Not to be nit picky, but just so you don't buy something you may not need or want right now, After Effects is not an editing program, it's a compositing program which allows you to add special affects via layers like Photoshop. An example of an editing suite (or NLE) is Sony Vegas, Adobe Premiere Pro, and some others. Now don't get me wrong, AE is a great product which I use myself. However, I'm not sure how experienced you are with editing and didn't want you to spend hundreds of dollars on a program. If it's an editing program you're looking for and nothing else, look into the Sony Vegas Platinum Studio. It has some effects and is only about $120. Not sure if they make a MAC version though. Anyway, from there, you can figure out if you want something more powerful like Premeire Pro or AE. So, I apologize in advance if you already knew this info, but just trying to look out for ya.
