Writing an explainer video script usually means leaving good information out. In 60 or 90 seconds, there is rarely room for every feature, proof point, use case, and company detail. The writer has to decide what the viewer needs first and what can wait.
At Yum Yum Videos, we have written scripts for more than 1,000 animated videos. One production problem comes up again and again: companies know their products in far more detail than a first-time viewer does. A good explainer video script closes that gap without turning into a product manual.
This guide covers the structure we use, a copyable explainer video script template, word counts by video length, a sample script, and three real projects from our own work.
Table of Contents
An explainer video script is the working document that organizes the spoken message and the visual action of an explainer video.
The voiceover tells the audience what they need to know. The visual notes describe what should happen on screen while those words are being spoken. Those two parts should work together. If the narration says exactly what the animation already shows, the video wastes time.
A script normally answers a few basic questions:
That sounds simple. The difficult part is deciding what does not belong in the script.
For a standard product or service explainer, this is the structure we use most often as a starting point.
Voiceover
[Describe the problem in the language your audience would actually use.]
[Show what that problem costs them in time, money, effort, risk, or frustration.]
Visual
Show a recognizable situation. Keep the brand in the background for now.
Voiceover
[Introduce your product or service.]
[Explain the core value proposition in one sentence.]
Visual
Bring the product into the story. This may be a character interaction, a simplified interface, a diagram, or a visual metaphor.
Voiceover
[Explain the first important step.]
[Explain the second important step.]
[Connect those steps to the outcome the customer cares about.]
Visual
Use the screen to show information the narration cannot communicate as efficiently. A workflow can move across the frame. Data can travel through a system. A before-and-after state can change visually.
Voiceover
[Add one relevant proof point.]
This can be a customer result, an adoption figure, a recognizable client, a short testimonial, or a concrete product capability.
Visual
Keep the proof easy to read. One credible point is stronger than a wall of logos or numbers.
Voiceover
[State one action you want the viewer to take.]
Visual
Show the URL, button, QR code, product screen, or next step that matches the voiceover.
That is the template. It should bend when the story requires it. Some videos need a longer problem section. A product demo may move into the interface much earlier. A brand video may spend almost no time explaining features.
For most explainer video scripts, we estimate around 150 to 160 spoken words per minute for a clear commercial voiceover. A slower subject needs fewer words. A fast, energetic piece can fit a little more.
| Video length | Approximate script length |
|---|---|
| 30 seconds | 75 to 80 words |
| 60 seconds | 150 to 160 words |
| 90 seconds | 225 to 240 words |
| 2 minutes | 300 to 320 words |
A 90-second script with 400 words is not a 90-second script. Reading it faster rarely fixes the problem. The copy needs to be cut.
For more on runtime, see our explainer video length guide. The easiest test is to read the script aloud at the pace you want the voice actor to use. Time it. Pauses, product names, numbers, and technical terms often take longer to say than they look on the page.
For scriptwriting for explainer videos, the hardest part is usually deciding what to leave out before the first draft gets too long.
Start with one sentence:
After watching this video, the viewer should understand that ________.
That sentence forces a decision about the video’s main job.
A homepage explainer may need to answer “What does this company do?” A product launch video may need to explain one new capability. A sales video may need to make a complex workflow easier to discuss in a meeting.
If the answer contains five different objectives, the script is already carrying too much.
A script for a CFO should not sound like a script for a new user learning an app.
You do not need a fictional biography with a favorite coffee shop and a made-up dog. You need the details that affect the script.
Ask:
Those answers influence the vocabulary, pace, proof, and amount of explanation in the video.
Many explainer scripts open with the company.
“We are X, a leading platform that…”
That makes the viewer do the work of figuring out why the product matters.
A stronger opening starts closer to the situation the customer already recognizes. For a billing platform, the problem may be revenue leakage or manual reconciliation. For a healthcare product, it may be a slow patient recruitment process. For a logistics platform, it may be disconnected systems.
Use the words customers use in sales calls, support tickets, onboarding sessions, and interviews whenever you have access to them.
The product should arrive at the moment the viewer is ready for it.
That does not mean every explainer needs 30 seconds of setup. Some audiences know the category already, so the solution can appear almost immediately. The important part is that the viewer understands what job the product is being asked to do.
Keep the first product description short.
A sentence such as:
“Acme brings your invoices, subscriptions, and payment data into one place.”
does more work than a paragraph of category language and feature names.
Features belong in an explainer video when they help the viewer understand the value.
“Automated reconciliation” is a feature.
“Your finance team stops matching transactions by hand” explains what changes for the customer.
You can still name the feature. Just connect it to the outcome.
A practical editing test is to read each feature sentence and ask, “So what?” The answer is often the line that belongs in the script.
An explainer video is not an illustrated podcast.
