Use when asked to \"make a video about X\", build a title card or animated overlay, add captions or narration, or turn a project/README into a motion piece. HTML is the source of truth — a composition is one HTML file with data-* timing, a seekable GSAP timeline, and CSS.\ntriggers:\n - \"/videomaker\"\n - \"make me a video\"\n - \"make a video about\"\n - \"turn this into a video\"\n - \"promo video\"\n - \"render to mp4\"\n---\n\n# Videomaker\n\nMy workflow for turning an idea into a rendered MP4 with **HyperFrames** (`npx hyperframes`). HTML is the source of truth: one composition file, a single paused GSAP timeline, CSS for looks. The framework seeks the timeline frame-by-frame and captures with headless Chrome, then muxes with FFmpeg.\n\n> Built once with HeyGen's HyperFrames skill (`npx skills add heygen-com/hyperframes`). This card is the distilled, personal version — extend it as I learn more.\n\n## Setup (one-time on this machine)\n\nNeeds **Node 22+** and **FFmpeg + ffprobe**; Chrome is used for capture. On the Deno box neither Node nor ffmpeg is global — they live in `~/.local`, so prefix every command:\n\n```bash\nexport PATH=\"$HOME/.local/node/bin:$HOME/.local/bin:$PATH\"\nnpx hyperframes doctor # verify Node / FFmpeg / Chrome\n```\n\n## Loop\n\n1. **Scaffold:** `npx hyperframes init --example blank --non-interactive --skip-skills --resolution landscape`\n2. **Decide before coding:** concept → palette (bg / fg / one accent, declared up front) → two type voices that *cross* a boundary (serif+mono, not two sans). Name the tension.\n3. **Author `index.html`:** one `data-composition-id` root; scenes are full-frame wrappers crossfaded by **opacity** on the single timeline; elements animate in with `tl.fromTo`.\n4. **Verify cheap, then render:**\n ```bash\n npx hyperframes lint\n npx hyperframes snapshot --at 3,9,15,21 --describe false # eyeball frames first\n npx hyperframes render -o renders/out.mp4 -w 2 -q standard # -w 2 keeps RAM sane\n ```\n\n## Hard-won rules (the linter won't catch these)\n\n- **Fonts must be literal, and bundled.** Write real `font-family` names — *not* CSS `var(--serif)`, or the compiler can't detect them and text falls back to Times. Only `PRODUCER_BUNDLED_FONTS` embed offline. Usable serif ≈ **Garamond** (EB Garamond / Playfair are bundled but are AI-tell banned). Mono: **Space Mono**, JetBrains Mono, IBM Plex Mono.\n- **Timeline must be seekable + deterministic:** build it synchronously (no `async`/`setTimeout`); no `Math.random()` / `Date.now()`; attach every ambient/looping tween to `tl` (never a bare `gsap.to`); prefer `tl.fromTo` inside scenes; **never stack two transform tweens on one element** — put the entrance on a wrapper, the ambient float/rotate on a child.\n- **No exit animations except the final scene** — the crossfade *is* the exit.\n- **Video scale ≠ web scale:** 60px+ headlines, 20px+ body, big padding, decorative opacity 12–25%. Aim ~8–10 elements & two focal points per scene; anchor to edges, not centered-floating.\n- **Avoid the AI tells:** cyan-on-dark, purple→blue gradients, gradient text, neon, pure `#000`/`#fff` (tint toward the accent).\n\n## The card pattern (my favorite — lean on it)\n\nA trading-card layout reads beautifully and is the most interesting thing to animate:\n\n- **Structure:** head (`name` + mana `◆◆◆`) · art window · type line · description · `Say \"\"` (mono) · footer (`Lv N` / foil). Theme per card via a `data-c` color attribute driving CSS custom props.\n- **Entrance:** 3D tilt — `rotationY: -110 → -8` on the card, opacity/scale/y on its wrapper.\n- **Foil (Lv 7+):** an absolutely-positioned overlay, `mix-blend-mode: screen`, gold→white gradient, swept across with `x`.\n- **Flip:** `.flip-inner { transform-style: preserve-3d }`, `rotationY 0 → 180`; back face is `rotateY(180deg)` and holds the SKILL.md text + memory stickers.\n- **Binder shot:** a 3×2 grid of cards in distinct colors, staggered in with `back.out`, gently breathing.\n\n## Ideas to add later\n\nPortrait 9:16 cut for social · built-in TTS narration (`hyperframes tts`) · captions synced to audio · a real drag-reorder beat · pull in the Anthropic deck · 4K via `--resolution 4k`.\n",[],[172,371,34],"videomaker","16f4a39b-b48d-48ab-89d6-b7491b2646b3","reference_toolchain_local.md","46d95ea0-5fb6-11f1-ae28-1607ee4eb77e","3cf53122-160b-4e3d-8629-583dc8a1f296",155,["D",1780537190246],"---\nname: toolchain-in-local\ntype: reference\ndescription: Node 22 + static FFmpeg live in ~/.local on this Deno box — prefix PATH\n---\nThis machine is a Deno setup with **no global Node, npm, or FFmpeg**.

