I would like to be able to animate the UI that i have created in Photoshop so i can demonstrate it to people. I believe this can be done in After Effects but am not quite sure how to go about doing so. Some tips or advice (or even video tutorials) would be helpful and much appreciated. A good example for what i would like to do is seen here
When you mean animate are you asking how to move/scale the screen/video within the phone? If that's the case I'd suggest you check out After Effects Basic Training from Video Copilot. That should teach you what you need to do this project and if you get stuck on something specific, just ask.
