Apple DVD Studio Pro 4 - Manual (Page 361)

The transition clips use a start and end video frame, with the transition controlling how
the video changes from one to the other.
• The start frame: This is the menu with all buttons in the normal state. If the menu has
a video asset as its background, the loop point frame (or first frame, if the loop point
is not set) of the video is used as the start frame. The start frame also includes the
menu’s drop zones and text objects.
• The end frame: This is the first frame of the target the button is jumping to. If the button
jumps to a script, the end frame is black. If you change the button’s target, the end
frame automatically updates.
You are able to assign specific assets or colors as the start and end video frames in the
Menu and Button Inspectors. See
Transition Tab in the Menu and Button Inspectors for
more information.
The transition clips that are created with the menu transition feature are rendered as part
of the build process. They are placed in the same video title set (VTS) file as the menus.
When authoring a project that will fill the DVD disc, you must take into account that a
transition video clip is rendered for each menu button that has transitions enabled—a
menu with 18 buttons can require 18 transition video clips. This can have a significant
impact on the amount of disc space the menus require. See
Transitions for more
information.
Video Transitions
When you choose Video Transition from the Transition pop-up menu in the Transition
tab in the Menu or Button Inspector, you can assign a short video clip to be used as the
transition clip.
Adding Button Transitions to a Menu
You can set a default transition for the menu. This transition is applied to all buttons.
To set a transition for a menu
1 Select the menu in the Outline tab, the Graphical tab, or from the Menu Editor’s View
pop-up menu.
2 Click the Transition tab in the Menu Inspector.
3 Choose either a Standard Transition or the Video Transition from the Transition pop-up
menu.
You can choose “not set” to disable default transitions for this menu. (You can still
configure individual buttons to use transitions.)
4 Configure the transition using its specific parameters.
Once you have configured the menu’s transition, you can modify or disable it at each
button.
