title: Website to Video
description: "Capture any website and turn it into a production video with a single prompt."
---

Give your AI agent a URL and a creative direction. It captures the site, extracts the brand identity, writes a script and storyboard, generates voiceover, builds animated compositions, and delivers a renderable video.

```
"Create a 20-second product launch video from https://linear.app.
 Make it feel like an Apple keynote announcement."
```

## Getting Started

<Steps>
  <Step title="Install skills">
    Skills teach your AI agent how to capture websites and create HyperFrames compositions. Install once — they persist across sessions.

    ```bash
    npx skills add heygen-com/hyperframes
    ```

    Works with [Claude Code](https://claude.ai/claude-code), [Cursor](https://cursor.sh), [Gemini CLI](https://github.com/google-gemini/gemini-cli), and [Codex CLI](https://github.com/openai/codex).
  </Step>
  <Step title="Prompt your agent">
    Open your agent in any directory and describe the video you want:

    ```
    Create a 25-second product launch video from https://example.com. Bold, cinematic, dark theme energy.
    ```

    The agent loads the skill when they see a URL and a video request, and runs the full pipeline — capture, design, strategy & messaging, storyboard + script, voiceover, build, validate.

    <Note>
      Agents also trigger this skill automatically when they see a URL and a video request.
    </Note>
  </Step>
  <Step title="Preview">
    ```bash
    npx hyperframes preview
    ```

    Opens the video in your browser. Edits reload automatically.
  </Step>
  <Step title="Render to MP4">
    ```bash
    npx hyperframes render --output my-video.mp4
    ```

    ```
    ✓ Captured 750 frames in 12.4s
    ✓ Encoded to my-video.mp4 (25.0s, 1920×1080, 6.8MB)
    ```
  </Step>
</Steps>

<Note>
  You don't need to run `npx hyperframes capture` manually — the skill instructs the agent to capture as the first step. The capture command is documented [below](#capture-command) for advanced use.
</Note>

## How the Pipeline Works

The skill follows the [Hyperframes pipeline](/guides/pipeline): seven steps, each producing a named artifact that feeds the next.

| Step | Output | What happens |
|------|--------|-------------|
| **Capture** | `capture/` | Extract screenshots, design tokens, fonts, assets, animations |
| **Design** | `DESIGN.md` | Brand reference — colors, typography, component stylings, spacing, iteration guide |
| **Strategy & Messaging** | — | Align on video type, style, the ONE message, and narrative arc |
| **Storyboard + Script** | `STORYBOARD.md` + `SCRIPT.md` | Concept-first storyboard and narration script, written together |
| **VO + Timing** | `narration.wav` + `transcript.json` | TTS audio with word-level timestamps |
| **Build** | `compositions/*.html` | Animated HTML compositions, one per beat |
| **Validate** | Snapshot PNGs + lint/validate pass | Visual verification and runtime checks before delivery |

See [the pipeline guide](/guides/pipeline) for a detailed walkthrough of each step, the contents of every generated file, and how to iterate without re-running the whole pipeline. The structure is useful for any Hyperframes project, not just website captures.

## Video Types

The prompt determines the format. Include a duration and creative direction:

| Type | Duration | Example |
|------|----------|---------|
| Social ad | 10–15s | _"15-second Instagram reel. Energetic, fast cuts."_ |
| Product demo | 30–60s | _"45-second demo showing the top 3 features."_ |
| Feature announcement | 15–30s | _"Feature announcement highlighting the new AI agents."_ |
| Brand reel | 20–45s | _"30-second brand video. Celebrate the design."_ |
| Launch teaser | 10–20s | _"12-second teaser. Super minimal. Just the hook."_ |

<Tip>
  Creative direction matters more than format. _"Playful, hand-crafted feel"_ or _"dark, developer-focused, show code"_ shapes the storyboard and drives every visual decision the agent makes.
</Tip>

## Enriching Captures with Gemini Vision

By default, captures describe assets using DOM context — alt text, nearby headings, CSS classes. Add a vision API key for richer AI-powered descriptions.

Create a `.env` file in your project root with **either** a [Gemini API key](https://aistudio.google.com/apikey):

```bash
echo "GEMINI_API_KEY=your-key-here" > .env
```

…**or**, if you don't have Google access, an [OpenRouter key](https://openrouter.ai/keys) — a single API that fronts many vision models:

```bash
echo "OPENROUTER_API_KEY=your-key-here" > .env
```

OpenRouter is used when its key is present (it takes priority if both are set). The default model is `google/gemini-3.1-flash-lite`; override it with `HYPERFRAMES_OPENROUTER_MODEL` (any vision-capable OpenRouter model), just as `HYPERFRAMES_GEMINI_MODEL` overrides the Gemini default.

