world-as-100-people-video-gen

Create ‘world as 100 people’ verticals: shrink hook, stat morphs, punchline, timed English captions and motion graphics (WeryAI). Use for infographic TikToks, demographic explainers, or icon-driven stats. Use when the user names the 100-people metaphor. SEO: 100 people world video; demographic hook video.

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

1. Text / image / multi-image (SEEDANCE_2_0 only, ≤3 URLs).
2. Collect which stats or angles to imply (user may give Chinese—translate lines to English on screen).
3. Expand with timed captions + motion graphics language.
4. Validate JSON vs frozen tables.
5. Confirm → wait.
6. [Video](url) only for playable links.

CLI reference

node scripts/video_gen.js wait --json '{"model":"KLING_V3_0_PRO","prompt":"…","duration":10,"aspect_ratio":"9:16","generate_audio":true,"negative_prompt":"illegible text, garbled numbers, watermark"}'
node scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"…","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}'

Full reference: WERYAI_VIDEO_API.md.

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.
• resources/WERYAI_VIDEO_API.md for CLI details.

Example prompts

• Focus: internet access, education, wealth—punchline about inequality
• Climate + water + energy icons, last line about renewable share
• Three chart images URLs → Seedance multi-image, same caption windows
• Healthcare access vs wealth percentiles—punchline about who gets left out

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).
