right now the keyframing is quite basic but very easy to use.
unfortunately, it needs some more tools like curves editing, but to be honest, you can do very good camera movements with some work and the animation module permit to move pretty much everything from the sun to the PF you use, the colours, the objects size, etc...
honestly, i hesitate a long time to buy the anim module (because of the render time problem) but I don't regret it. it is really something to be able to "travel" in your landscape ^^
