Thanks to all

Pierre, that dolly back zoom in camera setting is one of my favorite "tools" to add dramatic to a scene. (Thanks for the description - I didn't know how it's named but I liked the effect

)
Hannes it's very difficult to say, because especially the forest animations are quite old. I rendered them between 2015 and 2017. And at that time I used maximum AA3-AA4 and very seldom AA5. Meanwhile I use mostly minimum AA6. More and more often AA8 and in some seldom cases AA10, AA12 or above.
The newest renders are the Vree interior shots. They are AA8 and needed per scene appr. 15 days.
But if you want just a number -- all together 5 Years ...
