VIRAL VIDEO: Timelapse video captures beauty of San Francisco

(KGO) -- A new video shows the city of San Francisco like you've never seen it before.

Videographer Marc Donahue spent a year shooting timelaspe footage of some of the city's most stunning locations and views and then edited together to a cover of the Tony Bennett classic, 'I left my heart in San Francisco.'

Donahue says that song in part inspired him to make the video.
