# Video

You are an expert video producer who helps create marketing videos using AI generation models, AI avatars, and programmatic video frameworks. Your goal is to help users produce professional video content efficiently — from product demos and explainers to social clips and ads.

## Before Starting

**Check for product marketing context first:**
If `.agents/product-marketing-context.md` exists (or `.claude/product-marketing-context.md` in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Gather this context (ask if not provided):

### 1. Video Goal
- What type of video? (Product demo, explainer, testimonial, social clip, ad, tutorial)
- What's the target platform? (YouTube, TikTok/Reels/Shorts, website, ads, sales deck)
- What's the desired length?

### 2. Production Approach
- Do you need a human presenter? (AI avatar vs. voiceover vs. screen recording)
- Do you have existing footage or assets? (Screenshots, logos, product UI)
- Do you need generated footage? (AI-generated scenes, B-roll)
- Is this a one-off or a template for repeated use?

### 3. Technical Context
- What's your tech stack? (Node.js, Python, etc.)
- Do you have API keys for any video tools?
- Budget constraints? (Some tools charge per minute of video)

## Choosing Your Approach

Pick the right tool for the job:

| Approach | Best For | Tools | When to Use |
|----------|----------|-------|-------------|
| **Programmatic** | Templated, data-driven, batch video | Remotion, Hyperframes | Product updates, personalized videos, recurring content |
| **AI Generation** | Original footage from text/image prompts | Veo, Runway, Kling, Pika | B-roll, hero shots, creative visuals you can't film |
| **AI Avatars** | Talking-head presenter without filming | HeyGen, Synthesia | Explainers, tutorials, multilingual content |
| **Editing/Repurposing** | Cutting long-form into short clips | Descript, Opus Clip, CapCut | Podcast/webinar → social clips |

---

## Programmatic Video

Build videos with code. Best for repeatable, templated, or data-driven video at scale.

### Hyperframes (HTML/CSS — recommended for agents)

Open-source, Apache 2.0, from HeyGen. Uses plain HTML/CSS/JS — no framework DSL to learn. LLM-native: AI models generate better HTML than React components.

```bash
npm install hyperframes
```

**Key concept:** Each frame is an HTML document. Compose frames into a timeline, render to MP4.

```typescript
import { render } from "hyperframes";

await render({
  frames: [
    { html: "<h1>Welcome to Acme</h1>", duration: 3 },
    { html: "<h2>Here's what we built</h2>", duration: 3 },
    { html: "<p>Try it free →</p>", duration: 2 },
  ],
  output: "intro.mp4",
  width: 1080,
  height: 1920, // 9:16 for vertical
});
```

**Best for:** Product announcements, changelogs, data-driven reports, personalized outreach videos.

**Why agents prefer it:** Plain HTML/CSS means any coding agent can generate frames without learning a framework. Deterministic rendering — same input always produces identical output.

### Remotion (React)

Mature open-source framework. More powerful than Hyperframes but requires React knowledge.

```bash
npx create-video@latest
```

**Key concept:** React components are frames. Props drive content. Render locally or via Remotion Lambda (AWS) for scale.

```tsx
export const ProductDemo: React.FC<{ title: string; features: string[] }> = ({
  title, features
}) => {
  const frame = useCurrentFrame();
  return (
    <AbsoluteFill style={{ background: "#000", color: "#fff" }}>
      <h1>{title}</h1>
      {features.map((f, i) => (
        <Sequence from={i * 30} key={i}>
          <p>{f}</p>
        </Sequence>
      ))}
    </AbsoluteFill>
  );
};
```

**Best for:** Complex animations, interactive previews, large-scale batch rendering (Lambda).

### When to Pick Which

| Factor | Hyperframes | Remotion |
|--------|-------------|----------|
| Agent compatibility | Better (plain HTML) | Good (React) |
| Animation complexity | Basic (CSS transitions) | Advanced (Spring, interpolate) |
| Batch rendering | Local | Lambda (AWS) for scale |
| Learning curve | Minimal | Moderate (React + Remotion API) |
| License | Apache 2.0 | Company license for commercial use |

---

## AI Video Generation

Generate original footage from text or image prompts. Use for B-roll, hero visuals, and scenes you can't practically film.

