A dilemma I've been faced with recently is how to storyboard busy animations. The goal is to provide stakeholders an early glimpse of what ideas an animation will convey without spending the development time to flesh it out completely. The downside is without the finer nuances of an animation's movement and timing the idea doesn't always get across.
Currently I'm using separate PowerPoint slides to storyboard each significant change in the animation. This works great if the animation is simple like a bullet appears along with a corresponding image. But something more complex like a box that grows overtime as dollar signs fall into it is more difficult and risks the stakeholder missing the point.
I guess I could use PowerPoint animations. Although the last stakeholder review used printouts, and I often end up animating in Flash. Maybe I need to branch out into industries to research... look at some Disney cartoon storyboards or something.
Any other suggestions? How do you storyboard animations?
