Four-year time-lapse of Shanghai Tower being constructed

Filmmaker Joseph Nafis has spent four years creating a time-lapse of the construction of the Shanghai Tower.
He took 350,000 photos from his balcony and sought the help of drone pilots and colourists to make a stunning video.
The tower, which was finished in 2015 after seven years, is the tallest in China and the second tallest in the world, though is yet to open.
