Two questions related to camera track in blender

All questions are related to exporting the camera track result out of Blender I tried with Maya and Houdini.

1-When I try to export the camera with the camera solve constraints to FBX I get no camera animation outside blender I am missing something? How can I bake the camera solve constraints and get rid of it?

2-To export alembic and get the empties out of Blender the only way I got to do it is create the empties for each track so far so good but to get their real position I have to click the option “3D position” for each individual constraint is there a way to do it all at once?

Thanks in advance.
