Chapter 7. Creating Cool Effects with Text > Alpha Transparency and Brightness

Alpha Transparency and Brightness

You can use alpha transparency and brightness to create interesting effects. Changes in the alpha transparency can be used to make text fade in or fade out. At intermediate settings, you can use alpha transparency to complement other elements in a movie.

Brightness adjusts the relative lightness or darkness of the image from black to white. On a black or white background, you can use brightness as an alternative to changing the alpha transparency. The bonus is that brightness changes are far less CPU-intensive than alpha changes.
