One second of architectural animation has from 25 to 30 frames. On the average, every frame is rendered through 40 min. (trivia: for the film “Horrible University” the time of the rendering took 29 hours per frame). One minute of the animation requires the constant rendering for 41 days on the home computer. Fortunately it is possible to shorten the time and cut costs using game engines e.g. Unreal Engine 4, however with cost of the quality and the greater workload.