Treat the output as a **static poster in a fixed, no-scroll frame** — not a live web page, and not interactive.\n\n## What triggers a render\n\n- A render only happens when you call **`fetch_val_endpoint`**. The `run: { kind: \"fetch_val_endpoint\" }` option on `update_file` / `replace_in_file` counts, because it calls the same thing.\n- `create_file`, `update_file`, `list_files`, etc. show a *file / diff* widget, **not** the rendered HTML. Don't expect them to preview a page.\n- `fetch_val_endpoint` also returns the response (status + headers + body) to you as text, so it doubles as your inspect/debug tool. The endpoint is public.\n\n## The frame (measured)\n\n- Fixed size **≈ 885 × 386 px** — wide and short, aspect ≈ 2.3:1. It can vary slightly with client width, so design with a little margin.\n- **No scroll.** The iframe is sized to the document's *content height* and then clipped inside the fixed frame. Anything past ~386px tall is **cut off at the bottom** — there is no scrollbar.\n- You don't control the frame height from inside it, so you can't vertically center to it. Top-aligned content with empty space below is fine; overflow is not.\n\n## Hard rules (break these and the render fails)\n\n- **Never use `height:100vh`, `height:100%` on html/body, or `position:fixed` for layout.** Because the iframe is content-sized, viewport-relative heights resolve to ~0 and the whole thing renders **blank**. Use **normal document flow** with `auto` / explicit `px` heights.\n- **It is not interactive.** Clicks do not toggle CSS `:checked`, fire handlers, or submit forms — a click appears to **open / navigate to the val** instead. So:\n - No tabs, accordions, modals, hover-to-reveal, or anything that needs a click or tap.\n - Don't rely on `\n \n\n\n

\n \n\n\n```\n\n**CRITICAL**: This is a single artifact. No external files, no imports (except p5.js CDN). Everything inline.\n\n**4. Implementation Details - BUILD THE SIDEBAR**\n\nThe sidebar structure:\n\n**1. Seed (FIXED)** - Always include exactly as shown:\n- Seed display\n- Prev/Next/Random/Jump buttons\n\n**2. Parameters (VARIABLE)** - Create controls for the art:\n```html\n

\n Parameter Name\n \n ...\n

\n```\nAdd as many control-group divs as there are parameters.\n\n**3. Colors (OPTIONAL/VARIABLE)** - Include if the art needs adjustable colors:\n- Add color pickers if users should control palette\n- Skip this section if the art uses fixed colors\n- Skip if the art is monochrome\n\n**4. Actions (FIXED)** - Always include exactly as shown:\n- Regenerate button\n- Reset button\n- Download PNG button\n\n**Requirements**:\n- Seed controls must work (prev/next/random/jump/display)\n- All parameters must have UI controls\n- Regenerate, Reset, Download buttons must work\n- Keep Anthropic branding (UI styling, not art colors)\n\n### USING THE ARTIFACT\n\nThe HTML artifact works immediately:\n1. **In claude.ai**: Displayed as an interactive artifact - runs instantly\n2. **As a file**: Save and open in any browser - no server needed\n3. **Sharing**: Send the HTML file - it's completely self-contained\n\n---\n\n## VARIATIONS & EXPLORATION\n\nThe artifact includes seed navigation by default (prev/next/random buttons), allowing users to explore variations without creating multiple files. If the user wants specific variations highlighted:\n\n- Include seed presets (buttons for \"Variation 1: Seed 42\", \"Variation 2: Seed 127\", etc.)