Export: Adobe After Effects (.jsx) is a Blender add-on that moves scene data into Adobe After Effects. It exports animated cameras, lights, images, other object locations and tracking markers, writing them to an ExtendScript (.jsx) file.
Once enabled from the Extensions section of Blender's preferences, the exporter appears in the File menu under Export, Adobe After Effects (.jsx). You choose a file name and options, then run the export. An exporter can also be set up from the collection properties. The generated .jsx file loads into After Effects through the Scripts, Run Script File command, which prompts for a composition name and builds it with the cameras and objects in place.
Originally written by Bartek Skorupa with contributions from several developers, the add-on is now maintained by Les Fées Spéciales. It carries a 5.0 rating across 15 reviews and is distributed under the GNU General Public License v2.0 or later.
