Consejos

  • Generation time:
    • 5-second video: ~50-70 seconds
    • 10-second video: ~80-100 seconds
    • Submit task, wait 50 seconds, then poll every 5 seconds
  • Audio generation: Kling 2.6’s key feature is audio generation:
    • sound: true: Auto-generates matching ambient sounds and background music
    • sound: false: Generates silent video
    • Describe sound effects in prompt for better audio (e.g., “birds chirping”, “water flowing”)
  • Callback mode: Video generation takes time, strongly recommend using callback mode.
  • Video expiration: Result URLs are valid for 15 days. Download promptly.
  • Content moderation: Prompts must comply with content safety guidelines.
  • Aspect ratio selection:
    • 1:1: Square, for social media (default)
    • 16:9: Landscape, for traditional video platforms
    • 9:16: Portrait, for short video platforms
  • Image formats: image_urls supports JPG, PNG, WebP, max 10MB per image.
  • Prompt tips: Describe both visual and audio effects in prompts for better audio-video synchronization.
Video generation takes longer than images — use callback mode for production workloads. Result URLs expire after 15 days; download important outputs promptly.
