The frame rate (the speed at which the animation in Adobe Flash Professional is played) is measured by the number of frames per second (fps). A frame rate that is too slow makes the animation appear to stutter (stop and start), while a frame rate that is too fast blurs the details of the animation. A frame rate of 24 fps is the default setting for new Flash documents and usually gives the best results on the web. (The standard rate for motion pictures is also 24 fps.)
The complexity of the animation and the speed of the computer playing the animation affect the playback's smoothness. To determine optimum frame rates, test your animations on a variety of computers with different processing capabilities.
Because you specify only one frame rate for the entire Flash document, be sure to set the desired frame rate before creating your animations.
The frame rate essentially determines the rate at which the playhead moves across the Timeline.
To set the frame rate, do one of the following:
To learn more about setting the frame rate of a Flash project, see the section titled Animation frame rate and performance in the Flash documentation.
