Instead of creating a bunch of keyframes to make a layer randomly move, we can do this with a couple of numbers. Wiggle is one of the most popular After Effects expressions, as it is easy to use and visually interesting. If you’ve ever seen animations where light is flickering or a camera shakes, it’s likely you’ve seen the wiggle expression in action. When you understand them they really aren’t scary and can end up saying you a lot of time. In this post we’ll show you how to create wiggle easily by modifying numbers…not keyframes.Įditors sometime cringe at the word expressions, but have no fear. Var max_y = Math.Use an expression to create random movement with the wiggle expression in After Effects. It works only if offset X and Y values are equal (ex.

This expression is one of the many i applied without any success. I tried everything, but I can't get it to work: the extended point doesn't stick with the right proportion over the animation. Is there a way to extend a pin point (example: top left corner point) with different offset values for X and Y using expressions?

Suppose you have a keyframed corner pin effect. I do realize that I'll also have to write an expression to scale the Alpha Matte in relation to the width of the text layer (which should be similar to my first expression at the top), but that's nothing I can't handle.

The keyframes are eased and velocity adjusted as below. The shape layer in question has key-framed animation on both the x-scale, and the x-position. My goal is to make this as user-friendly as possible, so even an 'After Effects Novice' can edit and export! I want the right half of the square to automatically animate further away based on the width of the text layer. A square rolls in then splits in two to reveal text. If I want to link a key-framed 'end position' of a shape layer to the width of a text layer, how would I go about that? Below is a video of my current animation.

I also have a position expression linked to the size.Ĭontent('Rectangle 1').content('Rectangle Path 1').size/2 X=s.sourceRectAtTime(time-s.inPoint,true).width I have had success with linking the width of a shape layer to the width of a text layer using the following expression: I am making a series of fully-customizable lower-thirds, that automatically scale / change based on the width of any given text layer. It may have been renamed,moved,deleted,or the name may have been mistyped. Property or method named '0' in class 'array' is missing or does not exist.
