This is a music video made by the Emirate of Qatar (a small country in the Arabian Peninsula on the Persian Gulf) made for the closing ceremony of the World Cup (football/soccer), which that small country recently won.
Riding on his horse up an impressive flight of stairs is Qatari prince, Shiekh Mohammed Al Thani, lighting the Olympic torch at the beginning of the games.
Although I can't readily see it, I've been told that themes from "10,001 Nights" and other Arab legends are portrayed in this clip.
Cool to see how the music video form has been adapted to Arab culture here.
