Keeping Media with Your Presentation

You may have noticed that Keynote took a while to save your presentation file after you added the movie file. This is because Keynote (by default) copies all of the media used in your presentation into the Keynote file. This is a good idea because it simplifies the process of transporting your presentation to another Mac. It means that when you take your Keynote presentation on the road, you have to take only one file with you. Let's check that all of the elements made it into your presentation file for backup.

Note

Fonts used in a presentation must also be installed on the presentation machine. If you use fonts that are not installed with iWork '06 or that are not OS X system fonts, be sure to install the needed fonts on the new system. Fonts, however, are not saved in the Keynote package. Any fonts used in a Keynote project on one machine need to be installed on any new system where the project will also be used.

1.	In Keynote, choose Keynote > Preferences.

2.	Click the General button and make sure that all three check boxes in the Saving area are selected. Checking these options ensures that a backup file is created each time you save. The backup is stored in the same folder as the original. This is a good idea in the rare case that your project file becomes corrupted. Similarly, it's a good idea to copy both audio and movie files as well as theme images into the document. This is a good idea for both backup purposes and portability of your project file.
3.	Close the Preferences window.

Tip

If you ever need to access an element from a presentation and don't have access to the original files, you can borrow it from Keynote. Control-click (or right-click if you have a multi-button mouse) the Keynote document and choose Show Package Contents. The folder contains all of the elements of your presentation. You can Option-drag any of the elements to a new folder to copy them.

Adding animation to your slides is an important step in finalizing a presentation. You can create several types of animation in Keynote. Two of the most common are builds and transitions.

In Keynote, a build allows you to animate the appearance of text or slide elements. You can create dynamic builds that control the order in which information is revealed on a slide. This ordering of information can help your audience, as it directs them where to focus their attention. Keynote harnesses the power of your computer's graphics card to create television-quality animations.

The text on this slide is being animated with a Character Dissolve build. We'll use this animation later in the lesson.

Transitions between slides can also aid your audience. Transitions are meant to signify a change in topic for your audience. Keynote offers several options to choose from, but it is considered good design to limit yourself to just a few in a presentation. Learning how (and when) to add transitions can really enliven your presentation.
