A-Roll vs. B-Roll in Filmmaking: What’s the Difference?
The distinction between A-Roll and B-Roll footage is foundational in video production.
Starting life in the documentary space, each of these have a specific purpose in telling a story, providing context and detail that interweave to create compelling narratives. But now, A-Roll and B-Roll is used in movie and TV production and is just as important as it is in documentary-making.
Let’s take a look at each in turn:
What Is A-Roll?
A-Roll is the core footage that forms the backbone of a video project. It includes the main subjects, dialogue, and actions that convey the primary message or story.
For example, in a documentary, A-Roll would encompass interviews with key individuals or footage of central events. This footage is essential as it delivers the project’s main content.
Similarly, in movies, A-Roll includes the scenes that drive the main narrative, such as character interactions, dialogue-heavy moments, and key action sequences.
A-Roll Examples
- Interviews with subjects discussing their experiences or providing expert opinions.
- Footage of speakers delivering talks or lectures.
- Coverage of the main activities of an event, such as a ceremony or performance
What Is B-Roll?
B-Roll refers to supplementary footage intercut with the main A-Roll footage, providing additional context and cover edits. It also enhances the visual storytelling by illustrating points made in the A-Roll.
In movie making, B-Roll is vital in providing additional context, perhaps with shots that enhance storytelling with visual variety, or smooth transitions between A-Roll scenes.
Examples of B-Roll
- Cutaway shots from the main action to show related visuals, adding depth to the narrative.
- Establishing shots that set the scene, such as exterior shots of a building before moving inside.
- Atmospheric shots that capture the environment or mood, like crowds at an event or scenic landscapes.
- Correcting pacing within a scene, smoothing out any jarring transitions within A-Roll footage.
- Hiding errors made within A-Roll footage. This could be because of a continuity issue, or other mistake during filming.

How A-Roll & B-Roll Work Together in Video Production
The combination of these two types of footage is vital for producing engaging and dynamic videos. So, what’s the difference between A-Roll and B-Roll?
A-Roll delivers the main narrative, while the B-Roll complements it by providing visual context and aiding in transitions. For example, if the A-Roll features an interviewee discussing their artwork, the B-Rol might showcase close-ups of their creations or shots of them working in their studio.
In film editing, A-Roll and B-Roll work in harmony to create a balanced and engaging narrative. This balance allows filmmakers to enhance a scene’s emotional impact, like cutting to a character’s hands trembling (B-Roll) while they deliver an emotional speech (A-Roll), to deepen an audience’s connection.
The combination of both types of footage can also be effective in building atmosphere with B-Roll establishing shots and environmental details providing a strong sense of place and mood before diving into the main A-Roll action.
How are A-Roll and B-Roll Filmed?
Larger documentary and movie productions simply won’t be able to film both A-Roll and B-Roll footage. So, instead, two separate crews will film. These are the first unit and second unit.
First Unit
The largest of the two crews, the first unit’s job is to shoot the A-Roll footage that drives the narrative.
You’ll usually find the production’s main actors and director in this unit, focusing on the overall thread of the story. Of course, if it makes sense logistically in terms of location or scheduling, the first unit will film B-Roll.
Second Unit
The smaller of the two crews, the second unit will focus on B-Roll footage – essentially everything else the first unit can’t film. A second unit director will head up this crew to ensure the B-Roll footage blends with the rest of the movie. Everything needs to come together perfectly to create the director’s overall vision.
For smaller film sets, both A-Roll and B-Roll will be shot by one crew and should be factored into the overarching production schedule. For the most part, it all comes down the film’s budget.
Best Practices for Shooting A-Roll & B-Roll
So, how do we shoot A-Roll and B-Roll? To maximize the effectiveness of A-Roll and B-Roll footage, you should consider:
Planning is Key
During pre-production, develop a shot list outlining both A-Roll and B-Roll to ensure you cover everything you need to. Storyboards can also be fantastic in outlining A-Roll scenes and then determining the B-Roll needed to enhance them.
Here at Celtx, we’re here to assist with all your pre-production, shooting and post-production needs. See how we can help you with your next project by clicking here.
Be Consistent
Maintain consistent lighting and color profiles across all your footage to ensure a cohesive look.
Think Variety
Capture B-Roll from multiple angles and perspectives to allow for flexibility when it comes to editing. It also allows you to select from different options and camera angles to add extra visual interest.
Stay Relevant
Ensure the B-Roll footage is pertinent to the A-Roll content and reinforces the narrative without being distracting.
From script to screen, every shot counts.
Celtx’s pre-production tools help you organize visuals before the cameras roll.
Examples of A-Roll & B-Roll in Professional Filmmaking
Now it’s time for us to see A-Roll and B-Roll footage in action! Here are some key examples from some of our favorite releases from the past few years:
1. Barbie (2023)
A-Roll
The existential conversation between Barbie (Margot Robbie) and Ruth Handler in the white void is a pivotal dialogue-heavy moment that defines the film’s overall theme.
