}Vidu Q3 Mix R2V
[Core Function] Vidu Q3 Mix R2V is a mixed-style reference-to-video generation model. [Strengths] It excels at generating highly consistent character videos by synthesizing and blending features from multiple reference images (up to 7) based on a text prompt. [Best For] Highly recommended for: maintaining strict character consistency across different styles, generating videos of a specific subject in entirely new environments, and blending concepts from multiple reference images. [Limitations] Do NOT use this model if you just want to animate a single image as is (use standard I2V). This model focuses on extracting character/style features and generating new content. [Routing] Use this when the user provides reference images of a character/subject and wants a video of them doing a specific new action from a text prompt, prioritizing mixed-style consistency.
