A-Roll / B-Roll
also: A-roll · B-roll
-roll is the primary story-bearing footage, typically interviews, principal action, or the main scene coverage. B-roll is supplementary material—details, environments, process shots, reactions, inserts—that adds context, hides edits, and enriches rhythm and meaning around the primary material. In documentary, A-roll typically consists of the primary interviews ('talking heads'), while B-roll encompasses all other visual material—archival footage, re-enactments, vérité scenes, and illustrative shots—used to cover edits in the A-roll and visually express the concepts being discussed. In modern documentary and content creation, the process of selecting B-roll can be initiated by analyzing the A-roll transcript to generate a shot list of necessary visual concepts, a task that can be assisted by AI. Workflows like 'paper editing' are designed to first build a strong narrative backbone purely from the A-roll (interviews, dialogue) via transcripts, before considering how B-roll will be used to cover edits and illustrate concepts.
in short
Primary footage versus supporting contextual footage.
usage
Used in documentary, branded content, journalism, and reality/editorial planning to organize what carries the core narrative versus what supports it.
notes
The distinction between A-roll and B-roll is particularly critical in workflows like transcript-based editing, where the A-roll (dialogue) is edited first via its text transcript, creating the structural and narrative spine of the piece. The B-roll is then layered on top to cover edits and add visual context.
