Veo 3 Character Consistency with Reference Images
One of the biggest challenges with AI video generation is keeping the same character consistent across scenes. With Google Veo 3, each prompt creates a new video β and without control, your character might look different every time.
That's why we built the Character Lock Tool inside Ulazai.com. With it, you can generate multi-scene videos where the same character appears in every scene, with consistent clothing, face, and features.
π The Problem: No Character Memory in Veo 3
Google Veo 3 is incredibly powerful, but it doesn't have character memory. That means each time you generate a prompt like:
"A man walks through the jungle with a torch at night"
β¦Veo might generate a different-looking man every time.
π§° The Solution: Ulazai's Character Prompt Tool
Ulazai lets you define a consistent character base that's injected automatically into all your prompts behind the scenes.
For example, instead of writing separate prompts like:
- "A man walks through a jungle at night"
- "A man finds an ancient temple"
- "A man escapes through the vines"
You just define your character once:
"A tall man with a green jacket, brown leather boots, short black beard, and scar over his left eye."
Ulazai adds this description into every prompt, giving you visual consistency.
π¬ How to Use the Character Tool in Ulazai
- Go to ulazai.com/video
- Describe your main character in detail (appearance, clothing, age, style)
- Write your scene prompts without repeating the character
- Ulazai combines both and sends perfect prompts to Veo 3
Result: The same character appears across all generated videos.
π₯ Multi-Scene Use Cases
- Storytelling (e.g. 'A girl's journey through space')
- Product explainers with the same host
- Educational content featuring a recurring teacher or narrator
- Brand mascot consistency across campaigns
β¨ Tips for Better Results
- Use specific physical traits and accessories
- Stay consistent in style (cinematic, realistic, anime)
- Stick to a color scheme or outfit
- Use vertical (9:16) for TikTok and Shorts
π¦ Bonus: Reusable Character Templates
Ulazai allows you to save your character as a template and re-use it in future videos. Perfect for series or ongoing storylines.
