Storyboard a PSA video and script voiceovers

A Public Service Announcement (PSA) is a short video designed to inform the public and persuade them to change a behavior or take action on an important issue. Before any filming or animation begins, creators plan every scene on a storyboard — a series of panels that show what the audience will see and hear in each moment.

What Is a Storyboard?

A storyboard is a visual script. Each panel represents one scene or shot and contains four key elements that work together to communicate the message.

• Visual description — what the viewer sees on screen (setting, characters, action, camera angle).
• Voiceover text — the words spoken aloud by a narrator or character that the viewer hears.
• On-screen text — captions, statistics, slogans, or titles that appear as text overlaid on the video.
• Duration — the approximate number of seconds the scene lasts.

The Four-Stage PSA Structure

1. Hook — grabs attention in the first 3–5 seconds with a startling fact, question, or striking image.
2. Problem — clearly states the issue and why it matters, using evidence or an emotional appeal.
3. Solution — presents a specific action or change that the audience can make to address the problem.
4. Call to Action — ends with a direct, memorable instruction: visit a website, sign up, act now.

Writing Effective Voiceovers

• Be concise — a 30-second PSA holds about 70 spoken words. Every word must earn its place.
• Use imperative verbs — "Reduce", "Act", "Choose", "Help" — to drive action.
• Vary sentence length — a short, punchy sentence after a longer one creates emphasis.
• Match tone to topic — serious issues need a calm, urgent tone; awareness campaigns may use warmth.
