By the time most businesses start thinking about an explainer video, the decision to use video has already been made.
The harder question comes next: what actually needs to go into it?
That’s where many explainer videos lose their way. Too much detail, unclear structure, or a message that tries to do everything at once can leave viewers more confused than when they started.
This guide focuses on the essentials – what an explainer video should include, why each element matters, and how to make sure everything works together to create clarity rather than noise.
🔑 Key Takeaways
- Great explainer videos are planned, not improvised.
- The script matters more than production polish.
- Visuals should clarify ideas, not decorate them.
- Structure and pacing determine whether viewers stay engaged.
- A clear call-to-action turns understanding into momentum.
- Explainers work best when they’re part of a wider content strategy.

What an Explainer Video Is Actually For
Before deciding what to include, it’s worth being clear about what an explainer video is meant to do.
An explainer video exists to create understanding. Its role is to help someone grasp what something is, why it matters, and how it fits into their world – without overwhelming them with detail.
It isn’t a training video. It isn’t a sales pitch. And it isn’t a product manual.
Once that purpose is clear, every decision about content becomes easier.
The Script: What It Must Include
The script is the foundation of any successful explainer video. Strong visuals can’t rescue a weak or unfocused message.
A good explainer script typically includes:
- A clear problem or challenge the viewer recognises
- A simple explanation of the concept, product, or service
- A logical flow from problem to resolution
- Plain, conversational language without jargon
- One core message, not a list of features
If you’re weighing up production budgets, it’s worth noting that script development is one of the biggest factors influencing quality and cost. Our guide to explainer video production cost factors breaks down where time – and money – is usually spent.
Visuals That Support Understanding
Visuals in an explainer video should exist to clarify ideas, not to impress for the sake of it.
The most effective visuals:
- Translate abstract ideas into simple metaphors
- Reinforce key points as they’re spoken
- Stay visually consistent from start to finish
- Avoid unnecessary motion or detail
Animation is often used because it allows complex or intangible concepts to be visualised clearly, but live-action can work just as well when real-world context adds value.
Structure & Length: How Information Should Flow
Explainer videos work best when information is introduced in a logical, viewer-friendly order.
Rather than dumping everything at once, high-performing explainers follow a predictable structure:
| Section | Purpose | What the Viewer Is Thinking |
|---|---|---|
| Problem | Create relevance | “Yes – that’s my issue.” |
| Concept | Introduce the idea | “I see how this fits.” |
| Value | Explain benefits | “This could help me.” |
| Next Step | Guide action | “What should I do now?” |
This structure keeps viewers oriented and prevents cognitive overload, even in short videos.
Voice, Pacing & Delivery
How something is said often matters as much as what’s being said.
Effective explainer videos use:
- A calm, confident voice
- Natural pacing that allows ideas to land
- Pauses where information needs processing
Overly fast delivery or exaggerated tone can undermine trust, especially when explaining complex or high-stakes topics.
The Call-to-Action
A strong explainer video always gives the viewer a clear next step.
That doesn’t mean a hard sell. It means guidance.
Good explainer CTAs might invite viewers to:
- Learn more about a service
- Book a conversation
- Watch a follow-up video
- Explore a solution in more detail
This is where professionally planned explainer videos consistently outperform DIY attempts – because the CTA is aligned with the viewer’s stage of understanding.
What Not to Include in an Explainer Video
Some of the most common explainer video mistakes come from trying to include too much.
- Feature lists without context
- Internal jargon or acronyms
- Multiple competing messages
- Humour that distracts from clarity
When in doubt, simplify. One clear idea beats five half-explained ones.
Final Thoughts
Explainer videos work when every element serves the same goal: helping the viewer understand.
The strongest explainers combine a focused script, purposeful visuals, clear structure, and a well-judged call-to-action. They don’t try to do everything at once – they do one thing well.
For businesses introducing complex ideas, services, or products, an explainer video is often the most effective place to start. That process works best when it’s part of a wider content strategy – something an experienced video marketing company can help shape from concept through to delivery.
