Exporting Mp4 from Media Encoder

[mitch@nicksenglishhut.com]

I would like to export a .avi file created in After Effects via Media Encoder as a 1080p Mp4. So far it wont let me do anything but small lo res movies. No joy here. What am i missing?

Hmm that's odd. Personally I don't use .avi files since I'm Mac-based, but I assume the options would still be there. Can you post a screenshot of the options you see in you Media Encoder export window (including presets)? Is Media Encoder changing the output dimensions when you send it over to Media Encoder? Does rendering it out of After Effects give you that option?
