Stock libraries are full of offices and skylines. Sometimes your script needs a dinosaur. Or a shark. Or a police car pulling up outside a shop — whatever makes the viewer smile and remember the point. With keyword-driven B-roll search in MicroBiz365’s editor, you type the idea; the tool fetches matching clips from Pexels and lets you drop them on the timeline. It is not generative AI inventing pixels from scratch — it is fast, searchable stock aligned to your words.

How keyword B-roll matching works

You enter search phrases — one per line — such as “dinosaur museum exhibit”, “shark underwater”, “police car city night”. The editor requests clips via the MicroBiz365 fetch API, downloads proxy-friendly previews, and places candidates on the B-roll lane. You drag the best segment onto Video 1 while your narration continues.

Because search is literal, choose phrases stock libraries actually contain. “Volcano eruption aerial” works; “my exact shop on High Street” will not — film that yourself.

Examples that work on camera-heavy channels

Education: dinosaur skeleton when mentioning extinction risk metaphors.
True crime adjacent marketing: police tape and city B-roll when discussing compliance audits (use responsibly).
Travel: sharks when discussing “predatory fees”.
Kids’ products: colourful fairground B-roll when talking about joy — not only toy close-ups.

Humour and surprise increase shares; just keep the clip relevant to the sentence under it, or viewers feel baited.

Works independently of your video content

Your A-roll can be a plain talking head in a spare room while B-roll carries the imagination. That decoupling is powerful for creators who film in one location but speak about big ideas. The voice sells the insight; the pictures stop the scroll.

You do not need a transcript: type keywords directly and hit re-fetch. Transcripts still help when you want automated suggestions from your actual words.

Limits to stay honest about

Results depend on stock library contents and API configuration.
Unusual prompts may return loose matches — review every clip.
Licences follow Pexels terms; read them for commercial use.
Very long timelines or huge files may export slowly in the browser.

Combine wild B-roll with discipline

One dinosaur joke can sparkle; five in a row feels like a meme account. Use surprising cutaways at chapter changes, then return to calm footage so trust rebuilds.

Keyword prompts that actually return results

Think like a stock site indexer, not like a novelist.

dinosaur skeleton museum hall
great white shark ocean slow motion
police car urban night lights
volcano lava aerial daytime
lightning storm clouds timelapse
rocket launch smoke daylight
medieval castle drone establishing

Avoid stacking adjectives — “scary angry dinosaur destroying London” may return nothing useful. Try two searches and pick the best clip from each.

Workflow with transcript vs without

With transcript: transcribe Video 1, let the tool propose keyword lines from your speech, then edit the list before fetch. Without transcript: type five lines yourself — faster when you already wrote a blog post or script. Re-fetch after you change lines; old clips stay on the lane until you remove them.

AI B-roll and truth in advertising

Surprise footage must not mislead. If you sell regulated financial services, a shark metaphor is humour — not a claim about risk. If you show police tape, clarify it is illustrative. UK advertising standards still apply to your words; visuals amplify them.

Performance tips for heavy stock timelines

Several HD stock clips on one timeline increase export time. Export when you are on power, not battery. Close other tabs. If export fails, shorten the timeline or remove one 4K stock piece.

Teaching and kids’ content without filming a zoo

Tutors explaining dinosaurs can fetch museum B-roll instead of travelling. Swim schools can show underwater stock while the coach narrates safety rules on deck. The picture supports imagination; your face still carries authority when you cut back to A-roll.

Seasonal campaigns

Retailers can type “Christmas market lights”, “summer festival crowd”, or “Black Friday shopping bags” for timely cutaways while the owner films themselves in the shop. Seasonal stock plus one day of custom footage beats either approach alone.

Review each clip before you place it

Stock search is fast; curation is slow. Watch each candidate for accidental logos, wrong country road signs, or dated fashion if your brand is modern. Reject loose matches — viewers forgive missing B-roll more than wrong B-roll.

From keyword to timeline in five minutes

Upload Video 1 and wait for filmstrips to appear.
Type three to five literal search lines in Step 3.
Re-fetch B-roll and skim thumbnails on the library lane.
Drag the best two seconds of each clip onto Video 1 at script beats.
Export a thirty-second test before you commit to a ten-minute timeline.

That test export costs little time and proves the API, browser memory, and music mix are healthy before a long session.

Humour without losing trust

A dinosaur in a finance video works when you label it metaphor in the script — “extinct fees”, not “actual dinosaur on your balance sheet”. The joke lands in the contrast between your calm face and the absurd image. Follow with a straight cut back to A-roll so the audience knows you are still serious.

When keyword search is not “AI video generation”

Some creators expect typing “dragon” to synthesise a new creature. This editor searches stock libraries, similar to typing into a footage site. You choose from real clips photographers filmed. That keeps results grounded and avoids uncanny generated faces — but it also means impossible literal scenes need creative wording or your own uploads.

Building a personal prompt list

Keep a notes file of ten phrases that worked: shark, volcano, police lights, dinosaur skeleton, and so on. Reuse them across videos with different narration so you build a visual style subscribers recognise. Pair wild cutaways with calm A-roll and viewers learn your rhythm: insight first, punchline picture second, back to your face for the call to action.

Pexels and attribution

Fetched clips come from stock providers; check current licence text on the provider site for commercial use and attribution. If a clip feels off-brand, skip it — keyword search is cheap, your reputation is not.

Combine with custom uploads in one project

Use keyword stock for the joke or metaphor; upload your own clip for the product payoff. Both sit on the B-roll lane until you commit them to Video 1 — order does not matter, placement does.

Ideas for UK small-business channels

Estate agent: kettle boiling, keys on counter, street establishing. Dog walker: leash clip, park wide, happy dog close-up. Accountant: calculator, inbox zero, calendar flip. Type those literals into keyword search when you have no time to film this week.

Save your best keyword lines in a note app — creators who reuse prompts spend less time searching and more time publishing.

Next step

Open the Simple Video Editor, type three bold keyword lines that fit your next script, place one unexpected (but relevant) cutaway, and export. Then read the other guides on the MicroBiz365 tools hub for music, two-camera sync, and copyright-safe habits.
