To create a slideshow in iDVD:
Make sure the menu that the slideshow will be accessible from is showing in the iDVD window.
If you want the slideshow to link from the main menu, for example, the main menu should be showing in the iDVD window.
You can proceed in one of two ways:
Click the Add button in the lower left of the iDVD window, and select Add Slideshow from the pop-up menu. A button labeled My Slideshow appears on the menu.
Drag an album to the DVD menu. This automatically creates a button that links to the slideshow. The button has the name of your iPhoto album and, if the button is an image button, it automatically displays the first slide in the slideshow.
Double-click the button to open the slideshow editor.
The iDVD window changes to show the Photos pane if it is not already selected.
If you started by adding a My Slideshow button to your menu, the slideshow editor is empty, so you need to drag images to it from the Photos pane, described below.
If you started by dragging an album to your menu, the slideshow editor shows thumbnails of the photos in the slideshow. To view photos as a list instead, click the list icon in the upper right of the iDVD window.
Add, arrange, or delete photos or movie clips from the slideshow to create the sequence you want.
To add images, drag individual photos or folders from the Photos pane or from elsewhere on your hard disk or a connected server to the slideshow editor.
To add movies, drag individual movies from the Media pane or from elsewhere on your hard disk or a connected server to the slideshow editor.
To reorder the images or movies, select the ones you want to move, and drag them to a different position.
If you add a photo album and do not reorder the images, the slideshow displays your photos in the order they are organized in the photo album.
To delete an image or movie, select it and choose Edit > Delete, or press the Delete key.
Click the Settings button (shown below) and select the settings you want for the slideshow:
“Loop slideshow” makes the slideshow repeat continuously until the viewer moves to a different part of the DVD.
“Display navigation arrows” shows navigation arrows on the screen. It’s most helpful to display arrows when you set the slideshow to progress manually, which means the viewer controls movement from slide to slide. These arrows are simply a visual cue; the viewer must use the remote control to advance the slideshow.
“Add image files to DVD-ROM” adds copies of the photos and movies to the DVD disc so viewers can download them to their computers.
“Show titles and comments” lets you add titles and comments to the photos and movies. These are visible in the slideshow.
“Duck audio while playing movies” silences any soundtrack you have added to the slideshow while the movie in your slideshow play. This ensures that the slideshow soundtrack and movie audio do not play at the same time.
Click the Transition pop-up menu and choose a transition to smoothly move from one image to the next. Only one transition can be applied to a slideshow.
To preview a transition, click the Preview button (shown below). The iDVD remote control appears. Use your pointer to click the arrows in the remote control, which highlights buttons on your menu. Highlight the button to which you have added a transition and click Enter on the remote control. Click Exit to return to the slideshow editor.
Click the Slide Duration pop-up menu and choose the length of time you want each slide to stay on the screen. (You cannot set a custom duration time, and the duration you select applies to all slides in the slideshow.) Be sure to allow enough time for the transition you selected.
To let the viewer advance through the slideshow manually using a remote control, choose Manual. If you want to add a soundtrack to your slideshow, you don’t need to set the slide duration.
The slide duration you set does not apply to movies you add to the sideshow. Movies in a slideshow play in their entirety before the next slide appears.
Click the Return button to exit the slideshow editor.
