Create one natural waist-up photograph of the woman in the reference at an outdoor Paris cafe, holding a small white coffee cup. The reference sheet shows multiple views of ONE fictional woman. Preserve her face, freckles, short auburn bob, tan jacket and black top. Soft morning daylight, relaxed expression, cafe tables softly visible behind her. Exactly one person in a single continuous photograph, no collage, no panels, no text.

Animate the woman in the reference photo sitting at the outdoor cafe. She gently lifts the white coffee cup a little and smiles naturally. Keep the same face, freckles, auburn bob, tan jacket and black top throughout. Subtle hair movement in a light breeze. Locked camera, one continuous shot, no cuts, no additional people, no text.

Character consistency in practice

Same character, different scenes

AI character consistency keeps a character recognizable as the pose, outfit, or setting changes. Use an approved reference to guide each new image or video.

  1. Save a reference

    Add useful views of your character and give the reference a name.

  2. Create a new scene

    Call the saved reference in your prompt. Describe what changes, such as the setting or outfit.

  3. Check the result

    Compare the face and defining details before reusing the image or making a video.

    FAQ

    Frequently Asked Questions

    Which reference images work best?

    Choose clear, well-lit images of the same subject. Keep faces unobstructed and product details visible. Put your main reference first and avoid mixing different people unless you want them together. Use only images you have permission to upload.

    Will the character look exactly the same every time?

    References help preserve identity, but results can still vary. Large changes in pose, lighting, clothing or camera angle can affect facial details. Describe what must stay the same and what should change, then review each result before using it.

    Can I close the page while a generation is running?

    Yes. Once your request is accepted and a task is created, processing continues on the backend. Return to Generation History to check its status and saved output. If the provider or file transfer is delayed, recovery can take longer; keeping the tab open is not required.

    Where are my images stored, and can I delete them?

    Saved outputs remain in Generation History until you delete the generation or close your account. Manage reference assets in your library. Files still used by another asset or generation are retained until those references are removed. Anyone with a media URL may be able to view that file. Third-party AI providers have their own retention policies.

    Can I use the results commercially?

    Commercial use is subject to our Terms of Service, the model provider’s terms and the rights attached to your inputs. Make sure you have permission to use any people, brands or protected content. Outputs may not be unique; CharaSync does not guarantee exclusive rights or that every result is suitable for commercial use.
