Interesting. In Photoshop you work with Keyframes. You just use one layer, set your first keyframe, drag the layer wherever and set the next kexframe. Than Photoshop crates the animation in between automatically. That is cool and easy for some projects. But this wouldn't work that way. That is why I asked. :)
Thanks for the great answer.
Yeah I've worked with keyframes before.. I find that if the program doesn't allow you to manually build the interpolation curve between your keyframes, then you're kinda stuck to a predefined set of animations.
Nice to know the diffs between these programs. Thanks!