If the voiceover says, “Data moves from your CRM into your billing platform,” the visual can show that movement. The narration does not need another sentence explaining where the data goes.
Writing visual notes early also reveals weak sections. A paragraph that produces no visual ideas may be too abstract, repetitive, or unnecessary.
We often use comments while scripting to capture visual thoughts before the storyboard stage. They do not need to be polished. A note like “customer gets buried in spreadsheets” is enough to give the storyboard team a direction.
Written language can hide problems that spoken language exposes immediately.
A sentence may look short and still be awkward to say. A list of product names may slow the pacing. Two sentences may repeat the same idea with different wording.
Read the complete script aloud and mark every place where you naturally stumble, run out of breath, or want to shorten a phrase.
Then read it again with a timer.
An explainer video script does not need three competing next steps.
Choose the action that matches where the viewer will see the video.
A homepage video might end with Book a demo.
An onboarding video might use Create your first project.
A social campaign could direct viewers to Learn more.
The voiceover and visual CTA should point to the same action.
Here is a simple explainer script sample for a fictional workflow platform.
Voiceover
Your team approves purchase requests in email, tracks budgets in spreadsheets, and chases signatures across three different tools. By the time finance sees the final request, nobody is completely sure which version is current.
Visual
An employee jumps between an inbox, a spreadsheet, and a messaging app. Multiple document versions begin stacking up.
Voiceover
Flowdesk puts the entire approval process in one workspace, from the first request to the final sign-off.
Visual
The scattered windows collapse into one clean workflow.
Voiceover
Employees submit a request using a simple form. Flowdesk sends it to the right approver based on your rules and keeps the budget updated automatically. Finance can see the request, comments, documents, and approval history in one place.
Visual
Show the form, routing logic, budget update, and approval timeline as one continuous sequence.
Voiceover
Every decision stays attached to the request, so your team has a complete record when it is time to review spending.
Visual
Zoom out to show a clean approval history with dates and comments.
Voiceover
See how Flowdesk could fit your approval process. Book a demo.
Visual
Product logo, URL, and Book a Demo button.
The sample uses 129 spoken words. That leaves room for pauses, transitions, and an unhurried read inside a 90-second production.
MedVector helps connect patients with clinical trials. When we worked on the project, the communication challenge was explaining a healthcare process with several participants, delays, and decisions without turning the script into a technical description of clinical research.
We opened with the patient recruitment problem.
The visual concept turned the process into a board game. That gave the script a concrete world in which delays, obstacles, and progress could happen on screen.
The first part of the video stays focused on the problem before MedVector becomes the solution. That sequencing matters because the audience understands what is broken before they hear how the company addresses it.
MedVector later raised $3.5 million. We treat that as a company milestone, not as a result caused by the video. You can see more context in our MedVector case study. The project is useful here because the script had to make a complicated healthcare service understandable to patients, partners, and investors at an early stage of the company.
The Amazon Appstore project had a narrower job: explain how Windows 11 users could access Amazon’s app ecosystem on desktop.
That allowed the script to move quickly.
The product appears early, and the middle of the video walks through the basic process without turning into a long tutorial. The viewer only needs enough detail to understand what changed and why it matters.
We also used the character story to give the product demonstration a human context. A father and daughter end up playing together on a larger screen. The moment is short, but it gives the feature a reason to exist beyond the mechanics of installing an app.
For product integrations, that balance is valuable. Explain the new capability, then show what becomes possible because of it.
The Upgrade video runs for about a minute, so the script cannot spend long on setup.
The opening shows a young woman frustrated with her current checking account. Upgrade then enters as the answer to that situation, and the script moves through the relevant benefits, including no monthly fees and cashback.
The emotional shift follows the product story. Frustration at the beginning gives way to relief as the character discovers a better option.
This is a useful explainer video script example because the story does not require a complicated plot. One character, one recognizable problem, and one change in her situation are enough to give the product message a narrative shape.
The viewer usually needs the problem and value proposition before they need your history.
Move founding dates, mission statements, and broad company descriptions somewhere else unless they are directly relevant to the decision.
A short explainer cannot replace a product demo, help center, sales presentation, and onboarding sequence at the same time.
Pick the information required for this video’s job. Other details can live in other assets.
Animation needs room to communicate.
If every idea is already described twice in the narration, the screen has nothing new to add.
“Best,” “revolutionary,” “industry-leading,” and similar phrases take up valuable seconds without explaining why the viewer should believe them.
Use a specific capability, customer result, or concrete difference instead.
The final action should not make the viewer guess.
If you want a demo, say Book a demo. If the next step is to create an account, say that.
Before the script goes to storyboard, check the following:
That last question is worth asking twice.
An explainer video script is ready for storyboard when the message is clear enough that the visuals can do part of the explaining. If the voiceover still has to carry every detail by itself, cut or reorganize the copy before animation production begins.