\n- Add a \"Gallery Mode\" that shows thumbnails of multiple seeds side-by-side\n- All within the same single artifact\n\nThis is like creating a series of prints from the same plate - the algorithm is consistent, but each seed reveals different facets of its potential. The interactive nature means users discover their own favorites by exploring the seed space.\n\n---\n\n## THE CREATIVE PROCESS\n\n**User request** → **Algorithmic philosophy** → **Implementation**\n\nEach request is unique. The process involves:\n\n1. **Interpret the user's intent** - What aesthetic is being sought?\n2. **Create an algorithmic philosophy** (4-6 paragraphs) describing the computational approach\n3. **Implement it in code** - Build the algorithm that expresses this philosophy\n4. **Design appropriate parameters** - What should be tunable?\n5. **Build matching UI controls** - Sliders/inputs for those parameters\n\n**The constants**:\n- Anthropic branding (colors, fonts, layout)\n- Seed navigation (always present)\n- Self-contained HTML artifact\n\n**Everything else is variable**:\n- The algorithm itself\n- The parameters\n- The UI controls\n- The visual outcome\n\nTo achieve the best results, trust creativity and let the philosophy guide the implementation.\n\n---\n\n## RESOURCES\n\nThis skill includes helpful templates and documentation:\n\n- **templates/viewer.html**: REQUIRED STARTING POINT for all HTML artifacts.\n - This is the foundation - contains the exact structure and Anthropic branding\n - **Keep unchanged**: Layout structure, sidebar organization, Anthropic colors/fonts, seed controls, action buttons\n - **Replace**: The p5.js algorithm, parameter definitions, and UI controls in Parameters section\n - The extensive comments in the file mark exactly what to keep vs replace\n\n- **templates/generator_template.js**: Reference for p5.js best practices and code structure principles.\n - Shows how to organize parameters, use seeded randomness, structure classes\n - NOT a pattern menu - use these principles to build unique algorithms\n - Embed algorithms inline in the HTML artifact (don't create separate .js files)\n\n**Critical reminder**:\n- The **template is the STARTING POINT**, not inspiration\n- The **algorithm is where to create** something unique\n- Don't copy the flow field example - build what the philosophy demands\n- But DO keep the exact UI structure and Anthropic branding from the template",[],[172,1048,34],"anthropic-algorithmic-art","c6628842-5974-11f1-9c4b-ee650bb23af1",91,["D",1779849350455],[198],[172,1048],["D",1779816059463],[197,199,201,203,205,207,209,211,213,215,217,219,221,223,225,227,229,231,240,248,257,258,267,279,281,290,292,298],[172],"cf7ec45e-5974-11f1-b3e1-ee650bb23af1","loader.ts","ae9857de-5927-11f1-8d94-ee650bb23af1",126,["D",1779849365719],"// Loads skills off disk by walking the `skills/` directory.