How to Use
- Upload reference images — provide 1-7 images that define the subject, identity, or style.
- Write your prompt — describe the motion, scene, and camera behavior you want.
- Set duration (optional) — choose how long the video should be.
- Choose aspect ratio — match the target platform (e.g.
9:16for vertical,16:9for landscape). - Choose resolution — use
480pfor lower cost or720pfor higher quality. - Submit — run the model and download the generated video.
Example Prompt
The person from the references walks confidently through a rainy neon-lit street at night, cinematic framing, realistic skin texture, natural hair movement, subtle camera push-in

480pcosts $0.08 per second720pcosts $0.14 per second- Each reference image adds $0.01 (1-7 images supported)
- Pricing scales linearly with
duration - Billed duration is rounded up to the next whole second
- Minimum billed duration is 1 second
- Maximum billed duration is 15 seconds
Best Use Cases
- Identity-consistent video — Keep a character or subject coherent across a clip.
- Character-driven content — Animate a person or persona defined by reference images.
- Social media content — Create stylized animated visuals for posts and promos.
- Concept visualization — Explore motion directions anchored to a defined look.
- Creative prototyping — Test reference-guided motion ideas quickly.
Pro Tips
- Use clear, high-quality reference images for better identity and style stability.
- Provide multiple references of the same subject to strengthen consistency.
- Be specific in your prompt about camera movement, subject motion, and atmosphere.
- Match
aspect_ratioto where the clip will be published. - Use
480pfor quick testing and720pfor better final-quality clips.
