hey bud, for camera info only just make sure the camera name says camera e.g. camera1 AE will understand this. To bake the camera its under edit>keys>bake simulation
if you need to add video to your 3D elements in AE just add a locator in Maya in the top corner of of where you want to add video in AE. just make sure that the locators are renamed to null. Save file as a *.ma
everything should be good.
