Getting Started With Explainer Videos After Effects
This goes through how to get organized and get started with animations for explainer videos created with After Effects. A great way to keep the motion happening is to use a script to softly make visual elements breathe. Here is is done with an expression and alternatively with a controller to give you global control over all your layers of animation.
w=wiggle(10,40);
[w[0],w[0]]
speed=thisComp.layer("control").effect("speed")("Slider");
amount=thisComp.layer("control").effect("amount")("Slider");
w=wiggle(speed,amount);
[w[0],w[0]]
