What Is an Explainer Video? (Definition, Types & When to Use One)

If you have ever tried to explain a product in a sales deck and watched eyes glaze over by slide four, you already know the job an explainer video is hired to do: make one idea land, then point to a next step — not “look cinematic” or “use every feature we shipped.”

This guide covers the definition, formats, a decision table versus promo and demo, when you actually need one, and how we make them at Animation Explainers. Long hub: explainer videos guide.

What is an explainer video? (short definition)

An explainer video is a short film — typically 60 to 90 seconds — that explains one product, service or idea in plain language, usually with a voiceover and animation. It turns a pitch deck or product page into a single visual argument so a busy viewer can grasp the offer and know what to do next.

That is the cite-ready definition. Length and style flex; the job does not. One idea, a clear story, a finish that does not fizzle.

Why explainer videos work for B2B

B2B buying is rarely impulse. Buyers need to recognise a problem, see a solution, and feel confident enough to book a call or start a trial. Written copy can do that, but it asks for time most homepage visitors will not give.

An animated explainer helps because it:

• Controls the narrative. You set the order: problem → solution → proof → call to action.
• Makes abstract products concrete. Software, platforms and processes are hard to “show” with a photo. Animation visualises workflows and outcomes without filming a warehouse.
• Travels well. One master can sit on a homepage, landing page, LinkedIn, YouTube, sales email and booth loop.
• Stays on-brand. Characters, colour and tone match guidelines more tightly than a rushed live shoot.
• Scales across markets. Swap the voiceover language; keep the visuals — often cheaper than reshooting live action per region.

SaaS teams lean on this heavily — see SaaS explainer videos. Healthcare and life sciences often need the same clarity with higher visual fidelity; that is where medical animation earns its keep.

No magical conversion percentages required. Honest script, short story, clear CTA — miss those three and no style will save you.

Explainer vs promo vs demo vs product demo

“Explainer” is a job, not a look. Promo, demo and product demo are different jobs. Mix them up and you either bore cold traffic with a click-path, or you spend a launch budget on vibes when the buyer still cannot say what you do.

	Explainer	Promo / brand film	Demo	Product demo
Job	Make one idea understood, then a next step	Make people feel something about the brand or campaign	Show a workflow or pitch as it actually runs	Show the product UI / features in use
Typical length	60–90 seconds	15–60s for ads; longer for brand films	Often 2–10 minutes	60 seconds to several minutes
Hero asset	Script + visual argument (often animation)	Look, music, talent, campaign hook	Presenter, customer or AE walking through	Screen, cursor, sometimes VO
Best home	Homepage, paid landing, sales opener	Social, campaign, brand hub	Late-funnel sales, webinars	Product page, onboarding, help
Fails when	You cram the whole catalogue in	The viewer still cannot explain the offer	You play it to people who are not ready	You use it as a cold homepage story

They are cousins, not substitutes. Plenty of teams need an explainer and a product demo: explainer on the homepage, demo deeper in the funnel. A promo can sit around a launch. A twelve-minute screencast tutorial belongs in the help centre, not in the hero.

If you catch yourself saying “we need a video,” pause and pick a column. Brief, length and budget all follow from that.

When a business actually needs one (and when it does not)

You probably need an explainer if:

• A new product, feature or category still takes a clever colleague fifteen minutes to describe
• The homepage or paid landing has a complex offer and a bounce problem that copy alone is not fixing
• Sales repeats the same pitch on every call and would rather send a 90-second film first
• You are rolling out across markets and need one visual system plus several languages
• An internal change programme needs clarity without a lecture

Wait — or pick a different format — if:

• Positioning is still changing weekly. Lock the message before you lock pictures.
• Stakeholders cannot agree on a single CTA. “Learn more, book a demo, and download the white paper” is three videos pretending to be one.
• You actually need a tutorial, testimonial reel, or feature walkthrough, not a story
• You only want “something animated” with no audience or outcome defined
• The product will be unrecognisable in six weeks and you will not treat the film as a snapshot

A studio can help sharpen a fuzzy brief. It cannot invent strategy you do not have.

Formats: animation, live action and screencast

Tech blogs often list eight “types”: 2D, whiteboard, motion graphics, 3D, live action, screencast, tutorial, product demo. Useful as a menu. Confusing as a brief.

Treat the last few as formats for the same job — explaining — then choose what fits the buyer and channel.

Format	What it is	When it earns its place	Honest limit
Custom animation	2D, whiteboard, motion graphics, 3D, hand-drawn — built for the brand	Abstract products, processes, multi-market reuse, tight brand control	Costs more than a template; worth it when the film is the face of the offer
Live action	People, places, real environments	Founder, clinician or customer is the message; physical proof	Reshoots, locations, localisation; harder to update
Screencast	The UI as it is, often with a cursor and VO	Tutorials, onboarding, late-funnel product demos	Cold traffic wants the why, not a click-path

We make custom animation. We are not a Camtasia shop, and we will not pretend a 60-second brand film is the same job as a ten-minute product tutorial. Need the tutorial? Record it in-house or with a demo specialist. Need a homepage or launch film that makes an abstract B2B product make sense? That is the work.

