Adobe After Effects can render its projects (.aep) as MPEG-4 files (.mp4). This can be done using the program's default Composition ► Pre-render... function. This function adds visual effects to multimedia files and is likely the only way to convert aep to mp4.
As far as we know, this is the only way to perform this particular app to MP4 conversion, and no third-party app converter exists.
