Research - BBC advert

I was watching tv and I saw this advert, and noticed it was a Calvin Harris song. People sent in home made videos of themselves dancing, singing, creating sounds to the song 'Bounce'. Then it was edited so it all comes together in one big collaboration. It becomes a video montage/collage and the clips are edited into lots of shapes. There is also cameos from artists and celebrities such as One Direction and Cher Lloyd.
