As you'll soon see, the new Adobe Title Designer can add a sheen to any title object. But because you can't animate the sheen property itself, you'll have to take a more indirect route to make the sheen appear to move. The trick is to create two elements, known in video as a matte and a fill. A white-on-black title serves as the matte, which will effectively key out, or cut a hole in the video. You'll fill this hole with another titlethis time, a rectangle containing the color and sheen you want the title to have. This way, you can animate the fill by applying a motion setting to it. When you combine, or composite, the matte, fill, and background clip using a transparency technique called a track matte, the shiny highlight will appear to sweep across the surface of the title.
