Vidu Reference to Video Q1
Transform your reference images into dynamic videos with consistent subjects and environments. Our advanced Multi-Entity Consistency technology ensures characters, objects, and scenes maintain their visual identity throughout the video.
Features
Reference to Video Q1
Features
Multi-Entity Consistency
- Maintains visual identity of characters and objects
- Preserves style and appearance across frames
- Supports multiple reference subjects
Flexible Input
- Accepts 1-3 reference images
- Supports various aspect ratios (16:9, 9:16, 1:1)
- Adjustable movement amplitude
Requirements
Images
- Number: 1-3 reference images
- Format: PNG, JPEG, JPG, WebP
- Size: Minimum 128x128 pixels
- Aspect ratio: Less than 1:4 or 4:1
- File size: Maximum 50MB per image
Prompt
- Maximum length: 1500 characters
- Should describe desired motion and scene
Best Practices
- Use clear, high-quality reference images
- Provide detailed prompts for better results
- Consider scene composition in reference images
- Test different movement amplitudes for optimal output
Effect Boundaries
- Best results with clear, well-lit reference images
- Movement amplitude affects transition smoothness
- Complex scenes may require multiple reference images