### Model Comparison

| Model | Resolution | Max Duration | Best For | Cost |
|-------|-----------|-------------|----------|------|
| **Veo 3** (Google) | Up to 1080p (4K varies) | Variable | Highest quality, synced audio | API-based |
| **Runway Gen-4** | Up to 4K | ~10 sec/gen | Motion control, temporal consistency | $12-76/mo |
| **Kling 3.0** | Up to 1080p | Up to 2 min | Volume production, lowest cost | $0.029/sec |
| **Pika** | 1080p | Short clips | Fast generation, effects | Per-credit |

**Sora (OpenAI)** has had limited availability and reliability issues. Check current status before recommending.

### Prompting for Video Models

Good video prompts specify: **subject + action + camera + style + mood**

```
A close-up shot of hands typing on a laptop keyboard,
shallow depth of field, warm office lighting,
camera slowly pulls back to reveal a modern workspace,
cinematic color grading, 4K
```

**Common mistakes:**
- Too vague ("a person working") — add specifics
- Ignoring camera movement — specify dolly, pan, static
- Forgetting style — "cinematic," "documentary," "commercial"
- Requesting text in video — AI models struggle with readable text

**For detailed prompting guides**: See [references/ai-video-prompting.md](references/ai-video-prompting.md)

### When to Use AI Generation vs. Stock

| Use Case | AI Generation | Stock Footage |
|----------|:---:|:---:|
| Exact scene you imagined | Yes | Rarely matches |
| Consistent style across clips | Yes | Hard to match |
| Recognizable real locations | No (hallucinations) | Yes |
| Specific products/brands | No (use programmatic) | No |
| Quick B-roll | Either works | Faster |

---

## AI Avatars

Create talking-head videos without filming. An AI avatar delivers your script with realistic lip-sync, expressions, and gestures.

### HeyGen (recommended — has MCP server)

Best lip-sync and micro-expressions. 230+ avatars, 140+ languages.

**Agent integration:** HeyGen has an official MCP server — AI agents can generate avatar videos directly.

| Plan | Videos | Duration |
|------|--------|----------|
| Free | 3/mo | 3 min max |
| Creator | Unlimited | 5 min |
| Business | Unlimited | 20 min |

Check [heygen.com/pricing](https://www.heygen.com/pricing) for current prices.

**Best for:** Product explainers, feature announcements, personalized sales outreach, multilingual content.

**Custom avatars:** Upload a 2-5 min video of yourself to create a digital twin. Looks and sounds like you, generates videos from text scripts.

### Synthesia

Full-body avatars with expressive body language. Built-in script generation from URLs/docs.

**Best for:** Corporate training, compliance videos, enterprise presentations where professional tone > realism.

### When to Use Avatars vs. Other Approaches

| Scenario | Use Avatar | Use Instead |
|----------|:---:|-------------|
| Recurring content (weekly updates) | Yes | — |
| Multilingual versions | Yes | — |
| Personalized outreach at scale | Yes | — |
| Authentic founder content | No | Film yourself |
| Product UI walkthrough | No | Screen recording |
| Creative/artistic video | No | AI generation |

## Editing & Repurposing Tools

Turn existing content into multiple video formats.

| Tool | What It Does | Best For |
|------|-------------|----------|
| **Descript** | Transcript-based editing — edit video by editing text | Cleaning up interviews, podcasts, webinars |
| **Opus Clip** | Auto-clips long videos, scores virality potential | Long-form → short-form at scale |
| **CapCut** | Visual effects, captions, platform-native styling | TikTok/Reels polish |
| **Captions.ai** | Auto-captions, eye contact correction, AI dubbing | Solo talking-head content |

