Sound and Synchronization 329
To use cue points:
1
Place cue points in a sound file or (on the Macintosh only) in a QuickTime file.
Use an audio-editing program to define cue points in sounds and digital videos.
2
Import the sound or digital video into Director.
Note: Digital video is always linked, whether you select the Standard Import option or the Link to External File
option in the Import dialog box.
3
Place the sound or digital video in a channel in the Score, and extend it through all the frames
in which you want it to play.
4
Double-click the frame in the tempo channel where you want the playhead to wait for a
cue point.
5
In the Tempo dialog box, select Wait for Cue Point.
6
Select the sound or digital video from the Channel pop-up menu.
7
Select the desired cue point from the Cue Point pop-up menu.
Select the End or Next cue point or any named or numbered cue point in the sound or digital
video. Director recognizes the end of a sound, regardless of whether you’ve defined cue points.
When the movie plays, the playhead pauses at the frame until the cue point passes.
Synchronizing sound with Lingo
By writing Lingo that performs an action when a cue point is reached in a sound or QuickTime
file, you can synchronize a movie with sound or digital video. For more information on each of
these functions and properties, see the Lingo Dictionary.
•
To set up Lingo that runs when the movie reaches a cue point in a sound or QuickTime file,
put the Lingo in an
on cuePassed
handler.
•
To determine whether a sound or QuickTime file has passed a specific cue point, use the
isPastCuePoint()
function.
•
To find the ordinal number of the last cue point passed in a sound or QuickTime file, use the
mostRecentCuePoint
function.
•
To obtain a list of names for the cue points in a specific sound or QuickTime file, test the
cuePointNames
property.
•
To obtain a list of times for cue points in a specific sound or QuickTime file, test the
cuePointTimes
property.
Accessibility
With Lingo and behaviors, you can provide captioning to help users with hearing impairment
experience the audio portions of your movies. For more information, see Chapter 23, “Making
Director Movies Accessible,” on page 551.
