## About

# /marketing-demo — Product Demo Recorder

Record product demos for marketing. Two production paths: quick (ply + ffmpeg) for rough demos, polished (Remotion) for branded marketing videos.

## Reads

- `brand/creative-kit.md` — Colors, fonts, logo paths for branded overlays
- `brand/voice-profile.md` — Tone guidance for text overlays
- `brand/stack.md` — Available tools (ply, ffmpeg, remotion)

## On Activation

1. Read `brand/creative-kit.md` for colors, fonts, logo paths. If missing, ask for brand colors and logo.
2. Read `brand/voice-profile.md` for tone guidance on text overlays. If missing, use clear/neutral tone.
3. Read `brand/stack.md` to confirm available tools. If missing, detect tools directly.
4. Check tool availability:
   ```bash
   command -v ply && echo "ply: ready" || echo "ply: missing"
   command -v ffmpeg && echo "ffmpeg: ready" || echo "ffmpeg: missing"
   command -v npx && echo "remotion: available" || echo "remotion: unavailable"
   ```
5. If `ply` or `ffmpeg` missing, warn and suggest install.

## Shot Duration Rules

| Demo Type | Duration per Shot | Notes |
|-----------|------------------|-------|
| Quick overview | 0.5-1s | Fast cuts, build excitement |
| Feature demo | 2-3s | Time to read + comprehend |
| Walkthrough | 4-5s | Instructional pacing |
| Social clip | 1-2s | Attention-grabbing, fast |

## Demo Storytelling Principles

Demos fail when they show the product mechanically instead of telling a story. The viewer needs a reason to keep watching. These principles come from what actually gets engagement on landing pages and social:

1. **Open with the outcome, not the setup.** The first 2 seconds decide if someone watches the rest. Show the "after" state — the dashboard with data, the completed design, the result. Setup (login, loading, navigation) earns zero attention.
2. **One feature = one demo.** Trying to cram 5 features into 30 seconds makes all of them forgettable. A focused demo of one feature is worth more than a rushed tour.
3. **Show the magic moment.** Every product has one interaction where users go "oh wow." Find that moment and build the demo around it — it's why people click "try it."
4. **Add context with text overlays.** Social videos autoplay muted. Without text callouts, viewers see UI changing with no idea what's happening or why it matters. Every shot needs a 3-6 word overlay explaining the value.
5. **Pacing: 2-3 seconds per concept.** This feels fast, but viewer attention is brutal. If a shot doesn't earn its screen time with new information, cut it.

## Step 1: Determine Demo Type

| Type | Duration | Resolution | Format | Use Case |
|------|----------|-----------|--------|----------|
| Hero demo | 15-30s | 1280x800 | MP4 | Landing page above-fold |
| Feature highlight | 5-15s | 1280x800 | GIF/MP4 | Feature section, docs |
| Full walkthrough | 60-180s | 1280x800 | MP4 | YouTube, sales deck |
| Social clip | 5-15s | 1080x1080 | MP4 | Instagram, Twitter/X |
| Email GIF | 3-8s | 600x400 | GIF | Email campaigns |
| How-to | 30-90s | 1280x800 | MP4 | Help docs, onboarding |

Ask the user which type, or infer from context.

## Step 2: Plan Shot List

Before recording, plan each shot:

```markdown
## Shot List

1. [Action: Navigate to landing page]
   - URL: https://example.com
   - Wait: 1s for load
   - Highlight: Hero section

2. [Action: Click "Get Started" button]
   - Wait: transition animation
   - Highlight: Signup form

3. [Action: Fill demo data]
   - Type: demo@example.com
   - Highlight: Success state
```

Each shot = one `ply` screenshot or interaction sequence.

## Step 3: Choose Production Mode

### Mode A: Quick Demo (ply + ffmpeg)

Fast, rough demos from screenshots stitched into video.

**Capture screenshots:**
```bash
# Navigate and screenshot each shot
ply navigate "https://example.com"
ply screenshot --output marketing/demos/shot-01.png
ply click "Get Started"
ply screenshot --output marketing/demos/shot-02.png
```

**Stitch with ffmpeg:**
```bash
# MP4 from screenshots (2 seconds per frame)
ffmpeg -framerate 0.5 -i marketing/demos/shot-%02d.png \
  -c:v libx264 -pix_fmt yuv420p \
  -vf "scale=1280:800:force_original_aspect_ratio=decrease,pad=1280:800:(ow-iw)/2:(oh-ih)/2" \
  marketing/demos/demo.mp4

# Preview GIF (lower quality, smaller file)
ffmpeg -i marketing/demos/demo.mp4 \
  -vf "fps=10,scale=640:-1:flags=lanczos" \
  -c:v gif marketing/demos/demo-preview.gif

# Email GIF (600px wide, optimized)
ffmpeg -i marketing/demos/demo.mp4 \
  -vf "fps=8,scale=600:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \
  marketing/demos/demo-email.gif

# Square crop for social (1080x1080)
ffmpeg -i marketing/demos/demo.mp4 \
  -vf "crop=min(iw\,ih):min(iw\,ih),scale=1080:1080" \
  marketing/demos/demo-square.mp4
```

### Mode B: Polished Demo (Remotion)

For marketing-grade output with transitions, text overlays, branded intros.

