About menu display time and looping
The default display setting for a still menu is Hold Forever, which displays the menu indefinitely. You can limit the menu active time and the timeout action if the user doesn’t act when the menu is active. You limit the menu display time in videos that many users view, such as in information kiosks. When one viewer leaves, the video returns to the main menu so that it is ready for the next viewer.
Three settings control the display time and looping of a motion menu: Duration, Loop #, and Loop Point.
About Loop # and Duration
You can set the display time of a menu to a specific amount (called Duration). For motion menus, the Duration setting determines how long the menu plays before either repeating itself (defined by Loop #) or triggering the end action. The video or audio content of the menu plays within the confines of the Duration. The menu duration is set automatically to match the length of the video background or audio that you add to the menu. If the run time of the video or audio content exceeds the menu duration, the content is clipped. If the run time of the video background or audio is less than the duration, the content ends. (The background displays the last frame until the menu loops or ends.) For animated thumbnail buttons, if the run time of a video thumbnail button is less than the duration, it repeats until the menu loops or ends.

About Loop Point
You can set motion menus to loop either a specific number of times or until the viewer activates a button (forever). When looping, all content begins again once the menu duration is reached. You specify a loop point to begin looping a point different from the starting point.
The loop point is used to initially disable the buttons. Until the loop point is reached, the viewer cannot select or activate a button. The menu returns to this point on each repetition, so the buttons are disabled only when the menu is first displayed. For any subsequent repetitions, the Duration is shorter and the start point of all video content in the menu is offset.

A loop point is often used when a menu has been animated in Adobe After Effects®. For example, you can create a video in After Effects in which the button images fly in from different points and settle into position after 15 seconds. In this case, the background video, not the menu, includes the button images. Except for those first 15 seconds, the button images would remain static for the remainder of the video (other elements could continue to move). The actual menu that uses this animation as its background could be simple. It would need just a placeholder background layer (to be replaced by the video) and button layer sets that contain only the button subpicture layers used for the selected and activated button states. (See About creating menus in After Effects.)
For the first 15 seconds that the menu is displayed, the buttons perform their animation. If you set the loop point to 15 seconds, you then disable the buttons during the animation. Only when the menu reaches the loop point do the buttons become active. If set to loop, it loops back to the loop point, not the beginning of the animation.
Set menu display time and looping
The Properties panel contains several options that control the display time and looping of a menu. The options you choose depend upon whether you created a still or motion menu. These options control whether video, audio, or thumbnail buttons play while the menu is displayed.
In the Project panel, select the desired motion menu.
In the Properties panel, click the Motion tab, and then do one or more of the following:
To set the menu display time to a fixed amount, enter a value for Duration.
To have the menu loop a set number of times, select or type a value for Loop #.
To have a menu loop until the viewer activates a button, select Forever from the Loop # menu.
To disable the menu buttons for a set amount of time, type a timecode value for Loop Point.
If you set the menu to display for a set duration or number of loops, the menu must have an end action. Click the Basic tab and specify a destination for End Action so that the menu has a destination once it times out.
Set menu loop back
Select the menu from the Menu panel.
On the Properties panel, set the loop point.
Select Specify Link from the End Action Options menu.
Select the target from the list, and then select Set To Loop Point, and click OK.
