Veo 3 character consistency: reference images and workflow in 2026
Character
consistency
If you searched for google veo 3 reference images character consistency, the useful answer is not "just write better prompts." The real answer is that Google officially supports reference-image workflows for keeping elements consistent, while UlazAI's live Veo 3.1 route currently gives you one or two frame images for tighter shot control.
Use reference images.
One or two frame images
for tighter shot control.
Google's Vertex AI documentation says Veo can use subject images to preserve appearance, and that workflow supports up to three images of a single person, character, or product. Google's October 16, 2025 Veo 3.1 guide also points to reference images for keeping characters and styles consistent across multi-shot scenes.
On UlazAI today, the live Veo 3.1 path is more practical than that broader official workflow: one image URL centers the generation around a source frame, and two image URLs let you create a first-frame to last-frame transition. That means the right next step depends on whether you want a fast studio test, a paid render path, or API details.

- Commercial fit: the next click should be studio, pricing, or docs.
- Trust: this page now distinguishes official Google capability from the current live UlazAI route.
Reference images preserve appearance
Google's Vertex AI docs say Veo can use subject images to preserve the appearance of a person, character, or product in the output video. That is the real foundation behind the query cluster this page ranks for.
Up to three subject images
The official reference-image workflow supports up to three images of a single person, character, or product. That is broader than a basic image-to-video prompt and closer to a consistency workflow.
One or two frame images today
UlazAI's live Veo 3.1 docs currently expose one or two imageUrls for frame control. Use one image to anchor the shot, or two images to drive a first-frame to last-frame transition.
What to expect from character consistency right now
This is the distinction that matters if you do not want a bait-and-switch page.
A workable character-consistency flow for UlazAI
Start from a strong source frame
Use one clear source image when the goal is to keep one character's face, styling, outfit, or silhouette stable. If the shot must transition between two controlled states, use a first frame and last frame.
Keep identity traits fixed in the prompt
Do not rewrite the character every time. Reuse the same age, clothing, hairstyle, accessories, camera distance, and tone anchors so the frame input and the text prompt are not fighting each other.
Test fast before you scale
Run the workflow in Veo 3.1 Fast first. When the identity and motion feel stable enough, then move into the paid path or the higher-quality route for production output.

What should I click next if I want actual output?
Open Veo 3.1 Studio if you want to test the workflow, pricing if you are moving into paid generations, or docs if you need the API path.
Take the clean next step
Use studio for a live test, pricing for the paid path, or docs for implementation. This page should route you forward, not trap you in vague feature copy.
