What is a .AEP file?
AEP is Adobe After Effects’ native project file, holding the compositions, layers, effects and references to the footage used in a motion-graphics or VFX project. Created and opened by Adobe After Effects.
- Did you know
- An AEP is a RIFX (big-endian RIFF) file whose form type is the playful four characters "Egg!".
- After Effects was first built by the Company of Science and Art in Providence, Rhode Island, before Aldus and then Adobe acquired it.
- An AEP file does not store video itself - it records the layers, effects and keyframes that reference your source clips.
- What Analyser shows you
- Open Adobe After Effects projects (.aep) and templates (.aet) in the browser. Analyser walks the RIFX chunk tree to rebuild every composition timeline - each layer drawn as a bar positioned by its in and out point, colour-coded by footage, pre-comp, audio and shape, with 3D layers marked - and reads each comp's dimensions, frame rate, duration and layer count. The After Effects version that created and last saved the project (and the create/modify dates) are read from the embedded XMP metadata, alongside the list of footage and source files the project references.
- Open a .AEP file
- Drag a .AEP file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
