How To Write An Explainer Video Script That Actually Works

Most explainer video scripts fail for the same reason: they start with the product instead of the problem. The viewer doesn't care about your features yet. They care about their own frustration. Your script needs to meet them there first.

After writing and producing over 50 explainer videos, I've landed on a framework that consistently works, whether the video is 30 seconds for social or two minutes for a product walkthrough.

The Four-Part Framework

Every effective explainer video script follows this structure. The proportions shift depending on length, but the sequence stays the same.

1. The Problem (20% of your runtime)

Open with something your viewer already feels. Not a statistic. A situation. If you're making a SaaS explainer video, describe the specific workflow that's broken. If it's a cause video, describe the reality your audience hasn't seen.

For a 60-second video, this is about two to three sentences. You're not dwelling here. You're establishing recognition. The viewer should think "yes, that's exactly my problem" within the first ten seconds.

2. The Solution (10% of your runtime)

Introduce your product or organisation as the answer. Keep it to one sentence. Name it, say what it does at the highest level, and move on. The detail comes next.

3. How It Works (50% of your runtime)

This is where most of your screen time goes. Walk through two to four key steps or features that show how the product solves the problem you opened with. Each step should be visual. This is where your animator brings the interface or concept to life.

The most common mistake here is trying to cover everything. You don't need to show every feature. Pick the ones that matter most to your primary audience and show those clearly. Three features explained well beat eight features mentioned in passing.

4. The Call to Action (20% of your runtime)

End with what you want the viewer to do next. Sign up, book a demo, visit the website, learn more. Be specific. Add a line of social proof if you have it: a recognisable client name or a concrete result.

Word Count Guidelines

A professional voiceover reads at about 140 to 150 words per minute. Use that to calibrate your script length:

• 30-second video: 65 to 75 words
• 60-second video: 130 to 150 words
• 90-second video: 200 to 225 words
• 2-minute video: 270 to 300 words

If your script is running long, cut features, not the problem statement or the call to action. Those bookends are what make the video work.

Writing for Animation

Writing an explainer video script is different from writing a blog post or a sales page. You're writing for two audiences at once: the viewer who hears the words, and the animator who needs to visualise them.

• Write in scenes, not paragraphs. Each sentence or pair of sentences should correspond to a distinct visual moment. If you can't picture what's on screen while you read a line, rewrite it.
• Cut the jargon. If your target viewer wouldn't use a term in casual conversation, replace it. Technical accuracy matters less than immediate understanding.
• Read it aloud. Every script should sound natural when spoken. If a sentence feels awkward to say, it'll sound worse with a voiceover.
• Leave room for the visuals. The animation will carry a lot of meaning. You don't need to describe everything in words. Sometimes a pause with the right visual does more than another sentence.

Common Mistakes

• Starting with your company name and mission statement. Nobody cares yet. Lead with their problem.
• Listing features without context. "We offer real-time analytics" means nothing. "See which campaigns are working before your budget runs out" means everything.
• Making it too long. If you're over 90 seconds, you need a very good reason. Most products can be explained in 60.
• Writing the script after the design. Script comes first. The visual language should serve the story, not the other way around.

What Happens Next

Once the script is locked, it becomes the foundation for everything: storyboarding, style frames, animation, and voiceover. A strong script makes every stage faster and cheaper. A weak one creates expensive revisions.

If you'd rather have someone handle the script and production together, that's how I work. Every project at Motion Story starts with the script, and I don't move to design until the words are right. See how the process works or get in touch to talk through your project.
