Every subject matter expert’s first draft is a document. It reads well, it’s accurate, legal approved it — and it falls apart the moment someone says it out loud. Here’s the tell. Open that draft and read the opening paragraph. It almost always explains who the organization is and when it was founded. The real first line of the video — the one a viewer would stay for — is usually sitting in paragraph three.
That isn’t a failure of intelligence. It’s a failure of format. A reader can go back a sentence. A listener can’t. Nearly every rule below follows from that constraint. The useful news is that how to write a video script is a learnable skill with a short list of rules, most of them mechanical. You don’t need to be a writer. You need to know what breaks when someone reads your words into a microphone.
Write for the Ear, Not the Page:
Most video script writing problems trace to one habit: writing sentences built to be scanned. Read the draft aloud and they surface. Run out of breath and the sentence is too long; stumble and the structure is wrong. Federal plain-language guidance, now at digital.gov, is the best free style guide here: one idea per sentence, everyday words, “you” not “the user.” Active voice does the most work — passive construction buries who does what, and a listener can’t back up to work it out.
Write numbers the way they’re said, too. A narrator reads what’s on the page, so “22%” earns a retake and “twenty-two percent” doesn’t. Technical content raises the bar. NIH and the AMA put patient materials near a sixth-grade reading level; CDC guidance says eighth. Narration for healthcare video production should meet the same standard as the printed handout.
Structure That Survives Review:
The three parts
- Hook, first ten seconds. The viewer’s problem, not the organization’s mission.
- Core. One idea per section, ordered the way someone would ask, not the way the org chart runs.
- Call to action, last ten seconds. One action, plainly. Not three options and a QR code.
Where that advice misleads
Hook writing assumes the viewer can leave. In mandatory training and compliance, they can’t. A captive audience doesn’t need grabbing — it needs telling, immediately, why this video applies to this person. Bolt a marketing hook onto a compliance module and you’re selling something people already have to watch.
Do the Math Before You Write
The National Center for Voice and Speech puts average conversational speech for U.S. English speakers at about 150 words per minute. Budget lower for narration — roughly 130 — because pauses, breaths, and moments carried by the picture eat time. That’s your budget before you write a word: 130 words for sixty seconds, 195 for ninety, 260 for two minutes. Hand in 400 for a ninety-second piece and something gets cut — usually what you cared about most.

Four Things That Break a Script in Production:
- Over-explaining. Experts write down everything true. A script needs only what the viewer must hear.
- No visual direction. If the script never says what’s on screen, an editor decides for you. Note the shot beside the line.
- Wall-to-wall narration. No gaps leaves nowhere for music, ambience, or audio description; fixing it later means re-cutting.
- Stage directions in the narration. “As you can see on screen” dies when the edit changes. Put it in the visual column.
Should You Write It Yourself?
Write your own draft when the content is short, simple, and yours — a message from your director sounds better in their own words. Hand it over when the material is technical, when structure carries the meaning, or when several people sign off. The division that works: you own accuracy, the production team owns structure and rhythm. Projects die on the reverse — an expert editing a writer’s draft back into a document.
The two-column script settles most arguments. Audio one side, visuals the other. If you can’t fill the visual column beside a line, that line belongs in a PDF. Training teams comparing educational video companies usually find scripting folded into pre-production.
Frequently Asked Questions:
Q1. How long should a script be for a two-minute video?
About 260 words of narration. Word count is an estimate; a stopwatch is not.
Q2. Who should review the script, and when?
Everyone with the power to say no, once, at the script stage. Reviewers who arrive at the rough cut cost real money.
Q3. Does everyone on camera need a script?
No. Script the narration; for interviews, write the questions instead. Answers drafted in advance sound drafted in advance.
Final Thoughts:
Good video script writing isn’t literary. It’s structural — what a listener absorbs, what a camera shows, how much of either fits in ninety seconds. Get it right and production becomes execution; get it wrong and every later stage pays. Before you send your next draft to a production partner, read it aloud against a stopwatch. If it runs long on the page, it will run long on screen.
