B-roll is an essential part of video production that provides visual depth, aids storytelling, and maintains viewer engagement. From cinematic landscape shots and product close-ups to behind-the-scenes footage, B-roll helps make basic footage into a polished viewing experience. So, whether you're making a documentary, vlog, product advertisement, or social media video, knowing B-roll can make your content better. In this guide, we'll go over what is B-roll footage, the different types of B-roll, provide some real-world examples, and discuss how to create cinematic B-roll videos using Dreamina AI Canvas.
What is B-roll footage in films?
B-roll is supplemental footage that complements the primary footage (known as A-roll) to provide context, demonstrate concepts, and make a video more visually interesting. Speaking of what is B-roll in films, these visuals can contain establishing shots, close-ups, environmental detail, and action.
For example, if a filmmaker is interviewing a chef, B-roll might involve shots of ingredients being chopped, food sizzling in a pan, and dishes being served. These shots supplement the primary footage, enhance continuity, and help the audience comprehend the story better.
The importance of B-roll in video production
Now that you know what is B-roll video, let's check out its importance and why these visuals are widely used by content makers to grow their engagement.
- Makes videos more engaging
B-roll gives visual variety with different perspectives, movement, textures, and environments. A fitness video might, for example, cut between a trainer describing an exercise and close-ups of proper form, gym equipment, and workout movements. This change helps keep the viewers interested and makes the content more dynamic.
- Improves storytelling
B-roll allows creators to visually narrate their ideas instead of just verbally explaining them. Supporting footage can amplify emotions, demonstrate actions, and offer information that helps a story flow.
- Covers cuts and editing mistakes
Creators typically cut out pauses, repeated words, errors, or unneeded areas of the main footage during editing. These edits can create obvious jumps in an interview or talking-head video. Placing relevant B-roll over these transitions helps hide visual discontinuities while letting the original dialogue or narration continue.
- Adds context and visual variety
Extra footage can add details not visible in the main shot, giving viewers a more complete picture of the subject. For example, a product review might show close-ups of the buttons, materials, packaging, and the product in use. These extra visuals are good context and also give the video a sense of completeness and visual balance.
What are the different types of B-rolls
- 1
- Establishing shots
Establishing shots set up the setting of a scene and allow viewers to know where the action is taking place. They are often wide-angle or aerial shots of cities, buildings, landscapes, streets, offices, or venues for events. These shots set up the location, create the mood, and prepare the audience for the action that will follow.
- 2
- Cutaway shots
Cutaway shots take the viewer's focus off the main subject for a moment to reveal a connected object, person, action or detail of the surroundings. They're commonly used in interviews, documentaries, tutorials, and vlogs to emphasise what the speaker is talking about. You can show an entrepreneur talking about a product video with sketches, packaging samples, and a team working on a prototype.
- 3
- Insert shots
Insert Shots focus on a specific object, action, or detail that needs closer attention. They are different from wide establishing shots in that they generally focus on a small detail of the scene. For example, in a cooking video, an insert shot may show the seasoning being sprinkled over the dish or a knife cutting through fresh vegetables. These shots help in delivering information clearly, making demonstrations easier to follow and drawing attention to details that might be missed otherwise.
- 4
- Action shots
Action shots show movement and activities that add to the main storyline. It could be a person running on a beach, a barista making coffee, a designer drawing an illustration, or a traveller walking through a crowded market. These clips are high-energy and give the viewer a sense of how a person, product, or environment performs in real-world scenarios.
- 5
- Stock footage and archival clips
Stock footage is pre-existing video footage that creators can license or use under the relevant terms. Archival clips are existing recordings stored for historical, documentary, or reference purposes. Both types can save production time when original filming is difficult, expensive, or unnecessary.
Common B-roll examples to understand
- Scenic landscapes and landmark shots
Establish a location and give a sense of scale with wide shots of mountains, beaches, forests, city skylines, monuments, and other famous sights. For a travel vlog, you could have aerial shots of a city mixed with street-level shots of architecture and local life. You can work with golden-hour lighting, changing weather, and slow camera moves to create a mood, and a cinematic look.
- Lifestyle shots showing the product in use
Lifestyle B-roll showcases how a product fits into everyday life rather than just showing it on a flat background. Examples are a person applying skin care products, a smartwatch during a workout, a coffee machine making coffee, or a laptop in a modern workspace. Demonstrate the product in a real-life scenario. This helps the audience visualise how it can help them and picture themselves using it.
- Relevant visuals that support the interview topic
Additional footage can help to visually support the information provided by an interviewee and to make abstract ideas easier to understand. For example, an interview about living healthy might include shots of people preparing food, exercising outside, and shopping for groceries. These visuals reinforce the speaker's message and also keep long interviews from becoming visually repetitive.
- Close-ups of daily activities and travel destinations
Close-up B-roll can capture small details to help make a video feel vivid and immersive. For example, hands pouring coffee, steam rising from a hot meal, a traveller opening a map, raindrops on a window, or a local artisan crafting an object. These details can convey texture, movement, atmosphere, and emotion without the use of dialogue.
- Behind-the-scenes clips
Behind-the-scenes clips show the process of making a finished product, performance, event, or creative project. It can portray a filmmaker setting up a camera, a team arranging product displays, a designer working on a project, or a creator getting equipment ready before a shoot. This type of footage can humanise a brand or creator by providing a look at the work and decisions that go into the finished product.

FAQs about what is B-roll
How long should a B-roll clip be?
The ideal length of a B-roll clip depends on the video's format, pacing, and purpose. Short-form videos, such as Instagram Reels and TikTok videos, often use clips lasting around two to five seconds to maintain a quick rhythm and hold viewers' attention. Longer formats, including documentaries, interviews, and cinematic travel videos, may benefit from shots that remain on screen for several more seconds. When making B-rolls with Dreamina, you can either choose standard video duration, up to 30 seconds or go for ultra-long video generation for up to 180 seconds.
Can AI generate B-roll footage from text or images?
Yes, many AI video generation tools can create additional footage using text prompts and reference images. You can describe the subject, setting, lighting, camera movement, and mood with a text prompt, and an image reference can help guide the composition or visual directions of the generated scene. Dreamina's AI-assisted video generation workflow unlocks new possibilities for creators to explore B-roll ideas for product showcases, travel videos, tutorials, advertisements, and social media content. You might have a slow cinematic shot of a skincare bottle on a sunlit bathroom counter, or use an image-to-video feature to guide the look of a product scene.
What is the difference between A-roll and B-roll?
A-roll is the primary footage that carries a video's main message, such as an interview or presenter speaking to the camera. Speaking of what is B-roll, it is supplementary footage that adds context and visual variety, such as product close-ups, scenic shots, or behind-the-scenes clips. For example, in a cooking tutorial, A-roll shows the chef explaining a recipe, while B-roll captures ingredients being chopped and food being prepared. With Dreamina, you can generate AI-assisted B-roll clips to complement your main footage and create a more engaging video.
