How to Keep Character Consistency in Veo 3 — Guide (2025)

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 — 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.

🔁 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"

…Veo might generate a different-looking man every time.

🧰 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.
