Character Creation

Design a character once. Reuse it forever.

A character is: a name, a personality, a visual identity (portrait image), and a voice archetype. Every video in a series pulls from the same config so the character stays consistent across 100 episodes.

Characters are stored at ~/clawd/characters/<slug>/.

---

Step 1: Define the Character

Before touching Nano Banana, answer these questions:

Field	Description	Example
Name	Character's on-screen name	"Max", "Dr. Erica", "The Analyst"
Slug	Filesystem-safe ID	max, dr-erica, the-analyst
Platform	Primary target	TikTok, Reels, Shorts
Niche / Topic	What does this character talk about?	Investing, personal finance, crypto
Personality	3 adjectives max	Confident, dry, contrarian
Speech style	How they talk	Short sentences. No hedging. Uses "here's the thing:" a lot.
Voice archetype	For ElevenLabs selection	Deep male, mid-range female, energetic young male
Visual style	Overall aesthetic	Photorealistic, 3D animated, illustrated
Appearance	Age, ethnicity, clothing, setting	35yo, business casual, minimalist office background

Save answers — you'll use them in every step.

Step 2: Generate the Portrait

Two images required: portrait (for thumbnails, branding) and face reference (for InfiniteTalk consistency).

Portrait (9:16 for TikTok/Reels)

uv run ~/clawd/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "<appearance description>, looking directly at camera, confident expression, <visual style>, professional lighting, clean background" \
  --filename "~/clawd/characters/<slug>/portrait-$(date +%Y-%m-%d).png" \
  --aspect-ratio 9:16 \
  --resolution 2K \
  --thinking high

Face Reference (1:1 for InfiniteTalk)

uv run ~/clawd/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "<appearance description>, extreme close-up headshot, neutral expression, facing forward, <visual style>, studio lighting, white background" \
  --filename "~/clawd/characters/<slug>/face-ref-$(date +%Y-%m-%d).png" \
  --aspect-ratio 1:1 \
  --resolution 2K \
  --thinking high

Iteration

• Start at --resolution 512 for fast drafts. Lock the look first.
• Once approved, regenerate at 2K with --thinking high.
• If 80% is right, edit: --input-image the draft + prompt the specific fix.
• For consistency across future regenerations: always pass the approved face reference as --input-image with "Keep the person's facial features exactly the same as the input image".

Step 3: Save the Config

Create ~/clawd/characters/<slug>/config.json:

{
  "name": "Max",
  "slug": "max",
  "platform": "TikTok",
  "niche": "Investing / Stock Market",
  "personality": ["confident", "dry", "contrarian"],
  "speech_style": "Short punchy sentences. No hedging. Calls out conventional wisdom. Uses 'here's the thing:' as a transition.",
  "voice_archetype": "Deep male, 35-45yo, measured pace, slight edge",
  "elevenlabs_voice_id": "",
  "visual_style": "Photorealistic",
  "appearance": "35yo male, sharp jawline, business casual (navy blazer, no tie), minimalist modern office background, warm key light from left",
  "portrait": "portrait-2026-03-03.png",
  "face_ref": "face-ref-2026-03-03.png",
  "created": "2026-03-03",
  "accounts": {
    "tiktok": "",
    "reels": "",
    "shorts": ""
  }
}

Fill in elevenlabs_voice_id after selecting/cloning the voice in ElevenLabs. Fill in accounts with platform handles once set up.

Step 4: Verify Consistency

Before the character is production-ready, generate 3 test images using the face reference as input and verify:

• Same facial features across all 3
• Expression changes work (neutral, smile, serious)
• The character reads clearly at thumbnail size (small screen test)

If consistency breaks: pass 2-3 approved reference images simultaneously via comma-separated --input-image.

When to Create a New Character

• New account on a new platform with a different niche or tone
• Series concept that needs a visually distinct persona
• A/B testing two character styles on the same niche

Don't create a new character just because you're starting a new series. If the niche and platform match, reuse the existing character — that's the whole point.

Downstream Usage

Once a character is created:

• Scripts → content-strategy skill (Video Series section) writes the episode scripts in the character's voice
• Audio → ElevenLabs, using elevenlabs_voice_id from config
• Video → InfiniteTalk, using face_ref image + ElevenLabs audio
• Scheduling → upload the output MP4 to your platform of choice
