Creating a video thumbnail buttonA button can contain a thumbnail image of the video to which it is linked. The key is to create a video thumbnail layer with the layer name prefix (%). The image on the layer serves as a placeholder for the video. The video remains rectangular regardless of the shape of the image layer. You can, however, use masks to overlay the thumbnail. The size of the image determines the size of the video displayed in the menu. (If the image is not rectangular, Adobe Encore DVD calculates the smallest rectangle in which the image could fit.) Until you link the button to the video, you see only the placeholder image. The thumbnail image can be still or moving. Turning video thumbnails on or off is a menu setting. All the thumbnails on a particular menu must be either still or moving. You set the video on or off using the Animate Buttons option in the Properties palette (Menu mode). When the Animate Buttons option is off, the thumbnails display a frame of the video. See Animating video thumbnail buttons. You can designate a specific frame using the Poster option in the Chapter mode of the Properties palette. |
