How to Script an Explainer Video: The Brief Template Agencies Actually Use

Most explainer videos are bad because of decisions made before a single frame was designed.

The script is where explainer videos live or die. A weak brief leads to a weak script. A weak script leads to rounds of revision, scope creep, and an end product that kind of explains your product but doesn't really sell it.

The good news: how to script an explainer video is actually a learnable process. There's a structure to it. Agencies have templates. And once you understand the framework, you'll stop wasting time (and money) on production that doesn't perform.

Here's the brief template that actually works.

Why Briefs Fail (and Why It Matters)

When a brief goes wrong, it's almost always because of one of three problems:

Too much product, not enough story. The client lists every feature and asks for all of them to be in the video. The result is a script that reads like a press release and a video that nobody watches past 30 seconds.

Unclear audience. "Our target audience is companies who need our solution." That's not a brief. That's a non-answer. The more specific you are about who is watching, what they already believe, and what you want them to feel, the better the script will be.

No single core message. If you can't answer "what's the one thing this video should make the viewer do or believe?" in one sentence, the script can't answer it either. Briefs that try to accomplish five things accomplish none of them.

A good brief forces you to make these decisions before production. That's the point. It's harder upfront and much easier throughout.

The Explainer Video Brief Template

Use this as your starting document. Fill in each section before you write a single word of script.

1. Product / Service Overview (3–5 sentences)

What does it do? Who does it serve? What's the core value proposition? This isn't the script. It's context for the writer. Write it the way you'd explain it to a smart friend who's never heard of your company.

2. The Problem It Solves

Describe the pain your audience experiences before they find your product. Be specific. "Their spreadsheets are a mess and nothing integrates" beats "they have inefficient processes." The problem statement is often the opening hook of the video — so the more vivid, the better.

3. Target Audience

Who is watching this video? Include: role/title, company type/size, what they already know about your category, and what they're skeptical about. Anticipate their objections. A script written for a first-time founder is very different from one written for a VP at an enterprise company.

4. Core Message (one sentence)

This is the single thing the viewer should walk away believing. Not three things. One. If you can't write it as a single sentence, keep cutting until you can.

Example: "With [Product], any team can automate their reporting workflow in under an hour — no code required."

5. Key Points (3 maximum)

If your core message is the thesis, these are your supporting arguments. Three is the maximum. Every key point should support the core message — not introduce a new one.

6. Call to Action

What should the viewer do immediately after watching? Sign up for a free trial? Book a demo? Visit a landing page? Be specific about both the action and where it points.

7. Tone and Style

Describe the feeling you want the video to create. Choose 3–5 adjectives. "Professional, clear, reassuring" is a different brief than "energetic, bold, irreverent." If there are brand voice guidelines, attach them.

8. Format / Length Target

How long should it be? Research consistently shows that 60–90 seconds is the sweet spot for most SaaS explainer videos — that's roughly 150–225 words of script at a natural speaking pace. If you want two minutes, you need to justify it with genuinely complex content.

9. Reference Videos

Link 2–3 examples of videos you like. Don't just say "like this one" — note specifically what you like about each. The animation style? The pacing? The tone? The way it explains the problem? Designers need to know what you're responding to.

The Script Structure That Works

Once the brief is locked, the script follows a proven structure. The most reliable framework for explainer video scripts is PAS: Problem, Agitation, Solution. There are variations, but this is the skeleton.

Hook (first 5–8 seconds): Open on the problem, not the product. Your viewer doesn't care about your company yet. They care about whether this video is relevant to their life. Lead with a pain point they recognize.

Problem expansion (8–15 seconds): Make the problem feel real. Don't just name it — show its consequences. What does it cost them? What does their day look like because of it? This is where agitation happens. You're not twisting the knife; you're creating resonance.

Solution introduction (10–15 seconds): Introduce your product as the answer to the problem you just named. Don't list features yet. Name the outcome first. "Now there's a better way" is a structural move that earns attention for what comes next.

How it works (20–30 seconds): This is where you explain the product — but through outcomes, not features. "You upload your data, the system processes it overnight, and you wake up to a clean report" is better than "our platform has automated data processing and customizable reports."

Social proof or credibility signal (5–10 seconds, optional): A statistic, a customer result, or a simple claim that builds trust. "Trusted by 2,000 teams" or "customers save eight hours a week on average." Keep it tight.

Call to action (5 seconds): Direct, specific, single. End clean.

A note on word count

At a natural narration pace of about 150 words per minute, a 60-second video is roughly 150 words. A 90-second video is around 225 words. Write lean. Read it aloud and time it — most first drafts run long.

Production example: animated illustrations in context

Handing Off to an Animation Team

Once the script is final — truly final, not "mostly final, we might change a few things" — the brief should also include:

Visual direction notes. Which parts of the script need visual illustration versus UI screen recording? Are there metaphors in the script that need conceptual design? Flag these specifically.

Brand assets. Logos, color palette, typography rules, any existing visual assets that should influence the animation style.

Music direction. Describe the energy: "upbeat but focused, like a productivity app" or "calm, reassuring, like a financial tool." Music direction is underrated — the wrong track kills an otherwise good video.

Approval process. Who needs to sign off at each stage? Storyboard, animatic (rough motion), final? Clarify this upfront. The biggest production delays come from undefined approval chains.

With Jamm, this handoff is clean by design. You submit your brief, your script, and your reference assets. Jamm works through one deliverable at a time — you see the first stage, give feedback, and the next begins only once you're satisfied. No big reveals. No "we made the whole thing, here's your one round of revisions."

Common Script Mistakes to Avoid

Starting with "we." "We're [Company] and we help companies..." Nobody cares yet. Start with their problem, not your elevator pitch.

Using internal jargon. If you use a term your audience would need to Google, replace it. Scripts should read like conversation, not whitepapers.

Burying the CTA. A lot of scripts build slowly and only reveal the call to action in the last five seconds. By then, some percentage of your audience has already moved on. Allude to the CTA early ("and by the end of this, you'll know exactly how to get started") so viewers know there's something actionable coming.

Writing for the reader, not the listener. Scripts are heard, not read. Complex sentence structures, nested clauses, and long paragraphs don't translate to audio. Write in short, direct sentences. Read everything aloud.

The Brief Is the Product

The best animation studios will tell you: the quality of the final video is almost entirely determined by the quality of the brief and script. Production skill matters, but it's applied to what you give them. Garbage in, garbage out.

Spending an extra two hours on your brief before production starts is the highest-leverage move you can make on an explainer video. It saves revision rounds, it focuses the creative team, and it dramatically increases the odds that what gets made actually converts.

Start your design subscription and bring your brief to a team that knows what to do with it.
