Flash offers several ways of dividing movies in time. Which you select depends on various factors, including which makes sense intuitively, whether and how you intend to implement ActionScript in the movie, and even more broadly, how you intend to architect the overall project.

Tip

Flash documents can have a maximum of 16,000 frames per timeline.

If you are an animator, and you are developing cartoons meant to be played from beginning to end in order, without user interaction, the traditional division of the timeline into scenes is probably a good option. Using Flash scenes, you can break the timeline into arbitrary sections, working on one at a time. At runtime, Flash plays the scenes back, without interruption, in order (though you can reorder scenes, as needed). From the point of view of ActionScript and Flash movie architecture, scenes are primitive and generally more trouble than they are worth.
