How to Script a Thirty-Second Video

Businesses freeze at filming because they think a script means paragraphs. A thirty-second video needs four sentences and a decision about what to leave out.

Writing a short script out on a whiteboard

The four-line frame

Hook, problem, proof, ask. One sentence each, written before you touch the camera. If a line does not fit one of the four, it does not belong in this video.

Write the ask first

Decide what you want the viewer to do, then work backwards. A video written without a destination becomes an announcement, and announcements do not convert.

  • One ask only: message, visit, save, or call.
  • Say it once, at the end, plainly.
  • Put it on screen as well as in the audio.
  • Never stack two asks in the same video.

Say it out loud before you record

Read the four lines twice. Anything you stumble on is written, not spoken, so change it. This is the whole difference between sounding like a person and sounding like a brochure.

Keep the offcuts

One shoot with four scripts gives you four videos, and the lines you cut usually become the next one. Keep a running list of the sentences you deleted.

Real examples

Bad line, good line.

Most people write

A page of notes read off-camera in a monotone.

Say this instead

Four lines: hook, problem, proof, ask. Nothing else written down.

Most people write

Two asks in one video: follow us and visit us.

Say this instead

One ask, said once, on screen and out loud.

Full example

Worked example: a thirty-second script

01Ask first: "message us to hold one." Now write backwards from it.
02Hook: "These sell out every week." Problem: "People message when they are gone."
03Proof: six seconds of the shelf and the stock count. Then the ask, once.
Thirty seconds

Hook

One claim, first second.

Problem

The reason they should care.

Proof

Show it, do not describe it.

Ask

One next step, once.

Written in this order, filmed in the other: the ask is decided first.

A script is not a paragraph. It is four sentences and the courage to delete the fifth.

Do this week

Three things you can do now.

01Write four videos as four lines each in one sitting.
02Decide the single ask before you write the hook.
03Read every script aloud and rewrite whatever you stumble on.
