Reducing the Size of Media Files
Including large sound and movie les in a Numbers spreadsheet can make the entire
document le size very large. If you’re using only a portion of the sound or movie le
in your spreadsheet, you can remove the unused portions of the audio or video le to
make the Numbers 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. Choose File > Save, click Advanced Options, make sure that “Copy audio
and movies into document” is selected, and then click Save. For more details about
saving spreadsheets, see “Saving Spreadsheets” on page 32.
Here are ways to reduce the le size of your spreadsheet:
To reduce the size of an individual media le in your document, select a sound or m
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.
To reduce the size of all the media les in your document, make sure no sound, movie, m
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 195.
