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. Tutorial with multiple examples of wiggle expressions in After Effects from wiggle text to camera shake, also providing free After effects project source files so you can see how wiggle expressions are integrated with the layers. 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(). Math It would be handy to directly set min and max values, but have the normal controls over wiggle (freq,amp,octave,seed).
PosterizeTime() is a powerful, but simple, expression that will return a value every X number of frames. Traditionally, if I want to wiggle between 5075, I’d set the starting value at the midpoint (75-50)÷2+50 then set the amp value to (75-50)÷2. 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. Create a new solid (Layer > New > Solid), make the dimensions small, choose black as the color, and click OK. Starting in the Standard workspace, import your footage and place it in a new composition. How to Create a Stop Motion Effect to with posterizeTime() and a Wiggle Expression This project uses Noise, Transform, and Wave Warp effects as well as some wiggle expressions in After Effects.