\n//\n// Layout (a standard \"skill repo\" shape, agent-readable as-is):\n//\n// skills/\n// _index.json ← binder-only card metadata\n// /\n// SKILL.md ← YAML frontmatter + markdown body\n// memories/_.md ← per-memory files (frontmatter typed)\n// templates/.md\n// scripts/.ts\n\nimport { listFilesByPath, readFile } from \"https://esm.town/v/std/utils/index.ts\";\nimport { parse as parseYaml } from \"https://esm.sh/yaml@2.5.0\";\n\nexport type SkillColor = \"blue\" | \"white\" | \"black\" | \"red\" | \"green\" | \"gold\" | \"anthropic\";\n\nexport interface Memory {\n kind: \"feedback\" | \"project\" | \"reference\" | \"user\";\n slug: string;\n title: string;\n description?: string;\n body: string;\n}\n\nexport interface Skill {\n slug: string;\n name: string;\n description: string;\n triggers: string[];\n body: string;\n\n deck: string;\n deck?: string;\n type: string;\n color: SkillColor;\n art: string;\n artPrompt: string;\n manaCost: number;\n level: number;\n invocations: number;\n lastUsed: string;\n flavor: string;\n\n memories: Memory[];\n templates: string[];\n scripts: string[];\n}\n\ninterface CardMeta {\n type: string;\n color: SkillColor;\n art: string;\n artPrompt: string;\n manaCost: number;\n level: number;\n invocations: number;\n lastUsed: string;\n flavor: string;\n}\n\ninterface FileEntry {\n path: string;\n name?: string;\n type?: string;\n}\n\nlet cached: Skill[] | null = null;\n\nexport async function loadSkills(): Promise {\n if (cached) return cached;\n const indexText = await readFile(\"/skills/_index.json\", import.meta.url);\n const index = JSON.parse(indexText) as Record;\n\n // One recursive listing under skills/ — everything in one round-trip.\n const allFiles = (await listFilesByPath(\"skills\", import.meta.url)) as FileEntry[];\n\n const order = Object.keys(index).filter((k) => !k.startsWith(\"_\"));\n const skills = await Promise.all(\n order.map((slug) => loadOne(slug, index[slug] as CardMeta, allFiles)),\n );\n cached = skills;\n return skills;\n}\n\nasync function loadOne(slug: string, meta: CardMeta, allFiles: FileEntry[]): Promise {\n const prefix = `skills/${slug}/`;\n const filesForSkill = allFiles.filter((f) => f.path?.startsWith(prefix));\n\n const body = await readFile(`/skills/${slug}/SKILL.md`, import.meta.url);\n const { frontmatter } = splitFrontmatter(body);\n\n const memoryFiles = filesForSkill.filter(\n (f) => f.path.startsWith(`${prefix}memories/`) && f.path.endsWith(\".md\"),\n );\n const memories = await Promise.all(memoryFiles.map(loadMemory));\n\n const templates = filesForSkill\n .filter((f) => f.path.startsWith(`${prefix}templates/`) && f.type !== \"directory\")\n .map((f) => basename(f.path))\n .sort();\n const scripts = filesForSkill\n .filter((f) => f.path.startsWith(`${prefix}scripts/`) && f.type !== \"directory\")\n .map((f) => basename(f.path))\n .sort();\n\n return {\n slug,\n name: String(frontmatter.name ?? slug),\n description: String(frontmatter.description ?? \"\"),\n triggers: Array.isArray(frontmatter.triggers) ? frontmatter.triggers.map(String) : [],\n body,\n deck: meta.deck ?? \"Skillbook\",\n type: meta.type,\n color: meta.color,\n art: meta.art,\n artPrompt: meta.artPrompt,\n manaCost: meta.manaCost,\n level: meta.level,\n invocations: meta.invocations,\n lastUsed: meta.lastUsed,\n flavor: meta.flavor,\n memories,\n templates,\n scripts,\n };\n}\n\nasync function loadMemory(f: FileEntry): Promise {\n const text = await readFile(`/${f.path}`, import.meta.url);\n const { frontmatter, body } = splitFrontmatter(text);\n const name = basename(f.path);\n const kind = resolveKind(name, frontmatter);\n const memorySlug = String(frontmatter.name ?? name.replace(/\\.md$/, \"\"));\n return {\n kind,\n slug: memorySlug,\n title: humanize(memorySlug),\n description: frontmatter.description ?
