This tutorial will probably be more than you want, but it gives you a good introduction to using several effects. The one you want to focus on is the displacement map.

Take a look at what Greg posted. Is that what you are looking for?

Greg,
That is a very cool effect. Masks and displacement map, eh? Very nice.

I agree with you Christopher. Radio Waves is difficult to control. It emits a wave at the beginning even if you don’t want it.
Although I haven’t tried it, maybe using a layer with a mask would work. You could control the mask expansion in an expression. You would also need something to continue the expansion after you trigger it.

I must be doing something wrong. I put the expression in the rotation of the arrow, parented the arrow to the earth, and parented the earth to the sun. When I rotate the sun, the arrow doesn’t always point at the sun.

Dan,
Why would you use an expression instead of a null object in this case? Am I missing something?

What you need to realize is that a button is simply an area that can be activated to do a specific action. It doesn’t matter what is on the video.
The button can be invisible. The colors used for the various states that a button can have do not need to be seen. Using the method that Jon Geddes talked about above is probably the easiest way to put a button on a video.
I recommend you watch Andrew Kramer’s tutorial about DVD authoring at Video Copilot. He takes you through using After Effects to create the motion background (including the intro) and the buttons using the method Jon described.

How did you use the write-on effect to reveal the swoosh?

Enter + before – like this: +-10.