<Tabs>
  <Tab title="Without Gemini">
    ```
    - hero-bg.png — 582KB, section: "Hero", above fold
    ```
    The agent knows the file exists and where it was on the page, but not what it looks like.
  </Tab>
  <Tab title="With Gemini">
    ```
    - hero-bg.png — 582KB, A gradient wave in purple and blue sweeps
      across a dark background, creating an aurora-like effect.
    ```
    The agent knows what the image actually shows, enabling better creative decisions in the storyboard.

| Tier | Rate limit | Cost per image |
|------|-----------|----------------|
| Free | 5 RPM | Free |
| Paid | 2,000 RPM | ~$0.001 |

A typical capture with 40 images costs about **$0.04** on the paid tier.

## Capture Command

The skill runs capture automatically, but you can run it directly for pre-caching, debugging, or using the data outside of video production.

```bash
npx hyperframes capture https://stripe.com
```

```
◇  Captured Stripe | Financial Infrastructure → capture

  Screenshots: 12
  Assets: 45
  Sections: 15
  Fonts: sohne-var
```

| Flag | Default | Description |
|------|---------|-------------|
| `-o, --output` | `./capture` | Output directory (auto-suffixes to `./capture-2/`, `./capture-3/`, … if `./capture/` is taken) |
| `--timeout` | `120000` | Page load timeout in ms |
| `--skip-assets` | `false` | Skip downloading images and fonts |
| `--max-screenshots` | `24` | Maximum screenshot count |
| `--json` | `false` | Output structured JSON for programmatic use |

### What Gets Captured

| Data | Description |
|------|-------------|
| **Screenshots** | Viewport captures at every scroll depth — dynamic count based on page height |
| **Colors** | Pixel-sampled dominant colors + computed styles, including oklch/lab conversion |
| **Fonts** | CSS font families + downloaded woff2 files |
| **Assets** | Images, SVGs with semantic names, Lottie animations, video previews |
| **Text** | All visible text in DOM order |
| **Animations** | Web Animations API, scroll-triggered animations, WebGL shaders |
| **Sections** | Page structure with headings, types, background colors |
| **CTAs** | Buttons and links detected by class names and text patterns |

## Snapshot Command

Capture key frames from a built video as PNGs — verify compositions without a full render:

```bash
npx hyperframes snapshot my-project --at 2.9,10.4,18.7
```

| Flag | Default | Description |
|------|---------|-------------|
| `--frames` | `5` | Number of evenly-spaced frames |
| `--at` | — | Comma-separated timestamps in seconds |
| `--timeout` | `5000` | Ms to wait for runtime to initialize |

## Iterating

You don't need to re-run the full pipeline to make changes:

- **Edit the storyboard** — `STORYBOARD.md` is the creative north star. Change a beat's mood or assets, then ask the agent to rebuild just that beat.
- **Edit a composition** — open `compositions/beat-3-proof.html` directly and tweak animations, colors, or layout.
- **Rebuild one beat** — _"Rebuild beat 2 with more energy. Use the product screenshot as full-bleed background."_

See the [pipeline guide](/guides/pipeline#iterating) for more re-entry patterns.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Capture times out">
    Increase the timeout for sites with Cloudflare or heavy client-side rendering:

    ```bash
    npx hyperframes capture https://example.com --timeout 180000
    ```
  </Accordion>
  <Accordion title="Few assets captured">
    Sites using frameworks like Framer lazy-load images via IntersectionObserver. The capture scrolls through the page to trigger loading, but very long pages may miss images near the bottom. Adding a Gemini key improves descriptions of captured assets, but doesn't increase the count.
  </Accordion>
  <Accordion title="Colors look wrong">
    The capture uses pixel sampling combined with DOM computed styles. Dark sites should show dark colors in the palette. Check the scroll screenshots in `<output>/screenshots/` (default `./capture/screenshots/`) to see what the capture actually saw.
  </Accordion>
  <Accordion title="Agent doesn't find the skill">
    Verify skills are installed:

    ```bash
    npx skills add heygen-com/hyperframes
    ```

    Lead your prompt with _"Use the /website-to-video skill"_ for the most reliable results. Agents also discover it automatically when they see a URL and a video request.
