B-roll does four different jobs, and generic footage does none of them. How to derive a b-roll list from your script, how much you need, and how to shoot it so it cuts.

To plan b-roll, work backwards from your script rather than forwards from your camera. Read the script and mark every place you will need to cut away, then write down what specific job the cutaway does at that moment: illustrating a claim, covering an edit in the main footage, giving the viewer a beat to breathe, or establishing where you are. Each marked point becomes a line on a shot list with a named subject, a framing, and a rough duration. Shoot three versions of every shot at different focal lengths, hold each for at least ten seconds, and expect to need roughly one usable b-roll shot for every twenty to thirty seconds of finished video. The alternative, which is what most people do, is to shoot a lot of attractive footage and then try to find places to use it. That produces a drive full of material that looks good in isolation and refuses to sit in the edit, because none of it was shot for a specific job. Put simply: generic b-roll is footage that fits anywhere and is needed nowhere. I have shot b-roll for documentary work where a sequence lived or died on whether we had the one specific insert that proved what someone had just claimed, and the lesson generalises hard: the value of a b-roll shot is set almost entirely at the planning stage, by whether anybody decided what it was for.
Full disclosure: Storyflow is our own product, so weigh its placement here with the skepticism you would apply to any tool a company recommends on its own blog. We rank it second rather than first. StudioBinder produces the shot list format a crewed set actually expects, and for a solo creator a spreadsheet or a notes app is lower friction, which matters more than features when the real failure mode is not planning b-roll at all. Storyflow earns its place on one specific job, keeping each shot attached to the cut point or claim in the script that generated it, and it does not schedule, produce a standard shot sheet, or track what you captured.
B-roll planning is a list derived from a script and sorted by location. The best tool is usually the one with the least friction, because the failure mode is not planning at all.
| Tool | Best For | AI Features | Price |
|---|---|---|---|
StudioBinder | Formal shot lists on a crew | Limited | ~$29 mo |
Storyflow | Deriving the list beside the script | Reads the whole board | Free / $7.99 mo |
Spreadsheet | Most solo creators | None | Free |
Notion or Apple Notes | Lowest friction | Varies | Free |
A detached wish list becomes generic footage. Keep the script and the b-roll list on one board so each shot stays tied to the cut point or claim that generated it.

A shot without a named job is a shot you will not be able to place. These are the four, and they have different requirements.
Showing what is being said. The claim is "the workshop still uses the original machines," so you show the machines. The claim is "the graph went up," so you show the graph.
What it requires: specificity. Illustrating b-roll must show the actual thing being discussed, which is why generic footage fails at this job more than any other. A stock shot of a generic factory does not illustrate a statement about this workshop.
Where it fails: vagueness. If the viewer cannot tell that this shot is the thing that was just mentioned, it is not illustrating, it is decorating.
Hiding an edit in the main footage. This is the mechanical reason b-roll exists. When you remove a stumble, a pause, or thirty seconds of tangent from a talking head, the two remaining pieces do not match and you get a visible jump. Cutting away to b-roll across the join makes the edit invisible.
What it requires: availability at the right moment, and enough length to cover the join comfortably. Covering shots do not need to be beautiful, they need to exist.
Where it fails: running out. The single most common b-roll shortage is not having anything to cut to at the exact moment you need to remove something.
Giving the viewer a beat after something dense or emotional. A held wide shot with no dialogue after a difficult admission is doing real work, and cutting it feels like tightening while actually making the piece harder to watch.
What it requires: stillness and duration. Breathing shots are usually the longest ones in the edit and the ones inexperienced editors trim first.
Where it fails: being too busy. A shot with movement or detail demands attention rather than releasing it.
Orienting the viewer in place and time. Where are we, what kind of place is this, is it morning.
What it requires: width and legibility. Establishing shots are usually wide and usually early in a sequence.
Where it fails: arriving late. An establishing shot that appears after the viewer has already worked out where they are is redundant.
