Does anybody know how to accomplish any of the effects in this trailer, if you each help with one, that would make my day.
I didn't see any "effects" but I did see basic keyframe animation. The spin effects are simply a 3D layer with rotation keyframes on the Y axis. The little splashes when the duck hits the water surface are nothing more than traditional animation. If you go to the front page of this forum and look at the top you'll find a link to both the help and the FAQs pages. I'd start with Getting Started.
