ADOBE AFTER EFFECTS 5.0
User Guide
Automate the creation of motion and effects by writing custom scripts with the Motion
Math tool—or run the Motion Math scripts included with After Effects. You can even
simulate the accelerating effect of a zoom lens using the Exponential Scale tool, which
converts linear scaling of a layer to exponential scaling.
Audio effects
The Production Bundle expands the range of high-quality audio effects you can incor-
porate into a composition. Add depth and character to a sound with Flange, or make one
voice or instrument sound like many with Chorus. Apply Parametric EQ to isolate and fine-
tune specific ranges of sound. With Reverb, simulate a spacious, acoustically live interior.
Create simple tonal sounds (such as a doorbell) by applying Tone, or use Modulator to
precisely control audio delay and modulation, creating echo and chorus effects. You can
also enhance sounds by removing high and low frequencies with the High-Low Pass filter.
3D Channel effects
Use the 3D Channel effects to create effects with the auxiliary channel information stored
in imported 3D files, including RLA, Softimage PIC/ZPIC, and ElectricImage EI/EIZ files.
Use the Depth Matte effect to read the z-depth information in a 3D file, and then slice the
image along the z-axis to insert other objects. The Depth of Field Blur effect simulates a
camera that focuses on one area in a 3D scene while allowing other areas to blur. The ID
Matte isolates objects in a 3D scene for editing. The 3D Fog effect applies a fog effect along
the z-axis, so that distant parts of a 3D scene look hazier or even disappear. The 3D
Channel Extract effect makes auxiliary channels visible as either grayscale or multichannel
color images, which you can use as image maps or in other specialized effects.
The 3D fog effect applies a fog effect along the z-axis of the 3D file.
