You can import a Photoshop
(PSD) file directly into an After Effects project with the option
of preserving individual layers, layer styles, transparent areas
and layer masks, and adjustment layers (preserving the individual
elements for animation).
Note: After Effects works in RGB
color mode. For best results, work in RGB mode in Photoshop for
files you will be exporting to After Effects. After Effects CS3
can convert files from CMYK to RGB. After Effects 7 and earlier
cannot convert files from CMYK to RGB.
Before you export a
layered Photoshop file for use in After Effects, do the following
to reduce preview and rendering time and to avoid problems with importing
and updating Photoshop layers.
