Chapter 6 Adding Sound and Movies 111

When your movie plays during your slideshow, playback controls appear when you

move the pointer over the movie. To learn more about controlling the playback of your

audio or movie during your presentation, see “Playing Movies” on page 213 .

Reducing the Size of Media Files

Including large sound and movie les to your Keynote 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 slideshow, you can remove the unused portions of the audio or video le to

make the Keynote document 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 (including masked or resized image les).

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 Presentation” on page 31.

To reduce the le size of your document, do either of the following:

m To reduce the size of an individual 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, or an

image le that you have masked or resized to a smaller size, and then choose Format >

Image > Reduce Media File Size.

m 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. If you’ve

reduced the size of a masked or resized image le, you won’t be able to restore the

image to a larger size without losing some image quality.

If you change your mind and later want to restore the entire le, you must add the le

to your slide again.

Some types of movie les may not be reducible in this way.
