World as 100 people (icons + stat race + punchline)
Template (assume duration 10 unless scaled): 0–2s shrink the world to 100 people; 2–9s rapid visual changes (wealth split, gender, access to water/internet, etc.—user picks themes); 9–10s one shocking or memorable stat line (user-themed). English on-screen text with exact windows. Default duration is 10 when unspecified.
Dependencies: WERYAI_API_KEY + Node.js 18+. scripts/video_gen.js + WERYAI_VIDEO_API.md. No other Cursor skills required.
Prerequisites
WERYAI_API_KEY must be set; Node 18+. Prefer public https image URLs; if the assembled scripts/video_gen.js supports local file paths, review/verify the script and explicitly consent before local read-and-upload to WeryAI.- Non-empty
model in JSON.
Security, secrets, and API hosts
WERYAI_API_KEY: Secret; never commit.- API hosts fixed in
video_gen.js as in sibling skills—only the key is read from env.
- Local image handling disclosure: Prefer public
https image URLs. If the assembled scripts/video_gen.js supports local file paths, it may read a local image and upload it to WeryAI to obtain a public URL; require review / verification and explicit consent before using that path.
- Higher assurance: Prefer a short-lived or isolated environment; review
scripts/video_gen.js before production use. Verify whether the runtime can read local image files and upload them to WeryAI, and obtain explicit consent before using that path.
Prompt expansion (mandatory)
- Duration: Default 10; 5 or 15 when allowed and requested.
- Timeline scaling: Rescale hook / middle / punchline segments proportionally; keep hook → three middle beats → final punchline order.
Locked rhythm (example for duration 10):
- 0.0–2.0s — Hook: e.g. SHRINK EARTH TO 100 PEOPLE.
- 2.0–4.0s, 4.0–6.0s, 6.0–9.0s — Three rotating stat / theme lines (user brief): e.g. WEALTH SHIFTS / GENDER / WHO GETS WHAT—keep labels short; pair each with icon morph, pie wipe, or counter tick.
- 9.0–10.0s — Punchline stat (one short English line the user intends—e.g. ONLY X HAVE Y).
Visuals: Isometric or flat UI icons, glow, snappy transitions (~1s); no tiny unreadable numbers unless the caption carries the readable stat.
Typography: Bold sans, outline, lower third; English only unless user requests otherwise.
Audio: Light digital ticks / whoosh if audio on.
Negatives (Kling): garbled numbers, illegible text, watermark.
Confirmation: Full expanded prompt in table.
Niche checklist
- Prefer one clear metaphor per middle window.
- Punchline must be one screenful—no paragraph.
Workflow
- Text / image / multi-image (SEEDANCE_2_0 only, ≤3 URLs).
- Collect which stats or angles to imply (user may give Chinese—translate lines to English on screen).
- Expand with timed captions + motion graphics language.
- Validate JSON vs frozen tables.
- Confirm →
wait.

Definition of done
Video or error; prompt includes 0–2 / 2–4 / 4–6 / 6–9 / 9–10 (or user-approved adjustment) subtitle schedule.
Boundaries (out of scope)
- Not verified census data—illustrative motion; user owns factual claims.
- No
negative_prompt on Seedance; no unsupported fields.

Text-to-video (primary)
User lists themes → you assign lines + seconds → confirm → wait.
Image-to-video (optional)
Charts / icons stills → animate under same windows.
Tips
- If user gives too many themes, merge into three middle beats.
- Punchline hits harder with a contrast number (still short).
