How to write an explainer video script that makes sense

Start with one person, one problem

A script is easier to write when you know who is listening. “Business owners” is a broad audience. “A shop owner who spends every evening answering the same delivery questions” gives you something concrete to work with.

Write down what that person needs to understand and what they already know. Then choose one outcome for the video. It might be to explain a product, introduce a service, or help someone complete a task. Trying to do all three usually makes the story harder to follow.

Find the sentence that holds the story together

Before writing a voice-over, finish this sentence: “After watching, I want someone to understand that…” Keep your answer specific enough to explain without a list of qualifications.

For an order-tracking tool, the core message might be: “Your customers can see where their delivery is without calling your shop.” That sentence tells you which feature matters, who it helps, and which problem the video should show.

Keep this message beside your draft. When a scene feels interesting but does not help explain it, save that scene for another piece of content.

Build a simple four-part structure

1. The situation: show a moment your audience recognises.
2. The problem: explain what makes that moment frustrating or difficult.
3. The solution: show how your product or idea changes the experience.
4. The next step: invite the viewer to do one useful thing.

You do not need a dramatic opening for every story. A familiar question can work just as well. “Where is my order?” gets to the point because it names the problem in the audience’s language.

Write for the ear, then plan for the screen

Read every line aloud. If you need to stop halfway through a sentence to work out what it means, simplify it. Use the words your customers use rather than internal product terminology.

Put your script into two columns: voice-over and visuals. The voice-over carries the explanation; the visuals can show the steps, relationships, or changes. You do not need to repeat every spoken sentence as text on screen.

This is an illustrative example, not a claim about a particular product. The point is to give the voice-over and visuals different jobs.

Test the pacing before animation starts

Time a natural read of the script, leaving room for a viewer to look at what is happening. A technically short voice-over can still feel rushed when a scene contains a detailed interface or a multi-step process.

Ask someone unfamiliar with the product to read the draft. Can they tell you what it does, who it helps, and what they should do next? Their questions are more useful than a sentence that only sounds polished to the team who wrote it.

Finish with one useful next step

Match your call to action to the story. A product introduction might lead to a demo. A tutorial might send someone back to the task. A service explainer might invite a project enquiry.

For the brief you send your animation studio, include the audience, core message, intended platform, approximate length, and next step. You can explore our animation process to see how a script becomes a finished video.
