B-roll mistakes: the footage is innocent, the choices are not
Bad b-roll is rarely bad footage. It is decent footage doing the wrong job: decorating instead of showing, arriving beside the words instead of on them, or burying the person the viewer came to watch. Here are the five mistakes that do most of the damage, what each looks like from the viewer's side, and the fix.

Mistake 1: wallpaper b-roll
Wallpaper is a clip that is merely on: a drone shot under a sentence about pricing, an office pan under a story about a customer. It moves, it fills the frame, and it shows nothing the sentence mentioned.
The viewer does not consciously object. They just stop connecting picture to voice, and once that link breaks, every later cutaway works less.
The test is blunt. Pause on any cutaway and ask what it just showed that the words did not carry. If the honest answer is nothing, but it looked nice, it is wallpaper.
The fix is deletion. An uncovered sentence is not a problem. A covered one that shows nothing is.
Mistake 2: the shot and the words disagree
The ear and the eye check each other constantly. When the picture runs a beat behind the voice, or lands on a phrase it has nothing to do with, the video feels dubbed, and the viewer cannot say why.
The second version is the wrong-meaning shot: a word with two readings gets the other one. Say margin and the clip shows the edge of a page. These are direct hits on the wrong target, and they read as broken.
Both come from the same cause: placement by area rather than by word. On a timeline, a clip is put roughly where the sentence should be, and roughly is the whole problem.
The fix is checking every cutaway against the exact words beneath it, and moving the clip until the two agree. Tedious by hand, which is why it is the most shipped mistake on this page.
This is the whole editor
Highlight a phrase and a clip lands on those exact words. No timeline, no keyframes, no layers.
Mistake 3: burying the face
Every added clip costs seconds of the person, and the person is the format. Past roughly half the runtime, a talking head video quietly becomes narrated stock, and the trust that made it work leaves with the face.
The instinct that causes it is real: by your fourth watch, the take feels repetitive and coverage feels like the cure. To a viewer seeing it once, it was not repetitive yet.
Working ceilings, by editing pace: 40 percent of runtime covered at a calm pace, 45 at normal, 52 at fast. The two most expensive places to be covered are the opening seconds and the final ask.
The fix is counting seconds of coverage, not clips, and stopping at the ceiling even when the shelf still has good footage on it.
Mistake 4: the cliches
Some clips have been in so many videos that they no longer show anything: they just say advertisement. The handshake. The typing hands. The skyline timelapse. The meeting where everyone laughs at a laptop. The slow motion coffee pour.
The damage is specific: trained by thousands of feeds, the viewer's eye disengages the moment one appears, which is usually the moment you needed attention most.
Each cliche has a specific version that still works, because specificity is what the cliche is missing.
- The handshake: replace with the moment your work changes hands. Keys, report, finished product.
- Typing hands: replace with your actual screen, recorded, sensitive numbers blurred.
- The skyline: replace with the street your customers walk down.
- The laughing meeting: replace with your whiteboard filling up in real time.
- The coffee pour: replace with the first sale of the morning going through the till.
Mistake 5: no breathing room
An edit where every second is covered, captioned, zoomed and scored has no way to say this part matters. When everything is emphasised, emphasis stops existing.
Returns to the face are the punctuation. Two seconds of just the speaker between cutaways re-anchors the viewer and makes the next clip land as a choice instead of a reflex.
The sentence you most need believed should stand alone: no cutaway, no competing motion. Cover the stretches around it and the contrast does the pointing for you.
The fix is coverage in clusters, with deliberate gaps, instead of an even coat across the whole read.
Three of the five are placement, and placement is what a transcript fixes
Wallpaper, missed words and wall-to-wall coverage are not footage problems. They are what a timeline produces under deadline, because a timeline thinks in seconds while you think in sentences.
Cutroom places b-roll on the exact words spoken. You direct on the transcript: highlight a phrase and the clip covers those words, not the neighbourhood around them. Coverage is capped at 40, 45 or 52 percent by the pace you pick, so mistake three cannot ship by accident. When no clip matches a phrase well, the slot stays on your face rather than being filled with wallpaper.
The cliche-spotting stays yours: highlight a generic phrase and you will get a generic clip. Swaps cost nothing, and your own footage is matched ahead of stock.
One talking take of up to 3 minutes in, a finished 9:16 MP4 out in about a minute. A batch is 100 credits and export adds 20 credits per finished minute, so a 30 second video is about 110 credits. Three finished videos are free inside your first seven days, no card, on the 600 credits granted at signup, and they export with a Cutroom mark across the middle. Lite is $19.99 a month for 1,250 credits, about 11 of those, nothing on the picture, cancel in one click.
Questions people ask
- Is using no b-roll at all a mistake?
- No. A bare talking head is a working format on its own. Every mistake on this page is b-roll used badly, and all five are worse than the plain version they were meant to improve.
- How do I know if my b-roll is wallpaper?
- Pause on the clip and name what it just showed that the sentence did not already carry. If you cannot, the clip is decorating. Delete it and let the speaker have the seconds.
- Are the stock cliches ever acceptable?
- In a passing mention of a generic noun, briefly, yes. Three seconds of city under the words across the country harms nothing. The cliche becomes a mistake when it stands in for something specific about you.
- How much breathing room does an edit need?
- Enough that the viewer returns to the face between clusters of coverage, and a clean stretch of just the speaker around the one sentence that matters most. As a floor, if there is no two-second gap anywhere, the edit has none.
- Does Cutroom prevent these mistakes automatically?
- Two of them structurally: clips are anchored to words so they cannot drift, and coverage cannot pass the ceiling for your pace. It also skips a slot rather than forcing a weak match. Judging wallpaper and cliches stays your call, which is why every placement can be swapped at no cost.
Every mistake here survives good footage, and dies with one question asked per clip: what is this shot showing that the sentence could not. Ask it five times a video, and the b-roll stops being the reason a good take looks cheap.
