B-roll footage, sometimes referred to as overlay footage, is supporting video content used to add context and visual interest to a video.

Rather than focusing on a main subject or interview, b-roll captures wider scenes and complementary shots that help illustrate and reinforce the primary footage.

Companies use b-roll to create more engaging video content, adding depth, variety, and a stronger visual narrative.

While interviews and key moments form the foundation of a video, b-roll is what brings the story to life, giving viewers a clearer sense of the environment and keeping them engaged from start to finish.
