Join Chris Meyer for an in-depth discussion in this video Idea corners 1: Manic blur, part of After Effects Apprentice 09: Expressions.
We are going to end this introductory lesson on expressions with a few more ideas of…what you can do with the Wiggle expression.…I'll be in the Idea Corner folder, and first let's open up the movie Idea1-Nervous Text.mov.…I will play through this, and you see we have some text that is randomly going…in and out of the focus.…Rather than requiring a lot of keyframing, this is a trick that just required a…relatively simple Wiggle expression.…I will open up the comp Idea1-Nervous Text,…select the text layer Interference, type EE to reveal all the expressions, and…type Shift+E to also show all effects applied to this layer.…
To create this blurred look, I used the Directional Blur effect.…I'll press F3 to open up the Effects Control panel. And it contains just two…parameters: Directional Blur and the Blur Length.…Down here in this Timeline panel, I applied the Wiggle expression to both…of those parameters.…But instead of just typing in numbers, I also created a series of Expression…controls to give me a user interface on the amount of this blur.…
