Vidu AI ensures role consistency through three technologies:
- multi-entity recognition: After uploading character images, the AI extracts key elements such as facial features, clothing, etc. and keeps them uniform across all frames of the video.
- Reference Raw Video Mode: When the user provides the first and last frames, the system analyzes the action path and automatically fills the intermediate frames to avoid sudden changes in the image.
- Dynamic binding technology: For complex movements (e.g., turns), AI builds skeletal models so that appendages such as clothing and hairstyles move naturally with the subject.
In practice, it is recommended to uploadClear front and side character drawings(Resolution ≥ 720p), avoiding blockage or bright light to interfere with the recognition. If any deviation is found, it can be corrected by adjusting the descriptor (e.g. "keep the red dress") or re-uploading the reference image.