Templates versus studio: DIY template tools are fine for a social test or an internal draft. They are a poor public face for a serious B2B product — stock characters, limited motion, a look half your category already rented. Custom studio work costs more because every asset is yours, which also makes localisation and future edits cleaner. See the difference in our portfolio.

Types of animated explainer (and when each fits)

Once you have chosen animation, style is how it looks. Brand, audience, complexity and budget decide. Our animation styles overview covers the wider menu; marketers ask about these most.

2D animation

Flat characters, scenes and icons. Versatile, readable, and usually the workhorse for product and brand explainers — SaaS, fintech, HR tech and most B2B services.

Whiteboard animation

A hand draws diagrams and icons as the voiceover talks. Educational and low-distraction — ideal for processes, training and “teacher at the board” concepts. Often toward the more accessible end of a studio budget. More: what is whiteboard animation?

Motion graphics

Typography, charts, UI elements and abstract shapes moving with the story. Excellent when the product is the interface, or you want polish without character comedy.

3D animation

Depth, lighting and modelled environments — physical products, machinery, spaces, or (in healthcare) anatomy and devices. More labour-intensive, so it sits higher in the cost conversation.

Hand-drawn / illustrative

Frame-by-frame or heavily illustrated 2D with a crafted line. Strong for founder stories and purpose-led brands. See hand-drawn explainer videos.

Product-focused explainers

Sometimes the “type” is purpose, not style: a product explainer video zeroes in on how the thing works and who it is for, whether visuals are 2D, motion graphics or a hybrid.

You can mix styles (e.g. motion graphics for UI inside a 2D piece) as long as the overall look feels intentional.

How long should it be? (one idea, then stop)

In our experience, an effective marketing explainer should be between 60 and 90 seconds. Long enough for problem, solution and CTA; short enough that people finish it on a homepage or LinkedIn feed.

One idea per video. If you cannot say the point in a sentence, you do not have an explainer yet — you have a brochure with a voiceover. The visual argument should resolve: here is the friction, here is what changes, here is what to do. Catalogue tours belong in a demo.

• Under 60 seconds can work for a very simple offer or a social cut-down. Treat 30 seconds as a ruthless edit, not a second strategy.
• 60–90 seconds is the homepage / launch sweet spot.
• Longer than 90 seconds is fine for training or multi-step demos — a different brief, not a stretched spot.

If everything feels essential, the script needs another pass, not another thirty seconds.

Mute, captions, and where the video lives

A lot of B2B video is watched with the sound off — LinkedIn especially, and plenty of homepage autoplay. Design for mute first: captions, titles and on-screen labels should carry the story without the VO. Then add a human voiceover for people who unmute. Captions are how the idea survives the feed.

Where it should live (one master, several homes):

• Homepage hero — the “what is this?” story for first-time visitors
• Paid landing pages — same idea, tighter CTA, match the ad promise
• Product or solutions pages — a product explainer angle
• Sales decks, emails and proposals — send before the call
• Social and YouTube — native captions; square or vertical cuts if scoped
• Events and booth loops — often mute-first, so the first three seconds must read as a poster

Do not ask one 90-second film to be a tutorial, a testimonial and a brand anthem. Cut-downs are cheap compared with a confused master.

Script, story and CTA: what makes one “good”

Fancy animation on a muddy script is just expensive confusion.

Start with audience and outcome

Who is watching, and what should they do after? Book a demo? Start a trial? Write that outcome down before a single line of voiceover.

Use a simple story spine

1. Who — the viewer (or a character standing in for them)
2. What — the pain or friction
3. How — your product or service solving it
4. Why you — differentiation without a feature dump
5. CTA — one clear next step

Clarity in the opening seconds; a finish that does not fizzle.

Keep the voiceover human

Speak like a smart colleague, not a press release. Cut jargon unless your audience lives in it. Read the script aloud; if you trip, rewrite.

End with a call to action

1. Kick-off — Product, audience, goals, brand and constraints.
2. Script — Problem, solution, proof points, CTA. You sign off.
3. Storyboard and style — Keyframes and look direction before it moves.
4. Voiceover — Cast and record against the locked script.
5. Animation — Boards to life, timed to VO and music.
6. Delivery — Final review, agreed tweaks, files for web, social and sales — including captions when scoped.

You stay in the loop at each major gate. That is how we avoid discovering a wrong tone after weeks of animation.

What does an explainer video cost?

Studio projects commonly sit in the $6,000 to $35,000 and beyond band — length, style, custom assets, revisions, VO and timelines. Whiteboard and straightforward 2D tend to sit lower than custom 3D or medical; templates and DIY sit outside it.
