Adobe Encore and Customizing Video Thumbnails
The easiest way to create a video thumbnail button is to drag a button from the Library panel into your menu and then edit the button. (Many menus in the Library panel already include video thumbnail buttons.) These buttons are sized appropriately, contain a placeholder image with the appropriate layer name prefix (%), and include pre-designed button sub-pictures, which change the appearance of the button when selected and activated by the viewer.
1. Open the menu to which you want to add video thumbnail buttons.
2. In the Library panel, click the Show Buttons icon to display the predesigned buttons.
Drag the desired thumbnail button from the Library panel to the Menu Viewer. Repeat until you have placed all the thumbnail buttons you need.
3. To resize the thumbnail buttons, select the button layer sets in the Layers panel (Shift-select to select more than one). Then, using the Selection tool , Shift-drag a corner selection-handle of one of the buttons until they are the desired size. (Using the Shift key while dragging resizes the buttons proportionally so that they maintain their aspect ratio.)
4. Link each button to the appropriate item, such as a timeline or slide show. The text in the button is updated with the name of the linked item. You can also use the Text tool to select and edit button text.
