What is Adobe After Effects?

I have question, about Adobe Effects. What is Adobe Effects used for, per say in a vid? I know some vidders use it, I know in part it's to create motion graphics(am I wrong)? Apologies if this has been asked before.

I'm no expert on AE -- still definitely consider myself to be in the process of learning it and picking up new ways to apply it in vidding as I go. Thus far, I've used it for opening titles, ripple effects (the effect controls were a lot more precise than what Premiere had to offer) and speed ramping (when you want to be able to vary the rate of speed of a clip over time, rather than just doing a flat percentage speed change).

After effects is used to do things like rotoscoping, where you can mask out clips over layers of video like you would a still image in photoshop. You can see an example of it in my vid Colorblind (http://blackbird-films.com/musicvids/veronicamars-colorblind.zip) Think of the movie Pleasantviller where the world was black and white but then one person was in color. That's rotoscoping.

You can also do green screen type stuff where you put somethign in front of a different moving background (not just a still photo) and you can do more complicated picture in picture stuff where you map points to a moving image so you could make like one of thos pictures in Harry Potter where it's in a frame but it's moving, and the frame is tilted at an angle, not straight on.

After Effects is great, you can do alot in it, but if you don't have a lot of RAM it will take forever to render things.

If you watch my latest video of "the Internet is for porn" there are 2 shot there that I couldn't have done without After effects both are Obi wan looking at screens, one is a still image put into the video, the other is video of Oola dancing from Return of the Jedi on his screen.
