How to Use

  1. Prepare your reference images — gather the subject and/or background images you want to use.

  4. Set quality — choose resolution based on your quality and speed requirements.
  5. Adjust duration — set video length up to 15 seconds.
  6. Configure audio (optional) — enable or disable synchronized audio generation.
  7. Run — submit and download your video.

Best Use Cases

  • Character Animation — Generate videos featuring specific people or characters with visual consistency.
  • Product Videos — Keep product appearance consistent throughout the generated video.
  • Brand Content — Maintain brand identity elements across video generations.
  • Multi-character Scenes — Include multiple distinct subjects in a single video.
  • Custom Backgrounds — Fix a specific environment as the video backdrop.

Pro Tips

  • Assign ref_name to each reference and mention them in your prompt for better accuracy.
  • Use type: "subject" for characters and objects, type: "background" for environments.
  • Use clean, high-quality images with clear subjects for the best consistency results.
  • Limit references to the most essential subjects — too many may reduce quality.
  • Ensure image URLs are publicly accessible; base64 is supported for private assets.
