Projection Video for 3rd element

I have been assigned to take a video of a busy street in London for our projection element. I will be in London for some of the days so will take some close up, wide and mid shots for video:

I took the video in my local town, Bury St. Edmunds. There were jagged flows of people coming down this particular alleyway, so in post-production, I had to cut them all together so they fitted well. I also coloured the video into black and white, because our video is quite colourful already, it would be a nice contrast.
