The 12.5-minute movie is CG-animated, running a slow visual survey of some iconic buildings, including Louis Kahn's Exeter Library and Tadao Ando's Shiba Ryotaro Memorial Museum. The animation is so pristinely done that the comment section beneath Roman's video has drawn some vehement doubters who simply can't believe it's CGI (followed by equally vehement defenders of the artist's skill). There is a shorter film demonstrating some of the breakdown and process of putting the animation together, which can be found here.
