Reducing the Size of Media Files
Including large sound and movie les in a Pages document can make the entire
document le size very large. If you’re using only a portion of the sound or movie le
in your document can remove the unused portions of the audio or video le to make
the le smaller. You can choose either to reduce the size of individual media les or to
reduce the size of all the media les in the document that are not being used in full.
Before you reduce the movie or audio les, you must save them as part of your
document. For details about how to do this, see “Saving A Document on page 37.
Here are ways to reduce the le size of your document:
1 To reduce the size of an individual media le in your document, select a sound or
movie le for which you have set the Start and Stop sliders to exclude some part of
the le, and then choose Format > Image > Reduce Media File Size.
2 To reduce the size of all the media les in your document, make sure no sound, movie,
or image le is selected, and then choose File > Reduce File Size.
After reducing the size of your sound or video le, you won’t be able to restore the le
to its original length or listen to or view the parts that you have excluded. To restore
the entire le, you must add the le again.
Some types of movie les may not be reducible in this way.
To learn about reducing the size of image les, see Reducing Image File Sizes” on
page 142.
