Chapter 11: Sound effects and music 201
Switching audio tracks
Although the audio tracks do have their specialized
roles, as described above, these mainly control the
choice of track where new clips will appear. Original
audio will always be placed on the original audio track
when a new video clip is brought in; new voice-overs
will always be created on the sound effects and voice-
overs track; and new CD audio and SmartSound clips
will be added to the background music track.
Once a clip has been created, however, you can move it
to a different audio track if it is convenient to do so:
each track is actually able to accommodate any type of
audio clip. This gives you the flexibility to use two
sound effects simultaneously, for example, simply by
placing one of them on the background music track.
The only audio track with special status is original
audio, either for the main video track or, when it’s in
use, the overlay track. By default, audio clips on this
track are edited in parallel with the contents of the
video track at the same time index. To treat the audio as
a separate clip, lock the video track (by clicking the
padlock icon on the right side of the Movie Window).
See “Advanced Timeline editing” on page 87 for more
information.
The CD audio tool
Use this tool to create an audio clip from a CD
track. You can preview tracks within the tool,
and select either a whole track or an excerpt to add to
your movie.
