LayerMonkey is a versatile script for After Effects that arranges and animates your comp’s layers in time and space. It also creates a parented camera and generates a master control layer that makes timing and global adjustments a piece of cake. Now stills, videos and pre-comps can be used as kinetic elements in a complex monkey-generated composition with a simple push of a button

• Creates randomized complex kinetic layouts using layers in your comp based on parameters entered into the control panel.
• Features 3 different algorithms with a Justify option.
• Works with stills, video, pre-comps, shapes, solids, text, eps and pretty much any other type of layer AE accepts.
• Multiple controls for handling time-based layers.
• Variable layer order options.
• Keyframe-less timeline makes changes to timing as simple as sliding a marker.
• Creates a parented camera that points to each successive layer as it transitions on.
• Distributes markers across the timeline in 3 different ways.
• Exludes non- image based layers in comp such as nulls, cameras, audio and adjustments.
• Manual adjustments are easily made to size, position, rotation and opacity.
• Features a wide range of type transitions randomly selected by default, but can be specified as well.
• Marker Sync feature allows for push button alignment with preexisting marker layers, making syncing to music a breeze.
• Allows for different interpolation for camera movement, auto rotate and auto frame.
• Automatically builds and cleans to facilitate easy experimentation.
• Palette controls makes colorizing layers very easy.
• Kuler color palettes are now easily imported.
• Supports motion blur, lock & shy, and preset Load and Save.
