Anyone know how to make animated view frames and shapes in After Effects like what you see in Bleach Technique Beat by Decoy? The best example is probably at 3:12-3:13. It creates a highlighted section of the video by animating lines together until they make shapes, and moving them, and also has a moving target effect like you see in the Ironman movie.
I am using After Effects CS3 and have some ideas of my own that I'd like to bring to life, but I have no clue on how to create them, and I figure this would be a good example as a starting point to learn. Once the technique is figured out I think I should be able to come up with more creative effects.
Also, how is the thin borders colored and animated like that? (In this video it would be black, but I have seen white and yellow before too.)
Anyone know how these effects are created?
