Bytedance Seedance V1 Lite Reference To Video

Playground

Seedance v1 Lite converts 1 to 4 reference images into high-quality videos with reference-to-video image-to-video generation. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Seedance V1 Lite Reference-to-Video is an advanced multi-reference video generation model from 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.

Parameters

How to Use

1. Write a prompt describing the action and scene you want. Use the Prompt Enhancer for AI-assisted optimization.
2. Add reference images — upload up to 4 images of subjects (people, animals, objects) to include in the video.
3. Set duration — choose how long you want the video to be.
4. Enable camera_fixed (optional) — check this for a stable, static camera shot.
5. Set a seed (optional) for reproducible results.
6. Click Run and wait for your video to generate.
7. Preview and download the result.

Best Use Cases

• Character Animation — Animate portraits or character images in custom scenes.
• Pet Videos — Create fun videos featuring your pets in imaginative scenarios.
• Social Media Content — Generate engaging videos with multiple subjects interacting.
• Storytelling — Bring characters together in narrative video clips.
• Marketing & Advertising — Create product videos featuring specific items or mascots.
• Creative Projects — Combine different subjects in unique, creative compositions.

Total cost = $0.18 × (duration / 5)

Pro Tips for Best Quality

• Use clear, high-quality reference images with subjects well-visible.
• For best results, use front-facing or 3/4 angle reference photos.
• Be specific in your prompt about how subjects should interact.
• Enable camera_fixed for professional-looking static shots.
• When using multiple subjects, describe their relative positions and actions clearly.
• Fix the seed when iterating to compare different prompt variations.

Notes

• Maximum of 4 reference images per generation.
• Ensure uploaded image URLs are publicly accessible.
• Processing time varies based on duration and current queue load.
• Please ensure your content complies with usage guidelines.
