Adobe Aer Eects CS5.5 What’s New
Control light intensity falloff
In the real world, light intensity diminishes naturally the further lit objects are from the light source.
After Effects now gives you the controls you need to simulate natural illumination falloff in a 3D
scene—or create other light intensity effects, if so desired.
Choose the Inverse Square Clamped falloff
setting to recreate the real-world decay of
light over distance, in which light intensity
naturally falls off by the square of the
inverse distance. The Smooth falloff
setting allows you to define the exact
distance over which light levels decay.
With either setting, you can determine at
what distance (in pixels) light falloff starts
and ends.
The same four basic choices of light type
previously offered in After Effects—
Parallel, Spot, Point, and Ambient—all
remain, with each type (except Ambient, which is equal at all positions and thus does not decay)
supporting both types of falloff. You can mix light types, intensities, and shadow casting settings
the same way you could in previous releases of After Effects.
Work with more high-definition source formats
As new formats for gathering high definition footage arise, After Effects continues to add support
for the most versatile and widely used among them, including native R3D support. The RED
ROCKET card for Mac OS and Windows delivers real-time 4K RGB playback and transcoding of R3D
files from the RED camera, and After Effects can import those files directly, reducing steps between
shooting and post-production.
RED RMD files are sidecar files alongside the R3D file that contain information about how the shot
is graded in software such as REDCINE-X. After Effects imports and applies these RMD settings on
import, so that important decisions about how to interpret the color of the shot are not left behind.

Inverse-square lighting falls o naturally, displaying
characteristics of real-world light.
Digital footage is oen shot at low
contrast, resulting in a color range that
diers from the intended nal look. Not
only does Aer Eects include a full
suite of RED tools and seings to adjust
raw source on import, it also supports
sidecar RMD les that contain these
seings from other applications.
