Explainer video examples: five real films and what makes each one work

What these examples have in common

Every film below was made with Voom from a short prompt, two of them also from a website link. They cover four kinds of topic and run from 30 to 80 seconds. What they share is the shape that makes any explainer work:

1. They open on the viewer’s question or problem, not on a company name.
2. They answer it in one plain line before the detail.
3. Every step or actor gets one simple picture that stays the same all film.
4. They end on a phrase the viewer can repeat, or one clear action.

Each example links to the film’s own page, with its full transcript and settings.

1. How a UPI payment moves (fintech, 80 seconds)

The prompt: “Explain how a UPI payment moves money from one bank account to another in about two seconds, for people in India who are new to paying by phone. Walk through who talks to whom: your app, your bank, NPCI, the other bank, and the PIN that only you know.” Watch the film.

What works:

• 0:00 It opens on a feeling every newcomer has: you tap Pay and the money just leaves. Where does it go?
• 0:07 The first answer is a surprise that reframes the question: the app is only the front door, it does not move the money.
• 0:24 Each actor gets one shape for the whole film: banks are buildings, NPCI is a dial between them, the PIN is four dots beside a lock.
• 0:57 The ending redraws the whole route on a blackboard, so the viewer leaves with the full picture rather than the last step.

Why this length: five actors and a round trip need time. At 80 seconds, each step gets its own line and nothing is rushed.

2. How Zyflow works (SaaS, 75 seconds)

The prompt: “A 75-second explainer for Zyflow: how a freelancer’s working day changes when their CRM lives inside the AI app they already use”, with the product’s site, zyflowcrm.com. Watch the film.

What works:

• 0:00 It starts with a habit the viewer already has: telling an AI about a client, then losing it when the tab closes.
• 0:14 Instead of a feature list, three real screens from the site walk through a working day: the morning list, a payment reminder and an invoice from one sentence.
• 0:29 The key benefit is shown, not claimed: a note saved on Monday in one app answers a question on Tuesday in another.
• 0:36 The trust section, four guardrails, lights each name as it is spoken, so the viewer reads and hears it at once.

Why it works for software: the product’s own screens, in its own colours and type, make the film look like the thing the viewer will sign up for.

3. How a heat pump warms a home (science, 45 seconds)

The prompt: “Explain how a heat pump keeps a home warm in winter by moving heat instead of making it. Friendly and clear, for homeowners.” Watch the film.

What works:

• 0:00 A girl at a window on a cold night and a handwritten question: where does the heat come from?
• 0:05 The answer comes first, in six words: it moves heat, it doesn’t make it.
• 0:13 Three steps, three short labels: soak it up, squeeze it hot, warm the room.
• 0:37 It ends on a phrase built to be remembered: moved, not made.

Why this style: a warm cut-paper world makes a technical topic feel approachable for homeowners who are not engineers.

4. How a solar panel makes electricity (science, 45 seconds)

The prompt: “Explain how a solar panel turns sunlight into electricity, for curious homeowners.” Watch the film.

What works:

• 0:00 The question belongs to a person, Omar, looking up at his roof, which makes it the viewer’s question too.
• 0:12 One abstract idea, electrons flowing one way, gets one picture, and the voice names it: that flow is current.
• 0:20 The step most people skip, the inverter, gets its own line.
• 0:32 The recap is a rhythm: sunlight in, power out.

Why it is short: one concept, four steps. 45 seconds is enough, and more would mean padding.

5. A company intro for a service business (30 seconds)

The prompt: a 30-second brand film for Helcyn Technologies, a founder-led engineering studio, starring its mascot, with its site helcyn.com. Watch the film.

What works:

• 0:00 It speaks to the client first: you’ve got something worth building.
• 0:03 Four capability cards turn an abstract service into things you can count.
• 0:08 A timeline makes a promise concrete: a working product in six to eight weeks.
• 0:20 It ends on one action and nothing else: book a 30-minute call.

Why it works without product pictures: a service has nothing to photograph, so the film is built purely from motion graphics and the company’s own mascot.
