# Promo Director Skill

Generate professional promo videos for social media from mastered audio. Creates 15-second vertical videos (9:16, 1080x1920) optimized for Instagram Reels, Twitter, and TikTok.

## Purpose

After mastering audio, generate promotional videos that combine:
- Album artwork
- Audio waveform visualization (9 styles available)
- Track title + artist name
- Automatic color scheme extracted from artwork
- Intelligent segment selection (finds the most energetic 15 seconds)

## When to Use

- After mastering complete, before release
- User says "generate promo videos" or "create promo videos for [album]"
- When album has mastered audio + artwork ready

## Position in Workflow

```
Generate → Master → **[Promo Videos]** → Release
```

Optional step between mastering-engineer and release-director.

## Workflow

### 1. Setup Verification

**Check ffmpeg:**
```bash
ffmpeg -filters | grep showwaves
```

Required filters: `showwaves`, `showfreqs`, `drawtext`, `gblur`

If missing:
```
Error: ffmpeg not found or missing required filters

Install ffmpeg:
  macOS: brew install ffmpeg
  Linux: apt install ffmpeg

After installing, run this command again.
```

**Check Python dependencies:**

Call `get_python_command()` to verify the venv exists. If `venv_exists` is false, show the warning and suggest `/bitwize-music:setup`.

### 2. Album Detection

**Resolve audio path via MCP:**

Call `resolve_path("audio", album_slug)` — returns the full audio directory path including artist folder.

Example result: `~/bitwize-music/audio/artists/bitwize/albums/electronic/sample-album/`

**Verify contents:**
- ✓ Mastered audio files (.wav, .mp3, .flac, .m4a)
- ✓ Album artwork (album.png or album.jpg)

If artwork missing:
```
Error: No album artwork found in {audio_root}/artists/{artist}/albums/{genre}/{album}/

Expected: album.png or album.jpg

Options:
  1. Use /bitwize-music:import-art to place artwork
  2. Specify path manually: --artwork /path/to/art.png

Which option?
```

### 3. User Preferences

**Check config defaults first:**

Read `promotion` section from `~/.bitwize-music/config.yaml` for defaults:
- `promotion.default_style` - Default visualization style
- `promotion.duration` - Default clip duration
- `promotion.include_sampler` - Whether to generate album sampler by default
- `promotion.sampler_clip_duration` - Seconds per track in sampler

If config section doesn't exist, use built-in defaults (pulse, 15s, sampler enabled, 12s clips).

**Ask: What to generate?**

Options (default from config or "both"):
1. Individual track promos (15s each) + Album sampler (all tracks)
2. Individual track promos only
3. Album sampler only

**Ask: Visualization style?**

Default from `promotion.default_style` or `pulse` if not set.

| Style | Best For | Description |
|-------|----------|-------------|
| `pulse` | Electronic, hip-hop | Oscilloscope/EKG style with heavy glow (default) |
| `bars` | Pop, rock | Fast reactive spectrum bars |
| `line` | Acoustic, folk | Classic clean waveform |
| `mirror` | Ambient, chill | Mirrored waveform with symmetry |
| `mountains` | EDM, bass-heavy | Dual-channel spectrum (looks like mountains) |
| `colorwave` | Indie, alternative | Clean waveform with subtle glow |
| `neon` | Synthwave, 80s | Sharp waveform with punchy neon glow |
| `dual` | Experimental | Two separate waveforms (dominant + complementary colors) |
| `circular` | Abstract, experimental | Vectorscope (wild circular patterns) |

**Default recommendation:**
- Electronic/Hip-Hop → `pulse`
- Rock/Pop → `bars`
- Folk/Acoustic → `line`
- Ambient/Chill → `mirror`