The reason to name the job is that it changes what you shoot. A covering shot can be almost anything as long as it exists. An illustrating shot has exactly one correct subject. Shooting without the distinction gets you many of the first kind and none of the second, which is why sequences fall apart at precisely the moments that matter.
The method, in order.
Read the script and mark every cut point. Anywhere you will remove something, compress a tangent, or join two takes. On a scripted talking head these are predictable. On an interview-led piece, mark them after the log rather than guessing.
Mark every claim that needs showing. Anywhere the script asserts something the viewer would benefit from seeing. These become illustrating shots and they are the ones with no substitutes.
Mark the pressure points. After the densest or heaviest passage, note where the viewer needs a beat. These become breathing shots.
Mark each new location or time shift. These become establishing shots.
Convert each mark into a shot list line. Subject, framing, movement or locked off, approximate duration, and the job it serves. A line reading "detail, hands on the lathe, locked off, 15s, illustrates the craftsmanship claim at 02:40" is actionable. A line reading "workshop b-roll" is not.
Group the list by location, not by script order. You will shoot everything in one place at once, and a list ordered by script order will send you back and forth.
Add a covering surplus. Beyond the specific shots, add a handful of general-purpose covering options per location, because cut points multiply during editing and you cannot predict all of them.
The question everybody asks, with a usable answer.
Roughly one usable shot per twenty to thirty seconds of finished video. A ten-minute video needs somewhere around twenty to thirty usable b-roll shots. This is a starting estimate, not a rule, and it moves with format.
Shoot two to three times what the list says. Not more locations, more versions of the same subjects: different focal lengths and angles. This costs little on the day and saves the edit constantly.
Hold every shot for at least ten seconds. Longer than feels necessary while you are standing there, and never enough when you are editing. A shot that runs out before the sentence it is covering has ended is useless.
Formats vary predictably. A tutorial or explainer is heavy on illustrating shots because it makes claims constantly. A vlog is heavy on establishing and breathing. An interview-led documentary is heavy on covering, because you are removing a great deal of speech.
The honest test: if you have to use a shot twice in the same video, you were short. Occasional reuse is fine; noticeable reuse reads as a shortage and viewers register it even when they cannot name it.
Three versions of everything: wide, medium, and detail. This trio cuts together as a sequence on its own, which means any subject can become a five-second run rather than a single shot.
Hold still, or move deliberately. Slow drifting handheld with no intention is the least usable footage there is. Either lock it off or make the movement a decision with a beginning and an end.
Start and end the shot before and after the action. Roll for two seconds before anything happens and keep going for two seconds after. Editors need handles.
Shoot the same subject at two different moments if lighting allows. Cheap insurance against a continuity mismatch with the main footage.
Record ambient audio everywhere. Room tone and location atmosphere are the difference between b-roll that sits in the mix and b-roll that arrives as an audio hole. Thirty seconds of clean ambience per location, always.
Get the detail shots people forget: hands, textures, objects at rest, things being put down, a door opening. These cover almost anything and give an edit texture.
Avoid faces you have not cleared, particularly in public places, and get releases where you need them.
The most common use case, with its own logic.
Cover is the dominant job. Most YouTube editing removes a large proportion of what was said, and every removal needs covering. Plan more covering shots than feels reasonable.
Illustrate anything you claim. Retention improves when the viewer sees the thing under discussion rather than a person describing it, and this is the mechanism, not a mystical engagement trick.
Screen recordings count as b-roll, and for software or tutorial content they are usually the primary b-roll source. Plan them as shots with subjects and durations, not as an afterthought.
Cut to b-roll before the viewer gets bored, not after. The standard practice of changing the image every several seconds is really a way of ensuring you never sit on a static frame long enough for attention to drift.
Do not cut away during the emotional or important line. The face is doing the work there, and cutting away throws it out. Cover the setup and the aftermath, not the moment.
Worth separating, because the standard advice actively misleads here.
