Thank you for the response, I tried that already but rotation got completely botched, I found the solution in the meantime :

1) Create a new camera and put an Expresso Tag on it.
2) Inside expresso link the global matrix of the previous camera to the new one.
3) In the timeline viewer just bake the new camera.
4) Enjoy and export to FBX if needed.

Leaving this here in case someone else needs it.
