Specifying Acrobat 6.0-compatible media properties
You can change the appearance of the play area, specify whether the media clip is played
back once or continuously, and set a number of other properties. One advantage to using
Acrobat 6.0-compatible media clips is that you can set up a list of alternate renditions.
That way, if a high-resolution movie can't be played on the user's system, or if the
assigned player isn't available, the next available rendition of the movie can be played
instead.
To change media properties:
1. Select the Movie tool , the Sound tool , or the Select Object tool , and then
double-click the play area.
2. Click the Settings tab in the Multimedia Properties dialog box, and do any of the
following:
●
For Annotation Title, specify the title of the movie. This title does not determine which
media file is played.
●
For Alternate Text, type a description of the media file that may be read aloud for visually
impaired viewers.
●
To change media settings, such as showing player controls and setting the volume level,
select the media clip rendition, and then click Edit Rendition. Select the desired settings in
the Edit Rendition dialog box, and then click OK to return to the Multimedia Properties
dialog box. (See
Rendition settings .)
●
To add alternate renditions, such as low-resolution files, click Add Rendition. (See
Adding and editing renditions .)
3. Click the Appearance tab, and then select options to determine the border appearance of
the play area. Click Change Poster Option to change the poster that appears in the play
area.
4. Click the Actions tab, and then define new actions for the various mouse movements. (See
Using actions for special effects .)
5. Click Close.