B-Roll
Earlier in the movie, we see Barbie looking back on her memories. This enhances the dreamlike quality of her journey and providing key context to the main narrative and Barbie’s struggles reflected in the human world.
2. Dune: Part 2 (2024)
A-Roll
Dialogue and choreography drive the final minutes of this epic movie with a climactic duel between Paul Atreides (Timothée Chalamet) and Feyd-Rautha Harkonnen.
B-Roll
The sweeping desert shots of Arrakis at sunrise and the slow-motion sandworm movement creating a sense of scale are all effective uses of B-Roll here.
3. Everything Everywhere All at Once (2022)
A-Roll
The movie’s climax is an emotional conversation between Evelyn (Michelle Yeoh) and Joy (Stephanie Hsu) in the parking lot, focusing our attention on a mother and daughter who’ve struggled to find common ground.
B-Roll
Quick-cut montage of Evelyn’s alternate lives, flashing through various professions and realities both emphasize the multiversal chaos ensuing through out the movie. Also, the close-ups of the googly eyes and bagel symbol reinforce the movie’s themes.
4. Killers of the Flower Moon (2023)
A-Roll
In this confrontation between Ernest Burkhart (Leonardo DiCaprio) and William Hale (Robert De Niro), subtle facial expressions and dialogue reveal all we need to know about their dynamic.
B-Roll
The slow, atmospheric shots of Oklahoma landscapes set the historical tone of the film, and the lingering shots of oil derricks symbolize wealth and destruction. On the other hand, the close-ups of Osage traditional ceremonies are signs of looming tragedy.
What about C-Roll? Do You Need It?
We know what you’re thinking – there surely can’t be C-Roll too!
So, what is C-Roll in film? Well, beyond A-Roll and B-Roll, the term C-Roll has indeed emerged in modern video production.
C-Roll refers to footage captured without a specific purpose in mind and is often shot spontaneously during daily filming activities. It can add authenticity and spontaneity to a project but isn’t always necessary.
If you do choose to incorporate C-Roll footage into your next movie, it can provide additional material for creative editing and storytelling.
Filmmaker Christian Maté Grab puts forward a strong case for C-Roll, especially when you’re struggling to find inspiration. Check out his video below:
Tools & Software for Editing A-Roll and B-Roll Effectively
There’s no way around it. Effective editing of A-Roll and B-Roll footage requires the right tools and software. Popular video editing platforms such as Adobe Premiere Pro, Final Cut Pro, and DaVinci Resolve offer robust features for organizing, editing, and color grading footage. Plus, of course, seamlessly integrate A-Roll and B-Roll footage!
We’re very aware that all these video editing software options require a good deal of investment. Never fear, as there are some budget-friendly options available. Open-source and free software include HitFilm Express, Lightworks, Shotcut, iMovie and of course, CapCut.
How is A-Roll and B-Roll Footage Edited?
It’s all well and good having powerful and intuitive video editing software but how do we actually use them to edit? Let’s run through the process, undertaken by the post-production crew and editors:
Step 1 | Organizing Footage
Editors begin by sorting A-Roll and B-Roll clips into labelled bins or folders, ensuring easy access to both key scenes and supplementary shots.
Step 2 | Assembling the Rough Cut
A-Roll footage is placed on the primary timeline, forming the backbone of the film’s narrative as written in the script and per the director’s vision.
Step 3 | Layering B-Roll
B-Roll clips are then overlaid on top of A-Roll to smooth transitions, add visual interest, and provide contextual cutaways.
Step 4 | Using J-Cuts and L-Cuts
Here, the editors will blend A-Roll dialogue with early or lingering B-Roll visuals to create a seamless flow between visuals and audio.Want to learn more about J-Cuts and L-Cuts. Check out this awesome guide from Fandor:
Step 5 | Applying Color Grading and Effects
Consistent color correction ensures A-Roll and B-Roll match visually, maintaining a cohesive look throughout the entire movie.
Step 6 | Fine-Tuning Pacing
Editors will finish by trimming excess footage, adjusting timing. Finally, they’ll add transitions to refine the rhythm of the film’s final cut.
Conclusion
A-Roll and B-Roll are the secret ingredients that bring movies to life!
While A-Roll delivers the heart of the story with powerful dialogue, gripping performances, and action-packed sequences, B-Roll enhances it by painting vivid backdrops, building suspense, and creating seamless cinematic flow.
From sweeping deserts in Dune: Part Two to mind-bending montages in Everything Everywhere All at Once, these two elements work together to captivate audiences.
Mastering A-Roll and B-Roll isn’t just a technical skill but the key to unlocking unforgettable storytelling.
