Adjust the frequency (f) and amplitude (a) values to customize your effect.ĭone! Now you can get the randomness of a wiggle expression, but add a lower frame rate - all in one easy expression. Use this expression on position, scale, and rotation properties and watch your layer come to life. In this case, we are using posterizeTime() and the wiggle expression together to create a 'poor man's stop motion' effect. Want to recreate the smooth camera but choppy animation style of Into the Spiderverse? You can get that effect with careful use of posterizeTime(). PosterizeTime() is a powerful, but simple, expression that will return a value every X number of frames. Wiggle (x,y) where x and y are in digits, x stands for the number of times you want the layer to wiggle, and y stands for the number of frames in which you want that layer to move. Here's a simple expression to add to a layer to create a Stop Motion effect with a low FPS (frame per second) and wiggle. Wiggle (camera shake) is one of the most common, easy-to-remember After Effects Expression and is applied to the position property of a layer. You might already be using the Wiggle expression, but are you sure you understand exactly what it's doing In this tutorial I'll walk you through exactly how.
