实时改变影片帧频-ActionScript 3 Tips and Tricks
由于ActionScript 3 Tip of the Day(ActionScript3 Tips and Tricks)一文原帖地址实在太慢，准备从今天起，慢慢将原帖转到Blog上，以免以后哪天原帖不能访问了，我还可以拿来参考。
实时改变影片帧频(Change the frame rate of your movie)
Using ActionScript 3, you can dynamically change the frame rate of your movie using the Stage class.
The Stage class (flash.display.Stage) is the class assigned to the stage object which is accessible from your main movie sprite/movie clip (or others within the same security sandbox) using the stage property. The stage object has a frameRate property which can contain any value between 0.01 and 1000 and determines the frame rate at which the Flash player plays back your movie. Changing this value lets you change the frame rate at runtime.
