🚀 How to Use

  1. Write your prompt describing the scene, lighting, or action. Example: “A cute kitten stretches lazily in the morning sunlight, soft fur glowing.”
  2. (Optional) Upload a reference image to fix the composition.
  3. Select your duration (6 s or 10 s).
  4. Enable Prompt Expansion for improved scene coherence and safety.
  5. Check Go Fast mode to prioritize speed.
  6. Click Run and receive your generated video in under a minute.

💡 Pro Tips

  • Keep prompts concise — the model auto-expands them intelligently.
  • Use lighting cues like sunset, studio light, or cinematic glow for richer output.
  • For social content, try 6 s mode for faster delivery.
  • For detailed storytelling or dynamic motion, use 10 s.
  • Combine clips to create longer edits using consistent camera language.

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringNo-The positive prompt for the generation.
imagestringYes-The model generates video with the picture passed in as the first frame.Base64 encoded strings in data:image/jpeg; base64,{data} format for incoming images, or URLs accessible via the public network. The uploaded image needs to meet the following conditions: Format is JPG/JPEG/PNG; The aspect ratio is greater than 2:5 and less than 5:2; Short side pixels greater than 300px; The image file size cannot exceed 20MB.
