Definition
B-roll is supplementary footage intercut with A-roll to illustrate a point, cover an edit, establish a location, or create mood and visual rhythm. Typical examples include establishing shots, cutaways, inserts, process shots, screen recordings, archive material, and stock footage. B-roll is an editorial role, not a quality ranking or a camera assignment: a B-camera can supply primary interview coverage or supporting footage. The same shot can function as A-roll in one edit and B-roll in another. It can play under the main dialogue or carry its own natural sound. Whether footage is evidence of a particular event depends on its provenance and context, not on calling it B-roll.
How Loopdesk Uses This
For B-roll in a Loopdesk edit, describe the supporting shot and where it should appear, then confirm the current generation and placement tools. Review each insert for relevance, timing, and provenance rather than assuming suggestions are automatically appropriate. Generated or unrelated stock images may illustrate a topic, but they are not evidence that a specific unrecorded event occurred.
Cover the cut without a stock-footage rabbit hole
Refine the main dialogue edit, then explore Loopdesk's current tools for adding supporting footage. Review placement, timing, and provenance before final picture lock.

What is B-roll footage?
B-roll is supplementary footage used to illustrate a point, cover an edit, establish a location, or add atmosphere and visual rhythm. It often appears over continuing dialogue or narration, but it can also carry its own sound.
What is the difference between A-roll and B-roll?
A-roll carries the primary story or action; B-roll supports it through illustration, context, atmosphere, or cutaways. Either can have useful sound, and both can come from any camera. Muting a clip is not a reliable test.
Is B-camera the same as B-roll?
No. A B-camera is a camera assignment, usually the second camera on a shoot. B-roll is a supporting role in the edit. A B-camera can shoot either primary coverage or supporting footage, depending on how the shot is used.
