Why Can’t You Export an MP4 From After Effects?
With the abilities that Adobe After Effects has it seems crazy that you can’t export to MP4 from it doesn’t it?
Well, yes and no.
As a video professional you need to know the ins and outs of video codecs and video wrappers.
MP4 = Video Container
You see, MP4 is a video wrapper delivery format. It is not a video codec. MP4 is commonly associated as a codec because for the majority of people it houses the H.264 video codec and the two become intertwined in people’s minds, incorrectly.
H.264 = Video Codec
But you can have the H.264 video codec in other video wrappers, such as .MOV or .flv. The table below gives you an idea of the difference between video containers, video codecs, audio codecs and metadata:
After Effects is a tool for motion designers and animators to create in but not usually to deliver from. There is usually a need to go to Premiere Pro or Media Encoder to finish your creation in the desired delivery format.
Because After Effects isn’t a delivery tool it doesn’t allow for exporting in delivery formats. Hence the need for Media Encoder.

It’s Still Very Simple to Export via Media Encoder
As you saw in the quick answer at the top, it’s very quick and easy to export to MP4 via Media Encoder.
Note. Be sure not to choose the MPEG-4 preset from the left-hand menu. MPEG-4 is a codec, not a video wrapper and you won’t achieve your desired result using that method.