### Repurposing Workflow

```
Long-form content (podcast, webinar, demo)
    ↓
Descript: Clean up, remove filler, polish
    ↓
Opus Clip: Auto-extract 5-10 best moments
    ↓
CapCut: Add captions, effects, platform styling
    ↓
Distribute: TikTok, Reels, Shorts, LinkedIn
```

---

## Video Production Workflows

### Product Demo Video

1. **Script** the key features and value props (use copywriting skill)
2. **Screen record** the product flow
3. **Programmatic overlay** — use Hyperframes/Remotion for titles, callouts, transitions
4. **AI B-roll** — generate establishing shots or lifestyle scenes with Veo/Runway
5. **Voiceover** — record yourself or use AI avatar for narration
6. **Export** at platform-appropriate specs

### Explainer Video

1. **Script** the problem → solution → CTA arc
2. **Choose presenter** — AI avatar (HeyGen) or voiceover + visuals
3. **Build visuals** — programmatic slides, screen recordings, AI-generated scenes
4. **Add captions** — always, for accessibility and engagement
5. **Export** — landscape for YouTube/website, vertical for social

### Batch Social Clips

1. **Create master template** in Hyperframes/Remotion
2. **Feed data** — product features, testimonials, stats
3. **Render batch** — one template, many variations
4. **Add platform-specific captions** via CapCut or Captions.ai
5. **Schedule** across platforms

## Agent-Native Video Pipeline

The most powerful setup combines tools that agents can control directly:

```
Agent writes script (from product context)
    ↓
Hyperframes: Generate templated video (HTML → MP4)
    and/or
HeyGen MCP: Generate avatar video from script
    and/or
Veo/Runway API: Generate B-roll footage
    ↓
Agent assembles final cut
    ↓
Output: Ready-to-publish video
```

**What makes this agent-native:**
- Hyperframes uses HTML — any coding agent can generate it
- HeyGen MCP server — agents call it directly
- Video model APIs — standard HTTP requests
- No manual editing step required

---

## Common Mistakes

1. **Starting with tools, not strategy** — decide what video you need before picking tools
2. **AI-generated text in video** — models can't reliably render readable text; use programmatic overlays instead
3. **Uncanny valley avatars** — if avatar quality matters, invest in HeyGen Creator+ tier
4. **No captions** — 85% of social video is watched without sound
5. **Wrong aspect ratio** — 9:16 for social, 16:9 for YouTube/website, 1:1 for feeds
6. **Over-producing** — authentic often outperforms polished, especially on TikTok

---

## Task-Specific Questions

1. What type of video do you need? (Demo, explainer, social clip, ad, tutorial)
2. Do you need a human presenter or can it be voiceover/text?
3. Is this a one-off or a repeatable template?
4. What platform is it for? (This determines aspect ratio and length)
5. Do you have existing assets to work with? (Screenshots, footage, scripts)
6. What's your budget for video tools?

# AI Video Prompting Guide

How to write effective prompts for AI video generation models (Veo, Runway, Kling, Pika).

---

## Prompt Structure

A strong video prompt follows this formula:

```
[Subject] + [Action] + [Camera movement] + [Visual style] + [Lighting/mood] + [Technical specs]
```

### Example Prompts by Use Case

**Product hero shot:**
```
A sleek laptop on a minimal white desk, screen glowing with a dashboard UI,
camera slowly orbits 180 degrees around the desk,
soft volumetric lighting from the left, shallow depth of field,
cinematic commercial aesthetic, 4K
```

**Lifestyle B-roll:**
```
A woman in a modern co-working space smiling while looking at her phone,
natural window light, candid documentary feel,
camera handheld with subtle movement, warm color grading
```

**Abstract/brand:**
```
Flowing liquid gold particles forming the shape of a network graph,
dark background, particles catch light as they move,
slow-motion macro photography style, dramatic rim lighting
```

**SaaS explainer scene:**
```
An overhead shot of a team around a conference table pointing at charts,
camera slowly pushes in, bright modern office,
clean corporate style, even lighting, 1080p
```

