The screencast videos below give you an overview of how to use iMovie ’09 to make CDS-Style digital story. The first video shows you how to create a new iMovie project, import photos, import audio, and add title cards. The second video shows you how to add subtitles and transitions, adjust the appearance of photos, set the length of time for each photo to display, and export the digital story so that you can share it with your classmates. (Note: The video doesn’t show this option, but you can also export your file in QuickTime format, if you’d prefer to use that instead of m4v format.)
The videos present these steps in the order I recommend you follow when you create your own project. Waiting until towards the end to add transitions and adjust how long each photo or card displays on the screen will save you some headaches, although keep in mind that this can often be the most time consuming part of the process, as you try to adjust the photos to line up with your audio narrative.
