B-roll

B-roll is supplementary footage in video production that plays under narration or dialogue while the main subject speaks or the script advances. It covers establishing shots, archival clips, maps, and detail shots that give the viewer something to watch besides the talking head or the voiceover alone.

Why it matters

A creator who does not understand b-roll makes one predictable mistake: they build an entire video out of primary footage and then have nothing to cut to when the edit needs breathing room. The result is a static frame held for too long, a jump cut where none was needed, or a section of narration with no visual at all. Knowing what b-roll is changes how you plan a shoot or a research pass, because you start collecting coverage before you sit down to edit instead of discovering the gap afterward.

It also matters for sourcing. B-roll carries its own rights questions. A clip pulled from a news broadcast, a government archive, or a stock library has different licensing terms than footage you shot yourself, and a documentary-style channel that ignores this can get a claim or a takedown on a video that took days to produce. Treating b-roll as sourced material, with a record of where each clip came from, is part of treating it as a professional asset rather than filler.

An example

A short-form documentary about a maritime disaster opens with the narrator describing the ship's final voyage. While the voiceover runs, the screen shows archival photographs of the vessel, a chart tracing its route across the ocean, and slow pans over newspaper front pages from the week it sank. None of that footage shows the narrator or the event itself. It exists so the viewer's eyes have somewhere to go while the story is told. The same structure appears in aviation disaster videos, where crash animations and air traffic control transcripts serve as the visual layer under the narration.

Terms people confuse this with

• Cold open: a scene placed before the title or intro to hook the viewer, whereas b-roll is supporting footage used throughout.
• Cutaway: a specific editing technique of briefly leaving the main shot, often using b-roll as the material you cut away to.
• Aspect ratio: the width-to-height shape of the frame, which constrains how b-roll must be cropped, not what b-roll is.

Where this shows up in ViewMade

ViewMade sources real archive footage, maps, and charts for every Short, which functions as the b-roll layer under the narration, and ships a media credits file naming each clip's origin.
