Adjust the volume of video slides
In Aperture, you can add video clips as individual slides in your slideshow. You work with video
clips in the Slideshow Editor and Browser in the same way that you work with photos. However,
there are additional controls in the Selected Slides pane of the Slideshow Editor for setting the
volume of a video clip. For example, you can mute the audio clip in the main audio track while
the video clip is playing. You can also change the duration of the fade-in and fade-out of the
video clip’s audio to smooth out abrupt transitions between the video clip and the audio clip in
the slideshow’s main audio track.
Note: To trim a video clip or duplicate it so that you can use multiple portions of it in the same
slideshow, see
Work with audio and video in the Viewer on page 168.

Add music and audio to slideshows
Add music and audio to slideshows
You can add music and audio to your slideshow in two ways:
•
Drag a song or an audio clip from the Audio browser to the background of the timeline in the
Browser: Audio added in this way is called the main audio track and is used to play audio, such
as a song, in the background. Clips in the main audio track cannot be edited, but you can add
another audio clip to the end of the track if the slideshow is longer than the audio file. When
an audio clip is added to the main audio track, the background of the timeline in the Browser
turns green.
