion will begin wherever the object happens to be and end just off to the left of the visible area of the broadcast.
Fade Out
Controls whether the shot element should fade out.
If Fade Out is unchecked, the element will "pop" out of Live, much like a Cut.
Spin Out
The shot element is spun out of position.
Scale Out
The shot element is scaled out.
Accelerate Out
All of the above actions are done performed in a way that makes them appear to speed up.
