I'm quite fond of the dynamic background in the main menu, and was wondering if I can somehow recreate that with my own playthroughs in a somewhat non-timeconsuming way. Preferably without loosing stuff like spell animations and avoiding inventory and other menus from popping op.
What i want is more or less a way to record the moment i decide what to do untill it's my turn again - but how?

How does the game do it? Is it live AI or does it use some kind of demofile?
tl:dr
Can i produce a movie as similar as possible to the dynamic background in the main menu without recording and manually editing the entire video?
Great game btw!
