ByteDance Seedance V1 Lite — Reference-to-Video
Seedance V1 Lite Reference-to-Video is an advanced multi-reference video generation model from ByteDance that creates videos featuring subjects from your reference images. Upload up to 4 reference images of people, animals, or objects, and the model generates a coherent video with those subjects interacting based on your prompt.
Why It Stands Out
- Multi-reference support: Add up to 4 reference images to include multiple subjects in your video.
- Subject preservation: Maintains the identity and appearance of subjects from reference images.
- Prompt-guided action: Describe how subjects should interact or move in the generated video.
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Camera control: Option to fix camera position for stable, static shots.
- Flexible duration: Generate videos of varying lengths based on your needs.
- Reproducibility: Use the seed parameter to recreate exact results.

- When using multiple subjects, describe their relative positions and actions clearly.
- Fix the seed when iterating to compare different prompt variations.
Notes
