Oscillation Made Easy in AE with Andy Ford

Oscillation Made Easy in AE

An easy way to make items oscillate is to use the Sine expression. Sine is probably something you forgot about from a math class long ago, but using this expression can help you create efficient movements. The Sine expression provides a smoother and more predictable motion then, say, the Wiggle expression.

The expression is written as:

Math.sin()

Your input goes in the parenthesis, and the Sine of that number is the output. For math gurus, the input is thought of as a radian, or a way to measure angles. The output will always be a value between -1 and 1.

In this short video tutorial, we’ll oscillate position using an expression. We’ll create a variable for the frequency and amplitude of the movement. Also, we’ll explore using time as a value.