**Generate Remotion composition:**
```bash
# Initialize if needed
npx remotion init marketing/demos/remotion-demo

# Render final video
npx remotion render marketing/demos/remotion-demo/src/index.tsx \
  --output marketing/demos/demo-polished.mp4
```

**Composition structure:**
```
src/
├── index.tsx          # Root composition
├── Intro.tsx          # Branded intro (logo, tagline)
├── DemoScene.tsx      # Screenshot with text overlay
├── Transition.tsx     # Fade/slide between scenes
└── Outro.tsx          # CTA + URL
```

**Key Remotion patterns** (see [references/remotion-examples.md](references/remotion-examples.md) for complete component code):
- Use `` for screenshots, `` for layout
- `useCurrentFrame()` + `interpolate()` for animations
- Pull brand colors from `brand/creative-kit.md`
- 30fps for smooth playback, 1280x720 or 1920x1080
- Add text overlays calling out features with ``

**Intro scene (2-3s):** Logo centered, tagline fades in. Brand colors as background gradient. Keep it short — the product is the star.

**Demo scene (per shot):** Screenshot fills 80% of frame. Text overlay at top or bottom with 1-line feature callout. Use `interpolate()` for a subtle zoom-in (1.0 → 1.05 over the scene duration) to add life.

**Transition between scenes:** Fade + slight slide (200ms). Never use fancy wipes — they distract from the product.

**Outro scene (3-4s):** CTA text ("Try it free at [url]"), logo, and optional social proof line. This is the only slide that sells — keep all other slides focused on showing.

### Error Recovery

**ply failures** (page doesn't load, element not found, timeout): Skip to shot N+1 and document the failure in the shot list. After all shots complete, review skipped shots and retry once. If still failing, use manual screenshots as fallback.

**ffmpeg failures** (codec not found, format error): Check `ffmpeg -codecs` for available codecs. If libx264 is missing, try `-c:v h264` or install via `brew install ffmpeg`. For GIF palette issues, simplify the filter chain — drop `split/palettegen/paletteuse` and use basic `-vf "fps=10,scale=640:-1"`.

**Remotion failures** (render crashes, composition errors): Check node version (`node -v`, needs 18+). If `npx remotion render` fails, try `npx remotion render --gl=angle` or `--gl=swangle` for GPU issues. For composition errors, verify all `` src paths are correct and images exist.

## Step 4: Convert & Output

All outputs go to `marketing/demos/`. Name by type:

| Output | Filename | Notes |
|--------|----------|-------|
| MP4 (desktop) | `demo-hero.mp4` | H.264, 1280x800 |
| MP4 (social) | `demo-social-1080.mp4` | Square, 1080x1080 |
| GIF (preview) | `demo-preview.gif` | 640px wide, <5MB |
| GIF (email) | `demo-email.gif` | 600px wide, <2MB |
| MP4 (polished) | `demo-polished.mp4` | Remotion output |

## Step 5: Completion Summary

```markdown
## Demo Assets Created

| Asset | Size | Format | Suggested Use |
|-------|------|--------|--------------|
| demo-hero.mp4 | 1.2MB | MP4 1280x800 | Landing page hero |
| demo-preview.gif | 3.4MB | GIF 640px | README, docs |
| demo-email.gif | 1.1MB | GIF 600px | Email campaigns |
| demo-social-1080.mp4 | 800KB | MP4 1080x1080 | Instagram, X |

All assets saved to `marketing/demos/`.
```

## Viewport Configs

| Platform | Width | Height | Scale |
|----------|-------|--------|-------|
| Desktop | 1280 | 800 | 1x |
| Desktop HD | 1920 | 1080 | 1x |
| Mobile | 390 | 844 | 2x |
| Instagram | 1080 | 1080 | 1x |
| Twitter/X | 1200 | 675 | 1x |
| Email | 600 | 400 | 1x |

## Anti-Patterns

| Mistake | Why It Fails |
|---------|-------------|
| Recording login/signup flows | Nobody cares about your auth screen. Start after login. |
| Showing loading spinners | Edit them out or skip to the loaded state. Spinners kill momentum. |
| No text overlays on silent autoplay | Social videos autoplay muted. Without text, viewers have no idea what they're watching. |
| Demo longer than 60s without chapter breaks | Attention drops after 15s. If it's long, add clear section titles. |
| Recording at inconsistent viewport sizes | Shots that jump between sizes look amateur. Lock viewport before recording. |
| Showing every feature | Pick 3-5 features max. Demos that show everything sell nothing. |
| Mouse cursor wandering aimlessly | Plan each click. Cursor should move with purpose — straight lines to targets. |
