Rename the `graphic-overlays` workflow skill to `talking-head-recut`: - move skills/graphic-overlays/ -> skills/talking-head-recut/ - update SKILL.md frontmatter name, H1, and self-references - update all /graphic-overlays route references (hyperframes router, general-video, root + cli-template AGENTS.md/CLAUDE.md, docs, quickstart) - update telemetry --skill flag, example composition id, timeline key - update .prettierignore path and scripts/test-skills-fresh.sh Identifier-only rename: the graphic-overlay card mechanism, design references, and trigger wording are unchanged.

# Hyperframes
|
|
|
|
Open-source video rendering framework: write HTML, render video.
|
|
|
|
## Skills
|
|
|
|
This repo ships AI agent skills via [vercel-labs/skills](https://github.com/vercel-labs/skills). Install them before writing compositions — they encode framework-specific patterns that generic docs don't cover.
|
|
|
|
```bash
|
|
npx skills add heygen-com/hyperframes
|
|
```
|
|
|
|
**Video-creation workflows** route through one entry skill — read `/hyperframes` first: it orients you to the whole surface and maps "make me a video" intent to a concrete workflow. Consult it before invoking a specific workflow:
|
|
|
|
- `/product-launch-video` — a **product** URL (or a pre-written script / text brief in no-capture mode) → product launch / promo video, up to ~3 min (sweet spot ~30-90s).
|
|
- `/website-to-video` — a **general** website / URL → a video _of_ the site (tour / showcase / social clip from captured screenshots + assets); for a product **launch / promo**, use `/product-launch-video`.
|
|
- `/faceless-explainer` — arbitrary text, **no URL and no website capture** → faceless explainer, up to ~3 min (sweet spot ~30-90s); every visual is LLM-invented (typography / abstract graphics / diagram / data-viz).
|
|
- `/embedded-captions` — an existing talking-head video (MP4) → the same footage with captions / subtitles added (verbatim rail + embedded climax, or pure-cinematic embed); the footage itself is untouched (no NLE-style editing).
|
|
- `/talking-head-recut` — an existing talking-head / interview / podcast video (MP4) → the same footage packaged with designed **graphic overlays** (kinetic titles, lower-thirds, data callouts, pull-quotes, side panels, pip) synced to the transcript; the clip plays unchanged underneath, footage untouched. Replaces the removed `/footage-recut`. For plain captions/subtitles → `/embedded-captions`.
|
|
- `/pr-to-video` — a GitHub PR (URL / `owner/repo#N` / "this PR") → code-change explainer, up to ~3 min (changelog / feature reveal / fix / refactor). A PR link, not a product website.
|
|
- `/motion-graphics` — a short (typically under 10s) design-led **motion graphic**, motion-is-the-message, no narration: kinetic type, a stat / number count-up, a chart, a logo sting, a lower-third / overlay, or an animated tweet / headline / captured-page highlight; rendered to MP4 or a transparent overlay. Longer / narrated / custom → `/general-video`.
|
|
- `/general-video` — fallback for any other video creation (title card, longer brand / sizzle reel, multi-scene montage, static loop, custom composition); the original hyperframes flow — design → plan → layout → build → validate, any length.
|
|
|
|
**Porting an existing composition?** `/remotion-to-hyperframes` translates a Remotion (React) video composition into HyperFrames HTML — a source migration, separate from the creation workflows above.
|
|
|
|
## Build & Test
|
|
|
|
```bash
|
|
bun install # Install dependencies (NOT pnpm — do not create pnpm-lock.yaml)
|
|
bun run build # Build all packages
|
|
bun run test # Run all tests
|
|
```
|
|
|
|
### Linting & Formatting
|
|
|
|
Uses **oxlint** and **oxfmt** (not eslint, not prettier, not biome).
|
|
|
|
```bash
|
|
bunx oxlint <files> # Lint
|
|
bunx oxfmt <files> # Format
|
|
bunx oxfmt --check <files> # Check formatting (CI / pre-commit)
|
|
```
|
|
|
|
Always lint and format changed files before committing. Lefthook pre-commit hooks enforce this automatically.
|
|
|
|
### Composition Validation
|
|
|
|
After creating or editing any `.html` composition:
|
|
|
|
```bash
|
|
npx hyperframes lint # Static HTML structure check
|
|
npx hyperframes validate # Runtime check (headless Chrome — catches JS errors, missing assets)
|
|
```
|
|
|
|
Both must pass before previewing or considering work complete.
|
|
|
|
## Project Structure
|
|
|
|
```
|
|
packages/
|
|
cli/ → hyperframes CLI (create, preview, lint, render)
|
|
core/ → Types, parsers, generators, linter, runtime, frame adapters
|
|
engine/ → Seekable page-to-video capture engine (Puppeteer + FFmpeg)
|
|
player/ → Embeddable <hyperframes-player> web component
|
|
producer/ → Full rendering pipeline (capture + encode + audio mix)
|
|
shader-transitions/ → WebGL shader transitions for compositions
|
|
studio/ → Browser-based composition editor UI
|
|
registry/
|
|
blocks/ → Installable sub-composition scenes (50+)
|
|
components/ → Installable effects and snippets
|
|
examples/ → Starter project templates
|
|
docs/ → Mintlify documentation site (hyperframes.heygen.com)
|
|

|
## Key Conventions
|
|
|
|
- **Package manager**: bun (not pnpm, not npm for workspace operations)
|
|
- **Commit format**: Conventional commits (`feat:`, `fix:`, `docs:`, `refactor:`, `test:`)
|
|
- **TypeScript**: Avoid `any` and `as T` assertions. Prefer type guards and narrowing.
|
|
- **Compositions**: HTML files with `data-*` attributes. Clips need `class="clip"`. GSAP timelines must be paused and registered on `window.__timelines`.
|
|
- **Frame Adapters**: Animation runtimes plug in via the seek-by-frame adapter pattern. GSAP is the primary adapter.
|
|
- **Deterministic rendering**: No `Date.now()`, no unseeded `Math.random()`, no render-time network fetches.
