Download the After Effects CS5.5 SDK
Macintosh or Windows

The After Effects CS5.5 release 1 Software Development Kit contains headers defining the After Effects APIs, sample projects demonstrating integration features, and the SDK Guide documentation.

Effect plug-ins described in the SDK can not only run in After Effects, but also Adobe Premiere Pro and Adobe Premiere Elements.  AEGP plug-ins can manipulate nearly every element of After Effects projects, preferences, trigger internal commands, and call scripts.  EMP plug-ins can output video to video hardware.

What's new

Support for two new parameter types has been added: PF_Param_BUTTON and PF_Param_POINT_3D.

We’ve made a few changes to support timecode more thoroughly. PF_AdvTimeSuite has been revised to provide more time information via PF_GetTimeDisplayPref. A new outflag has been added for effects whose render results depend on timecode: PF_OutFlag2_I_USE_COMP_TIMECODE. AEGP Proj Suite is now at version 6, and adds support for getting and setting more time display attributes.

AEGP Comp Suite is now at version 8, and adds support for creating new text box layers. AEGP Render Options Suite is now at version 4, and provides support for getting and setting render quality.

Since we have added new camera and light parameter streams, we’ve added the ability to manipulate those layer streams.

See the section What's New in CS5.5, in chapter 1 of the After_Effects_SDK_Guide.pdf, for further information.
