Wskazówki

  • Generation time:
    • 480p: ~40-60 seconds
    • 720p: ~60-90 seconds
    • 1080p: ~90-120 seconds
    • LoRA mode adds 10-20 seconds for loading
    • Submit task, wait 60 seconds, then poll every 5 seconds
  • 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.
  • LoRA fine-tuning:
    • Load custom LoRA models for specific styles or characters
    • LoRA URL must be publicly downloadable (HuggingFace, Civitai, etc.)
    • URL should include ?download=true or similar download parameters
    • Max 3 LoRA models simultaneously
    • scale parameter controls LoRA influence, recommended: 0.5-2.0
  • Resolution selection:
    • 480p: Fast generation, for previews
    • 720p: Balanced quality and speed
    • 1080p: Highest quality, for final output
  • Duration: Supports flexible 5-20 second duration, billed per second.
  • Seed reproduction: Same seed + prompt + parameters reproduces identical results.
  • Image formats: image_urls supports JPG, PNG, WebP, max 10MB per image.
  • LoRA compatibility: Use video-trained LoRAs; image LoRAs may not work well.
Video generation takes longer than images — use callback mode for production workloads. Result URLs expire after 15 days; download important outputs promptly.
