Figuring Frame Rates - Page 2

Flash creates compact web animations so a trade off occurs - smaller file sizes and less CPU intensive movies for slightly chunkier animations. At 12 fps, the end result is still pretty good. What will determine the quality of your movie on the web will be the complexity of the animation and the speed of the computer on which the animation is being played on.

Sure, you can bump it up to 30 fps, but beware, if you have a groovy but CPU intensive animation many of your visitor's computers will grind away leaving them most unsatisfied - thus defeating the reason why you are using flash in the first place. You could use a preloader which would take out the bumps caused by a slow download but the CPU issue remains. (I can hear all those artist's hearts breaking :)
