What Is an Explainer Video and When Does Your Business Actually Need One?
An explainer video is a short video, usually 30 to 90 seconds, that makes one product, service, or process easy to understand. It takes something that would be slow to read or awkward to describe and shows it clearly, often using simple visuals, a voiceover or captions, and a single focused message. If a new customer keeps asking the same question, or a new hire keeps getting stuck at the same step, that is the gap an explainer video fills.
The format is defined by its job, not its length or style. Some explainers are animated, some use screen recordings, some mix stock footage with on-screen text. What they share is a tight scope: one idea, explained start to finish, so the viewer walks away knowing how something works or why it matters.
What separates an explainer video from a promo or a demo?
The difference comes down to intent. An explainer video teaches. A promo video sells a feeling or an offer, and a product demo walks through features in detail. They overlap, but the goal changes what you put on screen.
An explainer answers "how does this work?" or "what is this for?" in the simplest terms. A promo video is built to create interest or urgency, often for a launch or a campaign. A product demo goes deeper, showing real screens and workflows for someone already considering a purchase. If you try to do all three in one video, none of them lands well.
| Video type | Main goal | Typical length | Best for |
|---|---|---|---|
| Explainer | Make one idea clear | 30 to 90 seconds | New product, complex process, onboarding |
| Promo | Create interest or urgency | 15 to 60 seconds | Launches, campaigns, social ads |
| Product demo | Show how features work | 1 to 5 minutes | Buyers comparing options |
| Announcement | Deliver news once, clearly | 30 to 90 seconds | Internal or company updates |
When does your business actually need one?
You need an explainer video when words alone keep failing. A few situations reliably call for one.
You are launching something new. When you introduce a product or feature people have never seen, a short explainer shortens the gap between "I don't get it" and "I want it." It gives sales, marketing, and support a single clear reference instead of ten different verbal pitches.
The process is genuinely complex. Sign-up flows, insurance choices, software setup, returns policies. If you find yourself writing long help articles that nobody reads, a video that shows the steps in order tends to work better. For operations and support teams, that can cut repeat questions, which is why many operations teams use short video to document how things get done.
You are onboarding people. New employees and new customers both face the same problem: too much to absorb at once. An explainer breaks the first steps into something watchable. HR and internal comms leads often build a small set of these so every hire gets the same clear start, which pairs well with how HR teams handle onboarding.
You probably do not need one for a simple message that a sentence covers, or for news that changes weekly. In those cases a written note or a quick team update video does the job with less effort.
How do you build an explainer video in the browser?
You do not need an animator or editing software. A browser-based tool with a template does most of the structural work, so you focus on the message. The practical path looks like this.
- Write one sentence first. State the single thing the viewer should understand by the end. If you cannot fit it in one sentence, your scope is too wide for one video.
- Script in plain steps. Break your idea into three to five beats: the problem, how your thing solves it, and what to do next. Keep each beat short.
- Start from a template. Pick a layout that matches your structure so you are editing scenes, not building from an empty timeline. A large library of ready-made video templates gives you a running start.
- Add your own words and visuals. Swap in your text, drop in stock footage or animations, and set the pacing so each point has room to breathe.
- Apply your brand. Logos, colors, and fonts from a brand kit keep the video looking like it belongs to you, especially when several people make videos.
If you would rather not start from scratch at all, an AI assistant can generate a first draft from a text prompt, which you then trim and adjust. Both routes live inside the same explainer video maker, so you can pick whichever gets you moving faster and refine from there.
What makes an explainer video actually clear?
Clarity is the whole point, so a few habits matter more than production polish. Keep to one idea. Lead with the problem your viewer already feels, not with your company history. Use captions, since most people watch without sound, especially on social feeds. Cut anything that does not move the viewer toward understanding.
Length is a discipline, not a target. If your explainer runs past two minutes, it has probably grown into a demo, and the two jobs deserve separate videos. Marketing teams often make a short explainer for the top of the funnel and a longer demo for later, a split that fits how marketing teams plan video across a campaign.
Frequently asked questions
How long should an explainer video be?
Aim for 30 to 90 seconds. That is long enough to explain one idea and short enough to hold attention. If you need longer, the topic is likely two videos, not one.
Do explainer videos have to be animated?
No. Animation suits abstract ideas and processes, but screen recordings, stock footage, and simple text-on-screen all work. Choose the style that shows your point most clearly, not the flashiest one.
Can I make an explainer video without design skills?
Yes. Starting from a template means the structure, pacing, and layout are already handled, so you edit text and swap visuals rather than design from a blank screen. An AI draft can take you even further before you customize.
How much does it cost to make one?
It varies widely. A browser tool with free and paid options lets you make explainer videos in-house for far less than hiring an agency. See the current plan options to compare what fits your team.
Where should I put an explainer video once it is made?
Match placement to the goal. Product explainers go on landing pages and in sales emails, process explainers live in help centers, and onboarding explainers fit inside your training or welcome flow. One video can serve several of these spots.
