Join Angie Taylor for an in-depth discussion in this video Using Sine and Cosine to make undulating waves, part of After Effects Expressions for Premiere Pro Editors.
- In this section of my movie here,…I want to create a nice waveform animation…of the text and of these little dots to create a pattern…that echoes the patterns seen in this footage.…Now, it can be fairly easy to create…a waveform animation using key frames,…but when it comes to creating multiple items…and you want those items to match up nicely,…it's much easier to use an expression,…and the expression that we use to create…those waveforms are called sine and cosine.…
Now, sine and cosine are two math functions,…but don't be afraid.…And they're normally used in the measurement…of the angle of triangles,…but in After Effects expressions,…sine and cosine are used within the math functions…or math objects in the Expression language menu.…And it's really easy to use them.…You can just drag and drop them onto your properties…to make your properties animate with a waveform.…So, let's have a look at this section here.…At the moment, the text isn't moving at all.…So, we're going to select it and we're going…to hit command D to jump to After Effects.…
After Effects Expressions for Premiere Pro Editors is a creative, project-based workshop. Editors take a basic Premiere Pro edit and bring it to life using After Effects expressions and Dynamic Link, following author Angie Taylor's expert instructions. The concepts are broken down into manageable 3–5 minute videos, covering techniques such as randomizing effects, linking animation and color to sound, automating animation, and more.
