A-Roll
The primary footage that tells the main story, such as interviews or dialogue scenes.
In depth
In documentary filmmaking and news production, A-Roll refers to the main audio and video portion of the story—typically the interview subject talking or the reporter speaking to camera. It drives the narrative forward.
Example
“The interview with the director explaining his vision is the A-Roll.”
Origin and history
The A-Roll/B-Roll distinction emerged from physical film editing in newsrooms during the mid-twentieth century, when editors literally worked with two rolls of film: the 'A' roll carried the primary interview or anchor footage, and the 'B' roll provided cutaways. The terminology survived the transition to videotape and then to non-linear digital editing because the workflow it describes — primary track plus supporting track — remained essential to documentary and journalism storytelling.
Why filmmakers use it
A-Roll is what gives a piece its spine. Without strong A-Roll, no amount of glossy visuals can rescue a story, because A-Roll carries the spoken information and the human voice that audiences anchor to. Editors typically lock A-Roll first, build a clean dialogue or interview spine, and only then layer B-Roll on top. The discipline of separating these tracks is what allows long-form journalism, podcasts, and documentaries to feel coherent rather than scattered.
More examples in cinema
- In a 60 Minutes profile, the sit-down interview with the subject is the A-Roll that the entire segment is structured around.
- A YouTube video essay about a film treats the narrator's voiceover as A-Roll, with movie clips serving as B-Roll commentary.
Common confusion
A-Roll is sometimes confused with a 'master shot' in scripted filmmaking. They are not the same — A-Roll is a documentary/journalism workflow concept, while a master shot is a wide coverage angle in dramatic production.
