Apple DVD Studio Pro 4 - Manual (Page 294)

Clicking the button starts motion menu playback. Clicking it a second time stops playback.
You can also press Command-J to turn the playback on and off.
Unlike a similar button in iDVD, this button does not determine whether or not this menu
is a motion menu. It only controls whether the motion menu plays while you are working
on it. Once you add motion assets to a menu, it is a motion menu.
Note: Depending on your system and the number of motion items in the menu, motion
menu playback may not be perfectly smooth in the Menu Editor. Once you build your
project, playback will be perfect.
About the Motion Settings
The Menu Inspector’s General tab contains a section for configuring a menu’s start, end,
loop, and duration times.
You can drag the slider located under the thumbnail images of the background, click the
arrow controls, or enter a timecode value for each of the entries. The way the Start, Loop
Point, End, and Duration settings function depends on the type of assets assigned to the
menu.
Start Setting
You can use the Start setting to set the video’s starting frame. By default, the start is set
to the background video’s first frame. If there is audio assigned to the menu, its start time
is also moved by the same number of frames as the video.
Note: If there are other motion assets assigned to buttons or drop zones, they are not
affected by the change in start time.
When the menu’s background is a still image, the Start setting only affects the menu’s
audio.
Loop Point
You can use the Loop Point setting to set a frame different from the starting frame to use
when you choose Loop as the At End setting. By default, the Loop setting is the same as
the Start setting. When you adjust the Loop setting, you are choosing the frame that is
jumped to once the end frame is reached. This allows you to have a looping background
with a beginning section—for example, a fade up from black or a transition from another
menu—that only plays the first time through. If there is audio assigned to the menu, it
automatically follows the video as it loops.
