Complete AI Short Drama Character Design Guide
What you will learn
- Why character consistency becomes the core challenge in AI short drama
- What each of the six reference views is meant to lock
- How to choose a model and write more stable prompts
- When to upload custom images, use image-to-image, or configure voice cloning
Character design is not about getting one nice image and moving on. The goal is to lock visual anchors and voice anchors early, so downstream storyboard and video work stays stable.
Typical failures
The same written prompt produces a different face shape every time
Hairstyle or clothing quietly changes between shots
The emotion is correct, but the person no longer looks like the same character
1. What character consistency means
Character consistency means the same person keeps recognizable facial structure, hairstyle, outfit, and overall presence across shots, emotions, and poses. It is one of the most important foundations of an AI short drama pipeline.
2. Why characters drift so easily
3. The six-view reference system
What each reference view does
| Angle | Purpose | Best for |
|---|---|---|
| Front full body | Locks body proportion, silhouette, and outfit ratio | Wide shots and action scenes |
| Front half body | Locks facial features and upper-body details | Dialogue and frontal shots |
| Side view | Locks profile shape, nose line, and hairstyle layers | Side-angle shots |
| Happy | Locks positive emotional expression style | Light or uplifting beats |
| Angry | Locks high-tension conflict expression | Arguments and climactic moments |
| Sad | Locks low-emotion eyes and facial mood | Emotional low points |
4. Reference generation workflow
If only one angle is weak, do not restart the full set. Regenerate the single image first or replace that angle with a custom upload.
5. Model selection
| Model | Strength | Best for |
|---|---|---|
| Tongyi Wanxiang | Stable, general-purpose, forgiving | Best default for most styles |
| Doubao | Richer detail and stronger realism | Realistic, Chinese animation, and texture-heavy roles |
| Kling | More variation and stronger stylization | Highly stylized or visually aggressive projects |
Reference generation currently costs 2 credits per run regardless of model.
⚠️ Important：Keep one character on one model from start to finish. Mixing models is one of the fastest ways to create style drift.
6. Prompt writing tips
Prompt template
✅ Good prompt
A woman around 25, long straight black hair to the waist, willow-shaped brows, almond eyes, white office suit, sharp and capable presence.
❌ Weak prompt
A pretty girl
Hairstyle ideas
- Long straight hair
- Wavy hair
- High ponytail
- Short bob
- Slicked-back hair
Facial detail ideas
- Willow brows
- Straight brows
- Almond eyes
- Phoenix eyes
- Dimples
- Beauty mark
Outfit ideas
- Office wear
- Casual wear
- Sportswear
- Hanfu
- Armor
- Court dress
7. AI prompt optimization
✅ The best workflow is usually writing the base prompt yourself, then using AI to complete missing detail instead of delegating everything.
8. Best practices
- Make primary characters clearly different from each other instead of writing vague profiles that blur together.
- Keep outfits stable and avoid frequent costume changes inside a short drama.
- Give each character 1-2 signature traits such as a ribbon, glasses, or a necklace.
- If a reference image contains defects, regenerate immediately instead of carrying the flaw forward.
9. Common traps
Prompt is too short
Issue：Prompts like "handsome man" or "pretty girl" leave too much visual space for the model to improvise.
Fix：Provide at least five clear visual and outfit traits.
Words are too vague
Issue：Words like "stylish" or "beautiful" do not create stable visual anchors.
Fix：Use concrete details such as "double eyelids, large eyes, black leather jacket".
Models are mixed
Issue：Some views are generated with Tongyi and others with Kling, so the style no longer matches.
Fix：Use one model for one character all the way through.
Characters dress too similarly
Issue：The model cannot reliably separate people if their silhouettes and colors are too close.
Fix：Separate them through color, material, and outfit shape.
Flawed reference images are accepted
Issue：Extra hands, broken accessories, or warped faces often propagate into later outputs.
Fix：Replace or regenerate flawed references immediately.
10. Custom image upload
Best use cases
- You already have character sheets
- The automatic result is not good enough
- You need a specific real-person or branded look
Upload requirements
| Item | Guidance |
|---|---|
| Format | JPG / PNG |
| Resolution | 1024x1024 or higher is recommended |
| Background | Solid or simple backgrounds work best |
| Quantity | You can replace any 1 to 6 reference views |
Notes
- Uploaded images should match the project art style
- Different angles must still depict the same character
- Make sure the assets are cleared for commercial use
11. Image-to-image mode
Upload one reference image and let AI generate a new character image while preserving the core style or composition cues.
When to use it
- You have concept art or sketches that need a cleaner redraw
- You want to preserve a very specific visual style
- You imported character art from another tool and need style unification
✅ The reference image should already be close to the project style, otherwise style conflicts become very visible.
12. Character voice setup
Common preset voices
| Voice | Feature | Best for |
|---|---|---|
| Sweet female | Bright and soft | School, young, or cute characters |
| Mature female | Calm and composed | Professional or queen-like roles |
| Sunny male | Clear and lively | Teen and young adult roles |
| Deep male | Low and textured | Powerful or mature male roles |
| Child voice | Light and youthful | Child characters |
Voice cloning
- The system provides sample reading text, and 10 to 30 seconds is the recommended recording range.
- You can preview the recording before applying it.
- Uploading an audio file longer than 5 seconds is also supported.
✅ Voice cloning is currently a 0-credit feature, so you can refine it repeatedly.
Cloned voices support rename, delete, and batch delete.
13. Batch generation and progress
- Multiple character reference sets can be generated in parallel
- The progress panel shows the state of each character
- If only some tasks fail, you can retry them individually
FAQ
Q: What should I do if a character still looks inconsistent across storyboard shots?
Make sure all six views are locked, strengthen the character anchors, and reduce extreme visual shifts between shots.
Q: Can I use real human photos directly?
Yes, but you need proper portrait rights and should verify whether the photo style matches the project style. It usually works best for realistic projects.
Q: Is there a limit on how many characters I can have?
There is no hard technical cap, but 2 to 4 core characters is usually the most stable range for short-form work.
Q: How can I improve voice clone quality?
Record in a quiet environment, keep the delivery natural, and stay close to 30 seconds for better stability.
