What is a .aet file?
An AET file is a project file created by Adobe After Effects, a powerful software for creating motion graphics and visual effects. It doesn't contain the actual video or audio data itself, but rather a set of instructions detailing how to combine various assets. These instructions include layers, effects, animations, masks, and timing information, all orchestrated to produce the final rendered video. Think of it as a recipe that After Effects uses to bake your visual masterpiece. It's the blueprint for complex video compositions.

Technical Details
AET files are proprietary binary formats specific to Adobe After Effects. They store metadata, project settings, and references to linked media files. While they can be complex, they are essentially a structured data file that After Effects interprets to render a video composition. The internal structure is not designed for direct human editing or interpretation without the After Effects software.
