Debugging expressions. 31 Essential Scripts from AEScripts.com. If you have never used scripts before, you are missing out.
These extensions to your After Effects arsenal can be invaluable. There are tons to choose from, they do a wide range of tasks, and new ones are being developed all the time. Lloyd Alvarez, our former editor actually runs AEscripts.com, an online marketplace and central hub for everything scripts in the AE Universe. This is quite the script to start this roundup off with. For those of you that haven't heard of BG Renderer, it renders your videos and everything in your Render Queue, in the background... pretty straightforward.
Quite possibly my favorite script, and not just because of the mustache, is Magnum - The Edit Detector, which can scene detect any piece of footage you throw at it. After Effects ExtendScript Training Complete Series by David Torno. After Effects ExtendScript Training is a video training series on Adobe® ExtendScript for After Effects®.
This script connects the selected layers with segments or triangles created with shape layers.
It was originally created to visualize Newton2 joints but as you will see, it can do much more. Rope Creates a single shape layer with a path connecting the selected layers (2D only). Use AutoBezier or Tension options to get rounded joint style. Spanning Tree Computes minimum spanning tree and draws each edge with a shape layer (2D and 3D support). Triangulation Triangulates the selected layers and draws each edge with a shape layer (2D and 3D support).
Note that for functions that create shape keyframes (Triangulation with Filled Triangles turned on, and Rope), keyframing is done within the comp work area. Quick start guide Compatibility: For AE CS6 or later Current version: 1.08 – Initial release – May 2013. Expressions - Geometry. AE Tips and Tricks.
Expression language reference. Return type: Number or Array.
Argument type: freq, amp, octaves, amp_mult, and t are Numbers. Randomly shakes (wiggles) the value of the property. freq value is the frequency in wiggles per second. amp value is the amplitude in units of the property to which it is applied. octaves is the number of octaves of noise to add together. Amp_mult is the amount that amp is multiplied by for each octave.
T is the base start time. Example: position.wiggle(5, 20, 3, .5) produces about 5 wiggles per second with an average size of about 20 pixels. This example, on a two-dimensional property such as Scale, wiggles both dimensions by the same amount: v = wiggle(5, 10); [v, v] This example, on a two-dimensional property, wiggles only along the y axis: freq = 3; amp = 50; w = wiggle(freq,amp); [value,w]; Paul Tuersley provides a script on the AE Enhancers forum that automatically adds wiggle, smooth, and loop expressions to selected properties. Scripts & Plugins. Dan Ebbert. After Effects Expressions. I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language.
That’s cool with me. Therefore, I’d like to share with you my top 5 after effects expressions. These are expressions I use in just about every project, and I consider them to be incredible workflow enhancements. Expressions. From 1.
Intertial Bounce Essentially, Inertial Bounce creates a bouncing motion of any parameter from one keyframe to the next, based on its velocity. Being that true “velocity” includes the vector (or traveling direction in 3D space), the bounce happens in whatever direction the object is traveling. This also accounts for scalar or array values, so you’ll find that this expression works just as well on 2D rotation as it does on 3D position. Java.
