A 30-second explainer video script fits in about 75 words: what a voice-over reads at a natural pace. For a SaaS, those words first set up a problem, then show the product that solves it.
Here is the five-sentence template to copy, a filled-in example, and the mistakes that blow past the stopwatch.
Why scripts run long
The first draft of a 30 second script is often 150 words. You want to say everything: every feature, every integration, the pricing, the company story. The voice speeds up to fit it all, viewers drop off, and the video ends up at 50 seconds.
In a studio, that overrun costs money: each extra 30 seconds adds roughly a third to the bill. With any tool, it costs attention, which is worse.
The five-sentence template
Fill in the brackets, without adding a sentence:
- The hook: “Still [concrete problem your customer lives every week]?”
- The cost of the problem: “Every [week or customer], that's [what it costs them].”
- The product: “[Product name] [does what] in [how long or how many steps].”
- The proof: “[A true number, or a customer with their agreement].”
- The action: “[Try it or book a demo] at [your address].”
Five sentences of 12 to 16 words make about 70 words. That leaves a little room to breathe, and for the music to be heard.
A filled-in example
For an imaginary invoice reminder tool, called Chaser here:
- “Still chasing unpaid invoices by hand?”
- “Every forgotten reminder is cash sitting idle.”
- “Chaser follows up with your customers for you, at the right time and in the right tone.”
- “It connects to your invoicing software in two minutes.”
- “Try it free today.”
This script is about fifty words, around twenty seconds read aloud. The remaining time is for showing the interface without talking over it.
Writing for the ear
- Short sentences. One sentence, one idea.
- One number per sentence, rounded if needed: people remember “two hours”, not “1 h 57”.
- Action verbs rather than nouns: “follows up” rather than “reminder management”.
- Your brand name spelled the way it is pronounced, if the voice might mangle it.
- A read-through aloud with a stopwatch, before producing anything.
Let the image do the talking
The script does not describe what is on screen. If the screen shows the dashboard, the voice says what it brings. On-screen text repeats the key words of the voice, for people watching without sound.
The first sentence matters more than all the others: it is the hook, and it deserves several drafts. Six ways to write it are in our article on the video ad hook. For what comes next, from voice to publishing, see our launch video guide.

Frequently asked questions
How many words for a 60 second video?
About 140 to 160 words at a natural pace. Fewer is better than more: pauses leave room for the image and the music.
Should you write the script yourself?
You know your customer better than anyone, so yes for the message. Shaping it and counting the words can be handed to a copywriter or to software.
Script in English or French?
In the language of your first market. If you target both, write two scripts rather than a word-for-word translation: hooks do not always translate.
How do you check a script's length?
Read it aloud, at a conversational pace, with a stopwatch. If it runs over, cut a whole sentence rather than speeding up.
In short
A good 30-second explainer video script fits in five sentences and about 75 words. A hook, a problem, the product, a proof and an action: the image shows the rest better than words can.
