Where the term comes from
B-roll is a film and television term. The A-roll is the primary footage: the interview, the presenter, the main action. The B-roll is everything cut in on top of it to cover edits, show what the speaker is describing, or keep the picture moving while the audio continues. The names date back to physical film reels, but the idea survived the move to digital editing.
In a documentary, B-roll might be shots of a city street while someone talks about living there. In a product video, it's the close-up of the bottle, the hands opening the box, the texture being rubbed into skin. The A-roll gives the video its spine. The B-roll gives the editor options.
What B-roll means in a UGC deal
When a brand hires a UGC creator, B-roll is a specific deliverable: short clips of the product that aren't the main talking-head take. Think 5 to 15 second shots of the product on a counter, being unboxed, being applied, being used in daily life, from a few angles and in a few settings. Creators usually shoot these on the same day as the main video.
The brand wants B-roll because a single talking-head clip is a dead end. With B-roll, an editor can cut a new hook, cover a jump cut, build a silent version for feeds with sound off, or splice one creator's demo into another creator's testimonial. The same shoot can produce five or ten ad variations instead of one.
A common brief line reads: "Deliver the main 45 second video plus 8 to 12 B-roll clips: product in hand, product in use, packaging, close-up of texture, and a lifestyle shot with the product visible." That's specific enough for the creator to plan the shoot and specific enough for you to check the delivery.
Raw B-roll vs edited B-roll
Raw B-roll is the untouched clips straight from the phone: full length, no color grading, no captions, original audio. Edited B-roll has been trimmed and graded to match the main video. Most brands with an in-house editor or agency want raw, because they'll re-edit anyway and raw gives them the most flexibility. Brands with no editing capacity often prefer edited so the clips are ready to drop into a template.
Ask for raw as a rule. It's more work to store but it never limits what you can do later. Also ask creators to shoot B-roll in the same lighting and setting as the main video, otherwise the cut looks stitched together. Raw footage as a category usually includes B-roll plus the unedited main takes, and some creators price it as a separate line item.
Why media buyers keep asking for it
Creative testing runs on variations. A media buyer who gets one finished video can test one thing. A media buyer who gets one video plus a folder of B-roll can test different hooks, different lengths, and different first frames without going back to the creator. That turns a single creator deal into a month of testing material.
B-roll also extends the shelf life of a creator relationship. If a hook from six months ago starts to fatigue, the editor can rebuild it with the leftover clips instead of commissioning a new shoot. When you brief a new creator, budget for B-roll from the start rather than adding it after you've seen the main video. It's much cheaper to shoot everything in one session.
How to brief it well
Give a shot list, not a vibe. List the exact clips you want, the rough length of each, the orientation (almost always vertical for paid social), and whether you want original audio. Tell the creator which clips matter most, because they'll shoot those with the most care. If you have a specific hook in mind, ask for a B-roll clip that could open the video without any speech.
Check the delivery against the list before you approve payment. Missing B-roll is one of the most common reasons UGC deliveries go back for revision, and it's almost always because the brief was vague. UGC Agent's brief generator includes a B-roll shot list by default for exactly this reason.
How it's used
Please send the main talking-head video plus 10 raw B-roll clips of the product in use, all vertical, no captions.
The hook died after two weeks but we had enough B-roll from that creator to rebuild it with a new first frame.
