Creating thumbnails with interesting shapes
Adobe Encore DVD creates thumbnails as rectangles, to match the frame of the video. To display a
thumbnail with a more interesting shape, such as the ovals you're using in this project, first make a
rectangle and then mask it.
In Photoshop, when you create a video thumbnail button with a nonrectangular shape, the actual
thumbnail layer should be rectangular. If the layer is not rectangular, Adobe Encore DVD calculates
the smallest rectangle in which the image could fit. The video remains rectangular regardless of the
shape of the image layer.
This button was created with an elliptical layer.
You can, however, use vector masks or layer masks on the thumbnail layer to create a nonrectangular
shape. The size of the image determines the size of the video displayed in the menu.
This button was created with a rectangular layer and an elliptical vector mask.
