Compressing Media
Compressing Media
A presentation that contains large video and sound fi les can take up a lot of disk space. If
you have plenty of room on the disk you will be using to transport the presentation, great.
But if you will be distributing the presentation in a situation where size is limited, such as
via an e-mail attachment, you might want to consider compressing the media.
Compressing media decreases its quality so that it takes up less space. Sounds may be less
crisp, and videos may lose sharpness in both picture and sound. It’s a trade-off, therefore,
between size and quality. Each situation will be different in determining the appropriate
balance.
To compress media, follow these steps:
1. (Optional) Make a backup copy of your presentation file in case you don’t like
the decreased quality of the clips after compression and want to revert to your
original version.
2. Choose File
Compress Media. (If that command doesn’t appear on the Info tab,
you don’t have any compressible media in your presentation.)
3. Choose a quality level: Presentation Quality, Internet Quality, or Low Quality.
See Figure 20.8.
A Compress Media dialog box appears showing the compression progress.
