Apple DVD Studio Pro 4 - Manual (Page 386)

Using AAC Audio Files from the iTunes Store
DVD Studio Pro is able to import and use AAC format audio files purchased from the
iTunes Store as long as the computer you are using them on is authorized to use them.
If you import iTunes Store files that the computer is not authorized to use, DVD Studio Pro
plays silence when it encounters those files. Additionally, if you select and try to play
an iTunes Store file that the computer is not authorized to play in the Audio tab in the
Palette, DVD Studio Pro plays silence.
Adding Video and Audio Assets
If you created your track by dragging either a video asset or a video/audio asset pair to
the Menu Editor, the Outline tab, or the Graphical tab, it already contains video and audio
clips. If you created your track using the Add Track icon in the toolbar, it will be empty.
In either case, you can add additional assets to the streams and even trim each clip’s start
and end points.
To add an asset to a stream
µ
Drag the video or audio asset from the Assets tab, the Palette, or a Finder window to the
stream where you want to place it.
With the V1 stream, DVD Studio Pro automatically ensures there is always a clip at its
beginning (if one has been assigned), and there are no gaps between the clips. With the
other video streams, the clips can only be positioned at markers. Audio and subtitle clips
can be positioned anywhere on the stream and there can be gaps between them.
Adding Audio Assets Automatically
When you enable the “Find matching audio when dragging” setting in the Track pane in
DVD Studio Pro Preferences, audio assets are automatically added to a track when video
is added.
When you add a video asset to the V1 stream, DVD Studio Pro checks to see if there is an
audio asset with the same base name in the same folder. If there is, it is automatically
added to the A1 audio stream.
The start of the audio clip will be the same as the video clip. If any audio already exists
in the A1 stream where the new audio clip needs to go, it is trimmed or moved as
necessary.
Note: Hold down the Command key after you start dragging to temporarily override the
“Find matching audio when dragging” preferences setting.
