Animation data are stored in the model. All data related to movements, cameras and visual effects refer to objects of the model via a unique ID. The .animator file is simply a backup file, in case something is corrupted in the model. The fromat is a serialization of the working data structures in the plugin. So, not really designed for a clean export. Exporting the animation would first require that you are able to export the container objects (Groups, ComponentInstance), with their transformations.

@dykassist No, I thought you were asking because your device was not capable. Writing 100s of images does take time so run it while you're cutting the grass. Or if you've a friend/colleague with more grunt ask them to do it and still go cut the grass.
