Conigs Mixtape
Conigs Mixtape is a collection of presets for Adobe After Effects. Each one was born out of a need from a project I’ve worked on and assembled with custom controls. Buy now and get updates and additions for free.

Key Cloner

Key Cloner is a script panel which lets you easily clone and/or reverse selected keyframes across multiple properties or layers in After Effects! No more hoping you can paste multiple keyframes without getting duplicated effects or layers. And on the off-chance it does work, time-reversing those keyframes only to have to retime those keys anyway.

Zero Tangents

You’ve done it a million times. You set position keyframes and adjust the handles just right, then set the next keyframe only to have an extra handle pop out, leaving you to eyeball the handle to get a straight line. With Zero Tangents, a single click will set the in, out, or both tangent handles to 0 for the selected position keyframes. It’s both a ScriptUI panel and a KBar script that will make you and your keyframes happy.

Release Colors

Get more control over your color keyframes by releasing to individual Hue, Saturation, Luminance or Red, Green, Blue controls. Just select your color properties and either hit the HSL or RGB buttons, or run with no cluttering UI from the Script menu, ft-Toolbar, or KBar.

Wayfinder
Wayfinder is a script for After Effects which allows you to attach and guide artwork along shapes layers… even complicated or animated ones! Select your shape layer, press a button, and get nulls attached to the outline of the shape! Each null has controls for position and offset. The main shape layer gains controls for trim and offset.
