Full prompt 863 characters
Make a dynamic 15-second vertical motion graphics video where "【Name】" celebrates 【Milestone】 and says "【Greeting】". Make the number the hero. Go all out and make the music in code.
Rules: 1080x1920 vertical, 60 fps, exactly 15 seconds, MP4 with sound. Text big enough to read on a phone. No corner labels, timecodes or captions, only the motion. Keep moving to the end with no frozen frames. For Korean text use a Korean font such as @fontsource/black-han-sans. Do it all now without asking.

[Final output format]
Output size 1080x1920 pixels, 9:16 portrait story. Keep all text inside the central 80% of the height.
This selected output format takes priority over any fixed canvas size or aspect ratio elsewhere in this template. Adapt the composition, text zones and margins to the selected canvas without stretching or cropping essential content. Device safe areas apply only when a device is selected.

How to use it · FAQ

The number is the hero

A 15-second vertical motion video counts up a big milestone and says thank you. The example cover shows black concentric circles on purple, huge lime-green milestone text, a cream name and thank-you, and orange starbursts. Its text is in Korean. The prompt asks for music made in code too.

How to fill it in

Use your brand or account name. Give both the number and what it measures, such as “100,000 visits”. Keep the greeting short so it reads well on a phone. You can start with the defaults.

Ask for fixes like this

Tell the AI: “Make the number bigger”, “Count a little more slowly”, “Give the greeting more reading time”, or “Turn the music down a little”.

How we made it

We ran this prompt once with GPT-6 Astra and posted the result as the example without edits. Results vary a little on every run.

What your PC needs

Your PC may slow down briefly while the video is made. This prompt is for an AI that writes and runs code, such as Claude Code or Codex, so an image AI will not produce the video. Check each outside service for its own pricing and terms.
