Controlling QuickTime with Lingo or JavaScript syntax

Page 265 highlights

ADOBE DIRECTOR 11.0 254 User Guide Center is available only if Crop is selected. It determines whether transformations occur with the cast member that is centered within the sprite or with the cast member's upper-left corner aligned with the sprite's upper-left corner. Scale fits the movie inside the bounding rectangle. 8 To determine how the video plays back, set the following options in the upper portion of the window: Video displays the video portion of the digital video. If this option is turned off, the video portion does not play. Deselect this option and select Sound if you want to play only the audio portion of a movie. Audio plays the sound portion of the digital video. DTS (Direct To Stage) lets QuickTime drivers installed on the computer completely control the video playback. For more information, see Playing digital video Direct To Stage. Controls displays a controller bar at the bottom of the video if Direct To Stage is selected. Paused stops the digital video when it first appears on the Stage (while playing the Director movie). Loop replays the digital video continuously from the beginning to the end. Streaming begins playing the video while the rest of the video continues to load from its source. 9 If Direct To Stage is selected, select an option from the Playback menu to specify how to synchronize the video to its soundtrack: Sync To Sound makes the digital video skip frames (if necessary) to keep up with its soundtrack. The digital video might also take less time to play. Play Every Frame (No Sound) makes every frame of the digital video appear but does not play the soundtrack because the video cannot play the soundtrack asynchronously while the video portion plays frame by frame. Depending on the data rate of the digital video, the sprite might play more smoothly with this option selected, but this is not a certainty. In addition, playing every frame might cause the digital video to take more time to play. 10 If Play Every Frame (No Sound) is selected, select the following options from the Rate menu to set the rate at which a digital video plays: Normal plays each frame at its normal rate, and no frames are skipped. Maximum plays the movie as fast as possible while still displaying each frame. Fixed plays the movie using a specific frame rate. Enter the number of frames per second in the field at the right. Use this option only for digital videos that use the same frame rate for each frame of the movie. Controlling QuickTime with Lingo or JavaScript syntax Use Lingo or JavaScript syntax to control a QuickTime video's appearance and sound volume. For QuickTime VR, you can use Lingo or JavaScript syntax to pan a QuickTime VR digital video and specify what happens when the user clicks or rolls over portions of the video. You can set the rotation, scale, and translation properties for either a QuickTime cast member or a sprite. For more information, see the Scripting Reference topics in the Director Help Panel. • To determine whether a cast member or sprite is a QuickTime VR digital video, test the isVRMovie property.

Center
is available only if Crop is selected. It determines whether transformations occur with the cast member
that is centered within the sprite or with the cast member’s upper-left corner aligned with the sprite’s upper-left
corner.
Scale
fits the movie inside the bounding rectangle.
8
To determine how the video plays back, set the following options in the upper portion of the window:
Video
displays the video portion of the digital video. If this option is turned off, the video portion does not play.
Deselect this option and select Sound if you want to play only the audio portion of a movie.
Audio
plays the sound portion of the digital video.
DTS (Direct To Stage
) lets QuickTime drivers installed on the computer completely control the video playback.
For more information, see
Playing digital video Direct To Stage
.
Controls
displays a controller bar at the bottom of the video if Direct To Stage is selected.
Paused
stops the digital video when it first appears on the Stage (while playing the Director movie).
Loop
replays the digital video continuously from the beginning to the end.
Streaming
begins playing the video while the rest of the video continues to load from its source.
9
If Direct To Stage is selected, select an option from the Playback menu to specify how to synchronize the video
to its soundtrack:
Sync To Sound
makes the digital video skip frames (if necessary) to keep up with its soundtrack. The digital
video might also take less time to play.
Play Every Frame (No Sound)
makes every frame of the digital video appear but does not play the soundtrack
because the video cannot play the soundtrack asynchronously while the video portion plays frame by frame.
Depending on the data rate of the digital video, the sprite might play more smoothly with this option selected,
but this is not a certainty. In addition, playing every frame might cause the digital video to take more time to play.
10
If Play Every Frame (No Sound) is selected, select the following options from the Rate menu to set the rate at
which a digital video plays:
Normal
plays each frame at its normal rate, and no frames are skipped.
Maximum
plays the movie as fast as possible while still displaying each frame.
Fixed
plays the movie using a specific frame rate. Enter the number of frames per second in the field at the right.
Use this option only for digital videos that use the same frame rate for each frame of the movie.
Controlling QuickTime with Lingo or JavaScript syntax
Use Lingo or JavaScript syntax to control a QuickTime video’s appearance and sound volume. For QuickTime VR,
you can use Lingo or JavaScript syntax to pan a QuickTime VR digital video and specify what happens when the user
clicks or rolls over portions of the video.
You can set the rotation, scale, and translation properties for either a QuickTime cast member or a sprite. For more
information, see the Scripting Reference topics in the Director Help Panel.
To determine whether a cast member or sprite is a QuickTime VR digital video, test the
isVRMovie
property.
