| Keynote allows you to export your presentations as QuickTime movies, which can be quite helpful. As a QuickTime movie, the presentation can be played on Macs that don't have Keynote installed. QuickTime movies can also be played on Windows and Linux machines. Keynote files exported as QuickTime movies include all the transitions and animated object builds that you added to the presentation. Another benefit of a Keynote file exported to QuickTime is that you can create a self-running QuickTime movie, which is useful for unattended presentations that don't have Keynote installed, such as kiosks . When you create a self-running QuickTime movie, you can set the duration for object builds and how long a slide is visible. If you prefer, you can instead create an interactive QuickTime movie, which allows your viewers to advance through the slide builds and slides manually. To create a self-running QuickTime movie | 1. | Open the Keynote file that you wish to export to a QuickTime movie.
| | 2. | Choose File > Export. The Export sheet slides down from the top of the document window ( Figure 11.27 ). By default, QuickTime is selected.  | | 3. | Click Next . The QuickTime Export sheet appears ( Figure 11.28 ).  | | 4. | From the Playback Control pop-up menu, choose Self-Playing Movie.
| | 5. | If you want to change the slide duration (the length of time a slide is displayed after it is fully built) from its default value of 10 seconds, enter a new value.
A slide's duration does not begin until all of the object builds on the slide are complete.
| | 6. | Enter a value in the Build Duration field, if you want to change it from the default duration of three seconds.
By default, there is no delay between the moment a slide first appears on the screen and when the first object build begins. You can add a delay in the Build Inspector. The Build Duration field controls the number of seconds between the beginning of one build and the next. So, for example, if there is no delay entered in the Build Inspector, when the presentation switches to a slide that has an object build, the first build will trigger immediately, the next build will occur according to the number you chose in the Build Duration field, and subsequent builds will also take that long.
| | 7. | From the Repeat pop-up menu, choose one of the following: -
None means that the slideshow will play through only once. -
Loop makes the slideshow play continuously, beginning again automatically when it reaches the end. -
Back and Forth makes the presentation play through once, then, when it reaches the end, begin to play backwards . | | 8. | From the Formats pop-up menu, choose one of the following presets: -
Full Quality, Large uses the Sorenson Video 3 video compressor, at 24 frames per second (fps), and produces movies that are the same size as your slides. Use this one for the highest quality presentations. The trade-off is that this option creates the largest files. -
CD-ROM Movie, Medium uses the same video compressor at 12 fps, and the movie is half the size. So if your slides are 800x600, the movie will be 400x300. -
Web Movie, Small uses the same video compressor and 12 fps, but the movie is one-quarter the Large size. | | 9. | If you have audio in your presentation, and you want it included in the exported movie, make sure the Include audio check box is selected.
| | 10. | Transparency is an advanced feature that is useful for exporting movies that will later be used in editing programs such as Final Cut Express. If you don't intend to use your movie in this fashion, leave Include transparency unchecked.
| | 11. | Click Next.
A Save sheet appears, prompting you for the name of the exported movie and where you want to put it on your hard disk.
| | 12. | Click Export. The Export to QuickTime window appears, and shows you a preview of the slideshow as it is exported ( Figure 11.29 ). When the export is complete, the window disappears.  |  Tips -
The size of the exported file is dependent on the quality you use for export. For example, I exported a small (8 slides) file that had transitions and object builds in the Large, Medium, and Small sizes. Respectively, the sizes of the exported QuickTime files were 12.8 MB, 1 MB, and 636 KB. If you will be using your presentation on the Web, you should carefully balance the size of your presentation with the quality you need. -
Depending on the speed of your Mac, the size of the presentation, and the settings you chose from the Formats pop-up menu, the export could take up to several minutes to complete. -
Keep in mind that if you include audio in your presentation it can significantly increase the file size, especially if you have a soundtrack throughout your slideshow.

See the previous section for an explanation of these options.
| | 6. | If you have audio in your presentation, and you want it included in the exported movie, make sure the Include audio check box is selected.
| | 7. | Unless you plan to use the exported movie in a video editing program, leave the Include transparency check box unselected .
| | 8. | Click Next.
A Save sheet appears, prompting you for the name of the exported movie and where you want to put it on your hard disk.
| | 9. | Click Export.
The Export to QuickTime dialog appears, and shows you a preview of the slideshow as it is exported.
| Tips -
By default, interactive movies will not show the familiar QuickTime movie controller in either a browser or the QuickTime Player. You can change that by downloading a package of QuickTime AppleScripts from www.apple.com/applescript/quicktime/. Among the many AppleScripts in this collection is one called Set Controller Type . Double-click the script, and you'll see a Set Prefs button. Click this button, and in the resulting dialog set the controller type to Standard. Then, in the Finder, drag the exported movie onto the Set Controller Type script icon. The script will run and enable the controller. Self-playing movies will always show the controller. -
I found a small bug in the Set Controller Type script mentioned above, so I have fixed it and uploaded the fixed script to this book's companion Web site, at www.negrino.com/keynote2/. Feel free to download the script from that page instead. -
In the QuickTime Player, you step through an interactive presentation by using the spacebar or right arrow key to go forward, and the left arrow key to go back. -
If you have QuickTime Player Pro installed on the machine you are using to play back the presentation, you can play back using the full screen. See "Using QuickTime Pro" in Chapter 6 for more information. -
If you want to embed the QuickTime file into a Web page, you can turn off the movie controller (the part of the window with the Play button) as part of your HTML. The user will still be able to step through the show by clicking on the movie.
| It is possible to change the export settings in the QuickTime Export sheet to more precisely control the video and audio formats used in the QuickTime movie. You can change the type of video compression used (called the video codec ), and also change the audio codec. To change these settings, choose Custom from the Formats pop-up menu. The Custom QuickTime Settings dialog will appear ( Figure 11.30 ). You can use this to create a custom size for your movie, or you can change the compression scheme by clicking the Settings button in the Video section, which brings up the Compression Settings dialog ( Figure 11.31 ). You can then choose a video codec from the pop-up menu at the top of the dialog. Different codecs have different settings that will appear. There is a preview area that will show you the effects of your changes. 
Clicking the Settings button in the Audio section brings up the Sound Settings dialog ( Figure 11.32 ), which allows you to select an audio codec. 
Just because you can change the settings from the presets doesn't necessarily mean that you should, however. The presets produce files that look quite good, and will suffice for the vast majority of your export needs. But if you are familiar with the effects of the different QuickTime video and audio codecs and are confident that you can improve on Keynote's presets, you have the power. |
