exporting camera path

I’m gearing up to do an animation with mixed elements between blender and after effects. Does anyone know how to get camera info out of blender and in to after effects? or vice versa

ok so to get camera data into after effects what i really need is a .rpf file
can blender export rpf files? is there another format that I could export from blender, open in 3ds and then expoprt a .rpf?
