Editing to the beat

At the start of the song there are 4 loud drum repetitions, as this is a narrative video, we decided that that would be a good place to put some editing to the beat . So one lunch time I took the Nikon DX camera and looked for some nice shots we could put at the start, without leaving the school, this is what I came up with. I uploaded them into imovie and put them in time, my group then came and made any necessary changes