Illustrating shots carry the argument. When a contributor claims something, the shot that shows it is doing evidential work. This is the difference between a film that asserts and a film that demonstrates.
You often cannot restage it, so the shot list is a list of things to look for rather than things to set up. Documentary b-roll planning is closer to a hunting list than a shot list.
Shoot the ordinary things immediately. The routine details of a place are what you will need and are the easiest to assume you can get later. You frequently cannot; access changes.
Observational footage of people doing things beats abstract texture for nearly every documentary purpose, because it carries information as well as atmosphere.
Archive and stills are b-roll too, and their availability should be established during research rather than discovered in the edit.
Shoot it yourself where the shot must be specific. Anything illustrating a particular claim about a particular subject has to be real.
Stock is acceptable for establishing and breathing, where the requirement is a category of image rather than a specific one. Check the licence covers your use, including monetised video.
Archive footage needs clearance and often payment, and the lead time is real. Establish availability during research.
Generated footage is now viable for certain abstract and illustrative shots. Two honest cautions: platform and client disclosure expectations are changing quickly, so check what applies to you, and generated footage cannot serve the evidential job at all, because the entire value of an illustrating shot in factual work is that it is real.
Keep the original audio underneath. Cutting to b-roll while the interview or voiceover continues is the standard construction. The b-roll's own audio usually sits low in the mix as texture rather than replacing anything.
Cut on the sentence, not mid-phrase, unless you are deliberately covering a join, in which case cut where the edit is.
Let establishing shots run. They are doing orientation work and clipping them to a beat defeats the purpose.
If a shot has no job, remove it. A shot included because it is beautiful and not because it is needed is the most common cause of a video that feels padded.
Best for a formal shot list: StudioBinder. Purpose-built shot listing with framing, movement, and equipment fields, tied to a schedule. The right choice on a crewed production. Free tier, paid from around $29/month (verify current pricing).
Best for deriving the list from the script: Storyflow. The canvas where the script sits beside the b-roll list, so each shot is attached to the cut point or claim that generated it and the AI can read both together. Free plan is $0; Plus is $7.99/month billed annually. The honest limit: it is not a shot list format anyone on a crewed set expects, and it does not schedule.
Best free option: a spreadsheet. Columns for subject, framing, duration, job, and location, sorted by location for the shoot day. What most creators actually use, and sufficient.
Best for solo creators already working in a notes app: Notion or Apple Notes. Lower friction than any dedicated tool, and friction is what actually stops people from planning b-roll at all.
| Tool | Best for | Ties shots to the script | Free tier | Starting price |
|---|---|---|---|---|
StudioBinder | Formal shot lists on a crew | Partially | Yes | ~$29/mo |
Storyflow | Deriving the list beside the script | Yes | Yes, unlimited boards | $7.99/mo annual |
Spreadsheet | Most solo creators | No | Yes | Free |
Notion or Apple Notes | Lowest friction | No | Yes | Free |
Pricing checked July 2026. Competitor pricing changes often and varies by plan and region, so verify on each vendor's page before quoting it.
Shooting without naming the job. Produces footage that fits anywhere and is needed nowhere.
Too few covering shots. The most common actual shortage, discovered at the worst time.
Shots that are too short. Ten seconds minimum. Editors need handles.
Only one version of each subject. Wide, medium, and detail cost thirty extra seconds and save the edit repeatedly.
No ambient audio. B-roll arrives as an audio hole and the mix suffers.
Cutting away during the important line. The face was doing the work.
Reusing the same shot several times. Reads as a shortage even when the viewer cannot name it.
Using stock for illustrating shots in factual work. It does not illustrate, it decorates, and in documentary it quietly undermines the claim.
B-roll planning fails for one reason, and it is not laziness. People shoot without deciding what each shot is for, because deciding is harder than filming, and attractive footage feels like progress.
Name the job first. Illustrate, cover, breathe, establish. Derive the list from the script's cut points and claims rather than from what looks good at the location. Shoot three versions, hold them longer than feels sensible, and record the room.
