Animate video thumbnail buttons You can set video thumbnail buttons to be either still or moving using the menu property Animate Buttons. When you select the menu property, you convert all the video thumbnail buttons on the menu to motion buttons. Thus, each time the viewer displays the menu, the video links play in the thumbnails. When Animate Buttons is deselected, the thumbnails display a still frame of the video. 1 In the Project panel, select the menu containing the video thumbnail buttons. 2 In the Properties panel, click the Motion tab and select Animate Buttons. The Animate Button property controls the state of all the video thumbnail buttons on the menu. You cannot set them individually. Encore composites the video into the button during the build process. To preview the animated buttons, you need to render the menu first. See "Preview motion menus" on page 171 for information. See also "About menu display time and looping" on page 90 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 how long a menu waits for the viewer to activate a button, and you can designate what should display next if the viewer makes no selection. Controlling the display time of a menu is usually necessary in videos left running to be viewed by many people, such as in information kiosks, museum displays, or educational settings. When one viewer leaves, it is important that 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. Menu display time and looping options in Properties panel 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.
