B-roll is the extra footage captured to enrich the story you're telling and to have greater flexibility when editing. Instead of featuring only talking heads on video, you want to have other images you can cut away to that will add dimension to your story. The term “B-roll” comes from the world of film where editors used to use an “A” and a “B” roll of identical footage, before the digital age changed everything. It is alternative footage intercut with the main shot. B-roll shots are similar to cutaways in that they help break up the shots of the artist rapping in the music video.It can make telling your story much easier and compelling with added footage. As a general rule B-Roll can include animation, graphical elements, photographs and extra footage.
