# Character Sheet Workflow
|
|
|
|
## Overview
|
|
|
|
Character Sheets are a key tool for maintaining character consistency in MV production. By generating standardized character reference images, you ensure uniform character appearance across all subsequent scenes.
|
|
|
|
## Character Sheet Types
|
|
|
|
### 1. Turnaround Sheet
|
|
|
|
Shows the character from multiple angles: front, 3/4 view, side, and back.
|
|
|
|
```
|
|
Prompt template:
|
|
"Character turnaround sheet of [character description], showing front view, 3/4 view, side view, and back view. [clothing description]. Clean white background, consistent lighting, full body, character design reference sheet, anime/realistic style."
|
|
```
|
|
|
|
### 2. Expression Sheet
|
|
|
|
Shows the character in different emotional states.
|
|
|
|
```
|
|
Prompt template:
|
|
"Expression sheet of [character description], showing 6 different emotions: neutral, happy, sad, angry, surprised, contemplative. Same angle (front-facing), consistent lighting, bust shot, clean layout, character reference sheet."
|
|
```
|
|
|
|
### 3. Pose Sheet
|
|
|
|
Shows the character in different action poses.
|
|
|
|
```
|
|
Prompt template:
|
|
"Pose reference sheet of [character description] in [clothing description], showing 4 dynamic poses: standing, walking, sitting, [specific action]. Full body, clean white background, consistent proportions, action reference sheet."
|
|
```
|
|
|
|
## Workflow
|
|
|
|
### Step 1: Define Character Description
|
|
|
|
Write a detailed character text description including:
|
|
- **Body type**: Height, build (slim, athletic, curvy...)
|
|
- **Facial features**: Face shape, eye color, hairstyle and hair color
|
|
- **Clothing**: Detailed outfit description
|
|
- **Aura**: Overall impression/vibe
|
|
|
|
Example:
|
|
```
|
|
A young Chinese woman in her mid-20s with delicate features. She has long straight
|
|
black hair reaching her waist, almond-shaped dark brown eyes, and fair skin.
|
|
She wears a modern hanfu-inspired outfit: a white silk top with subtle floral
|
|
embroidery and a flowing navy blue pleated skirt. Elegant and ethereal presence.
|
|
```
|
|
|
|
### Step 2: Select Generation Model
|
|
|
|
| Style Requirement | Recommended Model | Reason |
|
|
|-------------------|-------------------|--------|
|
|
| Realistic characters | Kling (face mode) | Strongest facial consistency |
|
|
| Anime characters | Midjourney (--niji 7) | Highest anime quality |
|
|
| Concept design | Gemini / OpenAI | Fast iteration |
|
|
| Stylized | Kontext | Can convert from photos to style |
|
|
|
|
### Step 3: Generate Character Sheets
|
|
|
|
1. **Generate the front-facing base image first**:
|
|
```
|
|
"Portrait of [character description], front-facing, neutral expression, soft studio lighting,
|
|
clean background, character reference, high detail"
|
|
```
|
|
|
|
2. **Using the base image as reference, generate turnaround sheet**:
|
|
```
|
|
image_paths: [base image]
|
|
prompt: "Character turnaround sheet based on this character..."
|
|
```
|
|
|
|
3. **Generate expression sheet**:
|
|
```
|
|
image_paths: [base image]
|
|
prompt: "Expression sheet of this same character..."
|
|
```
|
|
|
|
### Step 4: Verify Consistency
|
|
|
|
After generation, check:
|
|
- [ ] Are facial features consistent across all angles?
|
|
- [ ] Is the hairstyle logical from all angles?
|
|
- [ ] Are clothing details maintained consistently?
|
|
- [ ] Are body proportions stable?
|
|
- [ ] Is the overall style unified?
|
|
|
|
Fix inconsistencies using Kontext or Kling.
|
|
|
|
### Step 5: Output for Downstream Use
|
|
|
|
Character sheet applications:
|
|
- **Video first frame generation**: Use Kling face mode + scene description
|
|
- **Storyboard generation**: Use as character reference images
|
|
- **Lip sync**: Provide front-facing close-up as first frame
|
|
|
|
## Photorealistic Character Design
|
|
|
|
When "real-person photo" quality is needed for character design:
|
|
|
|
```
|
|
Prompt template:
|
|
"Professional photography headshot of [character description], [expression],
|
|
shot on Canon EOS R5, 85mm f/1.4 lens, natural window light,
|
|
clean neutral background, magazine quality portrait, photorealistic,
|
|
8K detail, skin texture visible, catchlight in eyes."
|
|
```
|
|
|
|
Key elements:
|
|
- Specify camera and lens parameters to increase realism
|
|
- Describe light direction and quality
|
|
- Mention skin texture and catchlight
|
|
- Use photography terminology rather than painting terminology
|
|
|
|
## MV Character Design Best Practices
|
|
|
|
1. **Prepare for lip sync**: Front-facing character close-ups should have mouth slightly open or in a speech-ready state
|
|
2. **Multiple outfits**: If the MV has scene changes, prepare corresponding outfit versions for each scene
|
|
3. **Emotional range**: MVs require rich expressions — ensure the expression sheet covers all emotions in the song
|
|
4. **First-frame friendly**: Character image composition should work as a video first frame (leave room for motion)
|
|
5. **Save all prompts**: Record the prompt used for each generated image for easy reuse and adjustment
