I have been wondering what people use to prototype or mock up design animations or transitions. After Effects seems like a pretty standard way to mock up quick animations and such. Obviously trying to figure it out in the browser would be the best solution but giving the developers and designers an idea of what a “best case” animation looks like is preferable at times. Poking around in the code isn’t the fastest way to figure out that stuff.
Anybody have any preferences or tools they use?
