Then, in the Properties panel, click the Motion panel and drag the Audio pick whip to the audio file in the Project panel. • Drag the audio file from the Project panel to the menu in the Menu Viewer. Note: You link directly to the audio assets, not a timeline. Create video thumbnail buttons A button can contain a thumbnail image of the video to which it is linked. The image can be still or playing (animated). The Library panel includes predesigned video thumbnail buttons as well as menus with these buttons already in place. See also "Add a video background to a menu" on page 86 "Specify a link" on page 154 "About menu display time and looping" on page 90 "Animate video thumbnail buttons" on page 90 Video thumbnail button restrictions You need to understand the following concepts and restrictions when creating a video thumbnail: Placeholder determines size You use a single layer in a button layer set to serve as a placeholder for the video. The size of the placeholder image determines the size of the video displayed in the menu. If the image is not rectangular, Encore calculates the smallest rectangle in which the image could fit. Always rectangular, unless masked The video remains rectangular regardless of the shape of the image layer. However, you can overlay it with a layer (bitmap) or vector mask in Photoshop. A mask can hide portions of the image, forming a window through which the video plays. Layer name prefix (%) The placeholder layer must have the layer name prefix (%). The prefix includes the parentheses, for example, (%)Rigging. Destination timeline displayed A video thumbnail can display only the timeline to which it is linked, that is, its destination. You cannot play one timeline in the thumbnail and have the button lead to a different timeline. Also, until you link the button to the video, you see only the placeholder image. Still or moving The thumbnail video can be still or moving. Animating video thumbnails is a menu setting. All the thumbnails on a particular menu must be either still or moving. You set the animation by using the menu property called Animate Buttons. (See "Animate video thumbnail buttons" on page 90.) Looping or clipped A video thumbnail plays within the boundaries of the menu duration setting. For example, if the menu duration setting exceeds the length of the video thumbnail, the thumbnail loops, starting at the destination chapter (or poster frame if specified). You set the menu display time and looping of the entire menu in the Properties panel. (See "About menu display time and looping" on page 90.)