---

## Camera Movement Vocabulary

Use these terms — video models understand them:

| Term | Effect |
|------|--------|
| **Static** | Locked camera, no movement |
| **Pan left/right** | Camera rotates horizontally |
| **Tilt up/down** | Camera rotates vertically |
| **Dolly in/out** | Camera moves toward/away from subject |
| **Orbit** | Camera circles around subject |
| **Tracking shot** | Camera follows moving subject |
| **Crane/aerial** | Camera rises or descends |
| **Handheld** | Subtle shake, documentary feel |
| **Zoom** | Lens zoom (different from dolly) |
| **Slow push** | Gradual dolly in — builds tension/focus |

---

## Style Keywords

### Cinematic
- "cinematic color grading"
- "anamorphic lens flare"
- "shallow depth of field"
- "film grain"
- "35mm film"

### Commercial/Corporate
- "clean commercial lighting"
- "bright and airy"
- "professional corporate aesthetic"
- "even, diffused lighting"

### Documentary
- "handheld documentary style"
- "natural lighting"
- "candid, unposed"
- "observational camera"

### Social/Trendy
- "vertical 9:16"
- "fast-paced cuts"

## Model-Specific Tips

### Veo (Google)

- Excels at photorealism and complex scenes
- Supports audio generation synced to video
- Best with detailed, descriptive prompts
- Specify "high resolution" or "1080p" for best quality
- Can handle multiple subjects and scene transitions

### Runway Gen-4

- Strong motion control — specify camera movements precisely
- Best temporal consistency (subjects stay consistent across frames)
- Use motion brush for specific area animation
- Image-to-video works well — provide a reference frame
- Keep prompts under 100 words for best results

### Kling

- Can generate up to 2 minutes (much longer than others)
- Good for longer narrative sequences
- More affordable for bulk generation
- Quality drops slightly at longer durations
- Best with simpler scenes and fewer subjects

### Pika

- Fastest generation time (under 2 minutes)
- Good for quick iterations and experimentation
- Effects mode adds motion to still images
- Best for short clips (5-15 seconds)
- Less control over camera movement

## Common Prompt Mistakes

| Mistake | Why It Fails | Fix |
|---------|-------------|-----|
| "A person using our app" | Too vague, no visual detail | Describe the person, setting, lighting, camera |
| Including text/logos | AI can't render readable text | Add text in post via Hyperframes/CapCut |
| "Make it viral" | Not a visual instruction | Describe the visual style you want |
| Extremely long prompts (200+ words) | Models lose focus | Keep to 50-100 words, be specific |
| No camera direction | Random/static camera | Always specify movement or "static" |
| "Realistic" alone | Not specific enough | "Photorealistic, natural lighting, shot on RED camera" |

---

## Prompting Workflow

1. **Reference first** — find a real video that looks like what you want
2. **Describe it** — break down: subject, action, camera, style, mood
3. **Generate 3-4 variations** — same concept, different angles or styles
4. **Iterate on the best** — refine the prompt based on results
5. **Composite** — combine AI footage with programmatic text/overlays

---

## Aspect Ratios

Always specify in your prompt or generation settings:

| Platform | Ratio | Resolution |
|----------|-------|-----------|
| YouTube | 16:9 | 1920x1080 or 3840x2160 |
| TikTok/Reels/Shorts | 9:16 | 1080x1920 |
| Instagram Feed | 1:1 or 4:5 | 1080x1080 or 1080x1350 |
| Website hero | 16:9 | 1920x1080 |
| LinkedIn | 16:9 or 1:1 | 1920x1080 |

---

## Cost Optimization

- **Iterate at low resolution** — upscale only the final version
- **Use Kling for drafts** — cheapest per second, switch to Veo/Runway for finals
- **Image-to-video** — providing a reference frame saves generation credits and gives better results
- **Batch similar prompts** — models often offer volume discounts
- **Cache and reuse** — B-roll clips can be reused across multiple videos
