Maintain Character Consistency with Multi-Input Reasoning
Keep characters consistent by providing photo references in a single multimodal prompt.
Upload a character reference photo alongside your text description to Gemini Omni Flash. The model's unified multimodal reasoning ensures that faces and clothing remain consistent across generated clips.
The Scenario
You are building a multi-shot video production and need the main character to look exactly the same across different scenes and background environments.
Before & after
Maintaining character appearances usually requires complex 'Seed' management or Photoshop post-processing to fix faces, taking 45 minutes to 2 hours for a single short scene.
With Gemini Omni Flash, you provide the reference image and the script in one prompt; the model 'reasons' across both to keep the character consistent in 5 minutes.
The Prompt
Input: [UPLOAD_CHARACTER_IMAGE] + [UPLOAD_SETTING_IMAGE] Prompt: "Using the character from the first image and the setting from the second, generate a video of this character [ACTION DESCRIPTION]. Ensure clothing and facial features remain identical to the reference."
The 'Omni' architecture processes text, images, and video in a single pass, which is significantly more effective for character consistency than models that process signals separately.
