## Definition

B-roll is supplementary footage used to visually support the main narrative of a video, providing visual variety while voiceover or dialogue continues over the cut.

## Extended Definition

B-roll is a filmmaking term for secondary footage intercut with the primary shot (A-roll). In content creation, B-roll serves several purposes: illustrating concepts being discussed, maintaining visual interest during talking-head segments, covering jump cuts, and adding production value. Traditional B-roll requires separate filming or stock footage licensing. AI-generated B-roll automates this process by generating relevant visuals from the script or voiceover context. BlitzReels' automatic B-roll feature analyzes the script, identifies scenes that benefit from visual support, and generates or sources matching footage. This dramatically reduces the production effort for educational, explainer, and faceless video content.
