This node uses the latest Kling AI model to generate a video from a text description. It sends your prompt to a remote API and returns the generated video. The node allows you to control the video’s length, shape, quality, and even create multi-shot storyboards.

Inputs

Parameter Constraints and Limitations

• Model-specific limitations:
  • The kling-video-o1 model only supports durations of 5 or 10 seconds.
  • The kling-video-o1 model does not support audio generation.
  • The kling-video-o1 model does not support 4k resolution.
  • The kling-video-o1 model does not support storyboards.
• Storyboard constraints:
  • When storyboards are enabled, the prompt field is ignored.
  • Each storyboard requires its own prompt (1 to 512 characters) and duration.
  • The total duration of all storyboards must exactly equal the global duration parameter.
• Prompt requirements:
  • When storyboards are disabled, the prompt field is required (minimum 1 character).
  • When storyboards are enabled, the prompt field can be empty (0 characters).
