- Be sure to bake keyframes on anything animated. (the camera, the locators) (Edit > Keys > Bake Simulation) The curves don't line up otherwise and things will drift.
- Make sure to name your locators so their names start with "null" instead of "locator" or they won't import
- You need to bake the same range of keys for everything you bake or you'll get an error on import.
- Save as Maya Ascii -- usually best to just select your camera and locators you want and do Export Selection.
By default, the units in AE will match the Maya units you're using. So if the camera is at [10, 15, 0] in Maya, it'll be at the same in AE. You need to move things to 0,0,0 in AE to be at the center of the scene. This also makes for a very small scene scale in AE so you can have to scale things down to, like 2% to get them to be the right size in AE. Solution is to scale your scene up in AE: Make a Null in AE, make it 3D, put it at 0,0,0, parent the camera and nulls you've imported to this null, scale the null up 1000% (or more or less, depends), then unparent.
Sometimes things won't match up if you're using some expressions or funky parenting to modify the animation. If a locator isn't matching, it usually works to create another one, point and orient constrain your new locator to the original, and then bake keyframes on the constrained one. Delete the constraints and then export that. I've had to do this on cameras as well when I've used a MEL script to add some camera shake.
It's not as easy as Cinema, but it works. Are you having any particular problems?
Hope that's helpful,

hey all,
I'm working on a shot where I'll need to integrate a maya camera and
locators into my AE comp and am wondering if you can offer any
pointers or gotchas I should look out for. I've heard from some people
that were never able to get the resulting AE camera to match the Maya
camera perfectly and locators didn't translate correctly either. What
I'd like to do is import the maya camera and several locators that
will be parented to several characters finger tips. Any insight that's
not in the official documentation is appreciated. Thanks!
