Wiggle, Wiggle
I love using the Wiggle Expression and use it in pretty much every project I create in After Effects; but for a silly side project we did here at And Now Media I had a really hard time figuring out how to wiggle on only one parameter (X or Y, but not both). I’m sure other designers have had this similar roadblock, so we decided to open our tutorial series with that: how to recreate the vertical wiggle of old film using a one parameter wiggle expression with the slider control!



This After Effects Tutorial covers: 1. Basic Wiggle Expression 2. Wiggle Expression in ONE parameter (x or y) 3. Expression, and the Slider Control

Here’s the code for these expressions:

1. Basic Wiggle Expression:

Wiggle(4,20)

The first number in the parenthesis represents TIME The second number represents the Number of Pixel VARIATION

Wiggle( T, V )

2. Wiggle One Parameter (in this case, the Y): The way I prefer to write it:

[ value [0], wiggle(4,20) [1] ]

Same expression another way:

w=wiggle(4,20);
[ value [0], w [1] ]

A third way:

v=value;
w=wiggle(4,20);
[ v [0], w [1] ]

All the information on how this code works is covered in the tutorial.
