B-roll is supporting footage used alongside the main action or interview, often called A-roll. It can show what a speaker means, establish a location, bridge an edit or add a reaction. Its job is to help the sequence, not simply make a cut busier.
Download the B-roll shot list and edit worksheet (ZIP; open the HTML file inside). The example follows a fictional maker packing a repaired lamp. It is a planning demonstration, not a permission-cleared filmed production.
How the coverage solves an edit
Suppose the maker says, “I replaced the switch,” then pauses before explaining how the lamp was packed. Keep the useful spoken lines as A-roll. A detail of the actual switch can illustrate the repair; a continuous shot of wrapping the lamp can cover the removed pause. Return to the maker when their expression adds meaning.
The inserted image must support the statement. Do not show a different repair as if it documents the one described. In factual work, an attractive shot can still mislead if the edit implies an event or sequence that did not occur.
| Coverage | Example | Why it helps |
|---|---|---|
| Wide | Maker and workbench | Shows the location and spatial relationships. |
| Medium | Maker lowering the lamp into a box | Carries the complete action. |
| Detail | Switch, cord, label | Shows a specific object or claim. |
| Action | Hands wrapping the lamp | Provides continuity across a dialogue edit. |
| Reaction | Maker checking the package | Adds a closing beat or response. |
A-roll and B-roll describe a job in the edit
A-roll carries the main scene, interview or argument. B-roll supplies supporting images in that particular sequence. The distinction is not a quality rating and does not mean footage from camera A versus camera B. A second camera recording the main interview may still be part of the primary coverage. A close-up of a repair could be supporting footage under an interview, then become the main action in a wordless demonstration.
An insert shows a detail within the action, such as a hand turning the lamp switch. A cutaway moves attention elsewhere, such as the customer waiting across the room. An establishing shot gives location context. These describe different functions that supporting footage can perform; they are not interchangeable requests to a camera operator.
Turn interview points into a useful shot list
Before filming, list the statements you expect the subject to make and the images that could support them honestly. After the interview, revise that list against what was actually said. “The repair took a long time” may need evidence of stages or a specific explanation; an unrelated clock shot does not document elapsed time.
| Story point | Possible coverage | Question to resolve |
|---|---|---|
| The lamp arrived damaged. | Its actual damaged switch or a clearly identified earlier photograph. | Does the image depict this lamp before repair? |
| The maker explains the replacement. | A view showing the relevant component and the maker indicating it. | Can the audience tell what changed? |
| The repaired object is ready to leave. | Complete packing action, then the finished package. | Can the action be covered without an unexplained reset? |
| The work matters to the customer. | A genuine response or the customer’s own explanation. | Would moving the reaction imply a response they did not make? |
In b-roll-shot-list.html, use the editable notes to connect each planned shot to its purpose, action and continuity requirement. Add real clip identifiers after capture. Mark missing coverage before leaving the location, and save or print the working sheet. The worksheet is a planning aid, not a filmed example or a media-asset manager.
Capture a sequence, not a collection of fragments
For a repeatable action, begin with a frame that explains the whole operation. Follow with a closer view that shows the important action clearly, then a detail that the wider frame cannot communicate. In the packing example, the useful sequence is not simply “wide, medium, close.” It is an empty box being prepared, the lamp being lowered inside, protective material being added and the box being closed.
Watch what changes between angles. If tape appears on the box before the shot in which it is applied, the editor needs another route through the sequence. Record the complete action from the chosen angle where possible, including the approach and release of a hand. A beautiful two-second fragment may give the editor no place to enter or leave.
For unrepeatable events, prioritize the meaningful action while it happens. Do not interrupt an event merely to satisfy an ideal list of shot sizes. A later detail can explain an object, but it should not be presented as a contemporaneous action if that would mislead viewers.
Edit the sound and image as connected layers
- Build the primary story. Choose the spoken passage or action that carries the sequence. Remove repetition while preserving the speaker’s meaning.
- Mark the visual needs. Identify where viewers need evidence, context, a detail or a way across a visible edit.
- Place the relevant image. Let the supporting shot remain long enough for its information to register. Avoid cutting to every noun merely because footage exists.
- Shape the sound transition. Let interview audio continue beneath supporting images where appropriate. Add the location’s useful natural sound deliberately; do not leave accidental handling noise mixed in.
- Watch the whole sequence. Check that object state, screen direction, lighting and implied chronology remain understandable.
When audio from the incoming shot begins before its picture, editors commonly call that a J-cut. When outgoing audio continues after the picture changes, it is commonly called an L-cut. Adobe’s split-edit guide explains these audio-picture relationships. The technique helps shape an interview sequence; it does not excuse altering the meaning of a statement.
Avoid the three easy ways to weaken B-roll
Every shot moves: movement can distract from the object the viewer needs to inspect. Capture a usable held frame as well as an intentional move. Every shot is slow motion: altered speed changes the perceived action and can make real-time processes hard to understand. Every edit is hidden: a speaker’s face may carry the most important information. Return to it when the performance matters more than another illustrative image.
Capture enough handles and continuity
Begin recording before the useful action and keep recording after it settles. Match hand use, object positions and direction between takes. If an action cannot be repeated, prioritize complete coverage and factual continuity over a decorative insert. Record useful natural sound separately from camera handling noise.
Shot size and lens focal length are different choices. The wide-shot guide explains framing; high angles and Dutch angles should serve a reason in the scene rather than decorate every insert.
Choose stock footage by license and meaning
Read the actual license for commercial use, editorial-only restrictions, attribution, identifiable people/property and permitted distribution. “Available online” and “royalty-free” do not mean unrestricted. Keep the receipt/license and source with the edit. Music also needs the relevant rights; the US Copyright Office guidance distinguishes composition and recording permissions.
Before you leave the location
- Check a wide view, complete action, useful detail and reaction against the story.
- Listen to the recording and capture room tone where needed.
- Log what each shot actually depicts and any permission restrictions.
- Verify the files and a second copy before clearing media.
Use the coverage in the short-film workflow or organize it into the sizzle-reel beat sheet.
