Opus 5.5 video prompts
for real explainers.

Paste one of the briefs below, change the topic, and the director turns it into a narrated film. Or write your own sentence.

Takes about 30–50 minutes. You can close the page.

What makes an explainer prompt work

The viral one-line showreel prompt gives everyone the same reel. An explainer needs a brief.

One idea per film

A 30-second film explains one thing. Split a big topic into a series.

Say who it is for

A brief for new customers reads differently from one for engineers. Pick the audience in the box too.

Name the look

Write the style you want, such as a whiteboard drawing or a blueprint, so the director does not have to guess.

Give the real numbers

Figures, names and steps you put in the brief end up on screen; anything you leave out gets made up less well.

List what must appear

Use the must-include points for the facts, the product name or the call to action.

Pick the length first

15 seconds holds one point, 60 seconds a short story. The script is cut to it.

Six briefs to start from

Each one matches a sample below. Replace the topic and the numbers with yours.

Whiteboard

Explain how GPS finds your position, as a hand-drawn whiteboard animation: satellites, signal delay, and why four satellites are needed. For curious adults, 45 seconds.

Data story

Tell the story of how solar power became the cheapest electricity, as an animated line chart from 2010 to 2025 with the turning point called out. 30 seconds.

Isometric infographic

Show how a container ship is unloaded at a port, as an isometric infographic: docking, cranes, trucks, customs. 60 seconds.

Glass product

Introduce a water filter bottle in a clean glass-and-light product style: what is inside, how the three stages work, one line on price. 30 seconds.

Dark keynote

Announce a browser tab manager like a keynote on a dark stage: the problem in one number, the feature, the shortcut. 30 seconds, energetic voice.

Blueprint

Explain how an accordion makes sound, as a technical blueprint: bellows, reeds, valves, labelled parts. 45 seconds.

Questions

Why do my Opus 5.5 videos all look the same?
Short prompts let the model fall back on the same palette, grid and closing logo. Name a style, a topic and real numbers, and the films start to differ.
Do I need to set a reasoning level?
No. That matters when you prompt Opus 5.5 yourself; here the director is already set up for long, careful work.
Can I paste a showreel prompt?
You can, but this site makes narrated explainers, so a reel with no topic gives a weak film. Give it something to explain.
Can I reuse a brief for a series?
Yes. Keep the style and the audience the same and change only the topic, and the films will feel like one series.
Is this an Anthropic product?
No. This is an independent site. Our director runs on Claude Opus 5.5 through the API, and Claude and Opus are trademarks of Anthropic.
How long does a film take?
About 30 to 50 minutes. You can close the page; the film waits for you under My films, and your credits come back if it fails.
