Framerate

The Framerate setting controls how many frames per. second will be displayed while your video is playing. The exact numbers available for you to choose from will be dependent on the framerate of your original video, but you'll usually have two options that amount to full-rate or half-rate. Typically, you'll want the highest framerate possible. However, if you are making videos for small, portable, slow devices like PDAs or cell phones, you may want to drop the framerate to make sure that the player will be able to keep up. The result might not look as smooth but at least it will play.
