What Is an Explainer Video?
An explainer video is a short animated film — usually 30 to 90 seconds — that makes a product, service, or idea easy to understand. It is not a product demo, a brand anthem, or a recorded webinar. It is a scripted story with animation, voiceover, and one job: get a first-time viewer to understand the offer and know what to do next. Style (2D, whiteboard, product UI) is how that job looks. The script is the product.

What an explainer video is for
An explainer video has one job: get a stranger to understand the offer and know what to do next. It is built for landing pages, sales follow-ups, and product launches — not for brand mood or a full feature tour.
The viewer is usually cold. They have not been on a demo. They will not read a twelve-bullet feature list. In Wyzowl’s 2026 video survey (266 marketers and consumers), 96% of people had watched an explainer to learn about a product or service, and 63% said they would most like to learn via a short video — ahead of text, decks, and calls.
That is why the format exists. A good explainer compresses a sales conversation into a film someone can watch without a meeting: the problem, the change, the proof, and one ask. Put it on the page where the decision already happens. Do not hide it in a resource library nobody opens.
We produce these films as an on-demand studio — script, direction, animation, voiceover, music, and revisions — and most of them deliver within 3 days once the brief is clear. The format is old. The constraint is the same as it always was: say one thing well.
Explainer video vs product demo vs brand film
An explainer tells the story of the problem and the outcome. A product demo shows the interface doing the work. A brand film sells feeling. Most companies need the first; some also need the second. Almost none need a brand anthem first.
Teams mix these up because they all look like “a video.” They are different jobs:
| Film | Job | Where it lives |
|---|---|---|
| Explainer | Who it is for, what is broken, what changes, what to do next | Homepage, ads, outbound |
| Product demo | The product in use — proof, not origin story | Feature pages, sales follow-up, “see it in action” |
| Brand film | Tone, culture, category presence | Later. Expensive as a first hire |
A SaaS homepage that opens on a raw screen recording often asks a stranger to care about a UI they do not understand yet. A demo that tries to also be an origin story usually finishes neither. If you can only make one film this quarter, make the explainer. Add the demo when people are already considering a trial.
Types of explainer videos
The common production styles are 2D character or UI animation, whiteboard, kinetic type, and short product explainers. The style should follow the audience and the claim — not a trend on someone else’s homepage.
Style is not the strategy. It is how the strategy looks. The styles we actually produce:
- 2D explainer — characters, diagrams, product UI on a flat plane. The default because it reads on a phone and revises without rebuilding a 3D scene.
- Product / UI explainer — the interface is the proof. Right when the product is the story, as with a legal-tech workflow or a credential feature launch.
- Whiteboard — drawing the idea in real time. Strong for education and process. Weak when you are selling a premium product that needs to look like itself.
- Training explainer — still animated, but the viewer already has a reason to watch. The job is followable steps, not a campaign hook.
Corporate Memphis, collage, kinetic type, and 3D are tools in that same kit. We pick them after the script is true, not before.
How long an explainer video should be
Most of the films we produce land in 30–90 seconds. Long enough to set up the problem, show the change, and ask for one action. Past two minutes, completion drops and the script usually has two videos hiding in it.
Spoken English is roughly 130–150 words a minute. A 60-second explainer is a 130–150 word script. If the draft is 400 words, you do not have a “pacing” problem. You have two messages. Wyzowl’s 2026 survey found 71% of marketers say videos between 30 seconds and 2 minutes are most effective — the same working range we use, tightened to 30–90 seconds for a single claim.
Short (20–30 seconds) works for a single feature or a retargeting cutdown. Long (90–120 seconds) works when the buyer needs a little more mechanism — research context, a regulated product, a non-obvious category. Past that, split the film. One for the homepage. One for people who already want the details.
What goes into a good explainer video
A usable explainer is a script, a visual system, animation, voiceover, and sound — directed as one piece. Skipping the script or treating animation as decoration is how videos look expensive and still fail to convert.
The production sequence that actually holds:
- Brief — audience, the page the film will live on, the one action.
- Script — approved before anyone draws. This is the product.
- Direction — style, UI accuracy, voice, what the picture must show that the voiceover will not say.
- Animation, voice, mix — then revisions for accuracy and tone.
- Delivery — the formats the page, ads, and sales team will actually use. You own the film.
We use modern tools for speed. Humans still direct and finish every video. An AI-only pass is fast in the way a first draft is fast: it is not the film you should put on a homepage.
Explainer video examples
The fastest way to understand the format is to watch real films: a timeline story, a product walkthrough, a feature launch, and a training piece. Length and style change; the job does not.
These are films we made — not a moodboard of other studios. The players below are the real files.
| Client | Length | Job |
|---|---|---|
| BERA | 1:48 | Research anniversary as an animated timeline |
| Jude | 1:48 | Legal-tech workflow from prompt to document |
| AccessGrid | 0:31 | One feature launch — credential pools |
| PS Fertility | 1:21 | Patient education / training explainer |
BERA · 1:4850 Years of ResearchAnniversary film for the British Educational Research Association — a 50-year story told as an animated timeline. Jude · 1:48Conference explainerA full product story that walks a legal-tech workflow from prompt to finished document.

BERA is a research story told as a timeline. Jude is a product workflow from prompt to document. AccessGrid is a 31-second feature launch. PS Fertility is patient education — closer to training than a campaign, and still an explainer in the useful sense: a complicated thing, made followable.
When a business actually needs one
You need an explainer when the offer takes too long to explain on a call, when the landing page bounce is the sales problem, or when a new product has to make sense in under a minute. You do not need one to “have video.”
Signals that the format is the right hire:
- Sales repeats the same five-minute preamble on every call.
- The homepage is a wall of features and a weak conversion, not a traffic problem.
- A launch or new category has to make sense to people who will not sit a demo.
- A process or product is losing people in a PDF or a help center nobody finishes.
If you already have a film and nobody can say what it is asking the viewer to do, you do not need a restyle. You need a new script.

Frequently asked questions
What is an explainer video in simple terms?
- A short animated film — usually 30 to 90 seconds — that explains a product, service, or idea so a first-time viewer understands it and knows what to do next. Script, animation, and voiceover work as one piece.
Is an explainer video the same as a product demo?
- No. An explainer covers the problem, the change, and the outcome. A product demo shows the product being used. Many SaaS teams need both: the explainer for the homepage, the demo for people already considering a trial.
How long should an explainer video be?
- Most of ours land in 30–90 seconds. That is long enough to explain the idea and short enough that people watch to the end. If the script runs past two minutes, it is usually two videos.
Do explainer videos still work in 2026?
- They work when the script is specific and the film sits where a decision happens — a landing page, a sales email, a launch. A generic “we are innovative” cartoon does not. The format is not the tactic; the message is.
