# KlingOmniProTextToVideoNode - ComfyUI Built-in Node Documentation

> Complete documentation for the KlingOmniProTextToVideoNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/KlingOmniProTextToVideoNode/en.md)

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.

### 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).
