Animated singalong lyrics for Music Video
 

I'm working on a project, and wonder if anyone knows how to do this.

I've seen some singalong lyrics before, like on music videos or kid's movies, where there's like a bouncing ball or something over the word being sung, and the word is highlighted.

I could probably do this in final cut pro, but I'm wondering if there is a generic plugin or something that would be better at this and streamline the process. Is this something that Apple Motion would be good for? I have Apple Motion but I am on a G4 so I can't use it at the moment and don't really know the capabilities.

Any ideas?