Do that and the edit becomes assembly rather than rescue. Skip it and you will have a drive full of good-looking shots and nothing to cut to at 04:12, which is the only moment that mattered. Generic B-roll is footage that fits anywhere and is needed nowhere.
B-roll is supplementary footage cut in alongside the main footage, which is the a-roll. It does four jobs: illustrating what is being said, covering edits in the main footage so joins are invisible, giving the viewer a beat to breathe, and establishing where and when a scene takes place.
Work from the script rather than the location. Mark every cut point, every claim that needs showing, every place the viewer needs a beat, and every location or time change. Convert each mark into a shot list line with a subject, framing, duration, and the job it serves, then group the list by location for the shoot day.
As a starting estimate, one usable shot per twenty to thirty seconds of finished video, so roughly twenty to thirty shots for a ten-minute piece. Shoot two to three times that in versions rather than subjects, meaning different focal lengths and angles of the same things, and hold every shot for at least ten seconds.
A-roll is the primary footage carrying the content, typically the person speaking or the main action. B-roll is everything cut in around it. The distinction matters mainly because a-roll cannot usually be cut without a visible jump, which is precisely the problem b-roll solves.
Record at least ten seconds per shot, longer for anything you expect to use as a breathing beat. In the finished edit individual shots often run only two to five seconds, but the extra recorded length gives the editor handles and covers longer joins when a cut takes more time than expected.
For establishing and breathing shots, yes, where the requirement is a category of image rather than a specific one. For illustrating shots it usually fails, because the value of an illustrating shot is that it shows the actual thing being discussed. In factual and documentary work, stock standing in for a specific claim is a credibility problem.
Predominantly covering shots, because most talking head editing removes a large proportion of what was said and every removal needs hiding. Add illustrating shots for anything the script claims, and for software or tutorial content treat screen recordings as your primary b-roll and plan them as real shots with subjects and durations.
Three versions of each subject at wide, medium, and detail framing. Hold still or move with clear intent rather than drifting. Roll for two seconds before and after the action. Record thirty seconds of ambient audio at every location. And get the small detail shots, hands, textures, objects, doors, because they cover almost anything.
Record it always, use it low. The standard construction keeps the interview or voiceover audio running underneath while the b-roll's own ambience sits beneath it as texture. B-roll cut in with no accompanying audio produces a noticeable hole in the mix.
During the emotionally or informationally important line, where the speaker's face is doing the work. Cover the setup and the aftermath instead. Also avoid cutting away simply because a shot is attractive: if a shot has no job at that moment, it makes the piece feel padded.
Yes, for the derivation step. Keeping the script and the b-roll list on one canvas means each shot stays attached to the cut point or claim that generated it, rather than becoming a detached wish list, and the AI can read both together. Free to start.
Three places. It does not produce a shot list in the format a crewed set expects, so StudioBinder or a printed sheet is better once other people are involved. It does not schedule, so shoot-day ordering happens elsewhere. And it does not hold footage, so tracking what you actually captured against the list happens in your NLE.
Every Storyflow board starts from real structure and an AI that reads the whole canvas. Open one of these templates and make it yours.
A visual AI workspace where every feature lives inside one canvas. No tab-switching, no context lost.
Build your entire board from a single message
Type what you need in the AI chat at the bottom of your canvas. The AI adds cards, headings, and structure directly onto your board.
Use expert frameworks as AI context
Type @ in the AI chat and choose any Tactic. The AI tailors every response to that framework instead of giving generic advice.
Turn your board into a mind map in seconds
Ask the AI to restructure your canvas as a mindmap. It connects your ideas into a visual hierarchy so you can see how everything relates.
Storyflow actually began as a personal tool while working on creative and research projects.
We kept running into the same problem: ideas were scattered everywhere: notes, documents, and whiteboards.
Nothing helped us see how everything connected.
So we started building a workspace designed around how ideas actually grow.
