This script creates one new layer for each selected layer in the active comp. Each layer contains an arrow that gives velocity feedback.

Having a bunch of layers all distributed in z space. Now the first layer starts to move towards the camera.

This script moves/nudges all Transform keyframes in all layers in all comps to the nearest exact frame for any framerate.

So, where exactly is the secret menu? It is right in front of you, in the main Radio Waves Effects Panel, but it is hidden in the form of Frequency, Opacity, Fade-in and Fade-outs.

A simple trick for animating clouds in a realistic fashion, without creating masks.

A practical application of a layer space transform.
Not very new, but still very useful.

Interactively control camera focus distance.
The camera will focus wherever your null or solid happens to sit. This expression is golden when you're doing a lot of Depth of Field work.

A Macro that allows you to set objects at Z distances and creates a camera that pans, dollys, cranes etc keeping parallax. Also calculates the relative focus for each layer including using hyperfocal which can be turned on or off.
