This is the new way timelapses will be done. Well, it will be one day, when people have tens of thousands of dollars to spend on the equipment, and an unlimited time frame to edit it all together. Sadly, I don’t think software will ever be able to do this. Which, I guess means that it’ll forever be that much more impressive for all future videos that are made in this vein.
Kessler University has a whole write up on how it was done, it’s impressive, most impressive.
