Adding Background Audio for a Movie
Background audio plays for the entire movie, regardless of which slide
is displayed or how long the slide is on the screen. When other audio
elements play, you can lower the volume of the background audio. If
the background audio file is shorter than the movie length, you can
repeat the background audio in a loop until the end of the movie.
To add background audio to a movie, follow these steps:
1.
From the Edit menu, choose
Preferences
(or from the Audio
menu, choose
Background Audio
).
2.
In the Preferences window, click
Background Audio
under the
Project heading in the Category list if it isn't already selected.
