The De-compose plug-in is now available as a 64-bit plug-in for After Effects CS5. The download now comes with both of the 64-bit plug-ins for Windows and Mac as well as the 32-bit versions for those of you who don't have CS5 yet. Simply copy the plugin folder into your plug-ins directory and the option will show up at the bottom of the 'Layer' menu.
The only change in this version of De-compose is that now, the name prefix text box defaults to blank, since most users will not need to know where the layers came from after the composittion has been de-composed.
You can download the plug-in from the After Effects Extras page.
