B-roll: the footage that makes talking videos watchable

01

A-roll and B-roll

A-roll is the main footage that carries the story, usually someone speaking: an interview, a talk to camera, a testimonial. B-roll is everything else: shots of the product, the workspace, hands at work, customers, the street outside, close-ups of details. The audio from the A-roll keeps playing while the B-roll is shown.

In a well-edited business video, the speaker may be on screen for less than half the time. The rest is B-roll illustrating what they are saying.

02

What B-roll does in the edit

It shows what is being described, so viewers understand faster. It hides cuts: when an editor removes an "umm" or a repeated sentence from the speaker, the jump is covered with B-roll. It changes the rhythm, which keeps attention. And it adds proof: seeing the actual kitchen, factory or clinic is more convincing than hearing about it.

Without B-roll, the editor's only options for removing mistakes are visible jump cuts or leaving the mistakes in.

03

What to film

Think about what the speaker will mention and film it. For a restaurant: ingredients, cooking, plating, the dining room, customers eating. For a manufacturer: machines running, quality checks, packing, dispatch. For a clinic: reception, equipment, consultation rooms, without showing patients without consent. For a service business: the team at work, client meetings, the result.

Add general shots too: the signboard, the entrance, the street, the team walking in. These are useful openings and transitions.

04

Shoot details and movement

Close-ups are the most useful B-roll: hands, tools, textures, steam, labels, screens. They work in both horizontal and vertical edits. Shots with gentle movement, such as a slow push towards a product or a hand placing something down, cut together better than static shots. Hold each shot steady for at least five to ten seconds so the editor has a usable middle section.

Film each shot two ways: wide and close. It doubles your options for almost no extra time.

05

How much is enough

A rough rule: shoot at least as much B-roll as A-roll, and ideally two or three times as much. For a two-minute talking video, fifteen to twenty minutes of varied B-roll gives the editor real choice. Variety matters more than quantity: thirty different shots of eight seconds each are more useful than one shot of four minutes.

Reels and short videos need even more variety per second, because shots change every one or two seconds. A 30-second reel can easily use fifteen to twenty different shots, so shoot generously.

06

Phone B-roll is fine

B-roll does not need a cinema camera. A modern phone shooting in good light, held steady or on a small gimbal, produces perfectly usable B-roll. Keep the frame rate and orientation consistent with the main footage where possible, clean the lens, and avoid digital zoom, which makes footage soft.

Plan B-roll from the script

The easiest way to get the right B-roll is to read the script or interview questions and list every thing, place or action mentioned. That list is your shot list. Anything mentioned but not filmed becomes a gap the editor fills with stock footage or a static shot of the speaker.

If they say it, try to show it.

Shoot B-roll after the interview if you can, when you know exactly what was said. A ten-minute walk around the premises with a phone afterwards often rescues an edit.

What is B-roll in video?

B-roll is supporting footage shown while the main audio plays: shots of products, places, people at work and details. It illustrates what is being said and hides edits in the main footage.

How much B-roll do I need?

At least as much as your main footage, ideally two to three times more. Variety matters most: many different shots of five to ten seconds each.

Can I shoot B-roll on my phone?

Yes. A modern phone in good light, held steady, produces good B-roll. Match orientation and frame rate to your main footage where possible and avoid digital zoom.
