Tips

Generation time:
- 5-second video: ~30-45 seconds
- 10-second video: ~45-60 seconds
- Submit task, wait 30 seconds, then poll every 5 seconds
Turbo advantage: Faster generation and better value compared to standard version, ideal for batch generation.
Callback mode: Recommend using callback mode to avoid frequent polling.
Video expiration: Result URLs are valid for 15 days. Download promptly.
Content moderation: Prompts must comply with content safety guidelines.
End frame control: image-to-video mode supports 2 images:
- 1st image: Video start frame
- 2nd image: Video end frame
- Enables precise start/end control, ideal for transition animations
Negative prompt: Use negative_prompt to avoid blur, jitter, and other unwanted effects.
CFG Scale:
- 0.3-0.5: More creative freedom
- 0.6-0.8: Moderate adherence to prompt
- 0.9-1.0: Strict adherence, may lose flexibility
Image formats: image_urls supports JPG, PNG, WebP, max 10MB per image.
