What is a AEPX file?
An AEPX file is a project file created by Adobe After Effects, a video-editing application. It contains a video composition, which includes references to video assets, motion graphics settings, and visual effects. AEPX files are used for creating professional-quality video productions.
NOTE: Older versions of After Effects use the .AEP extension, which saves projects in a binary format instead of using XML.
