# KlingVideoNode - ComfyUI Built-in Node Documentation

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

This node generates videos using the Kling V3 model. It supports text-to-video mode, where a video is created from a text description, and image-to-video mode, where an existing image is animated. It also offers advanced features like creating multi-segment videos with individual prompts for each part (storyboards) and optionally generating accompanying audio.

## Inputs

| Parameter            | Description                                                                                                                                                                                         | Data Type | Required | Range                                                                                                                                                 |
| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| `multi_shot`         | Controls whether to generate a single video or a series of segments with individual prompts and durations. When not "disabled," additional inputs for each storyboard's prompt and duration appear. | COMBO     | Yes      | `"disabled"`<br />`"1 storyboard"`<br />`"2 storyboards"`<br />`"3 storyboards"`<br />`"4 storyboards"`<br />`"5 storyboards"`<br />`"6 storyboards"` |
| `generate_audio`     | When enabled, the node will generate audio for the video. Default is True.                                                                                                                          | BOOLEAN   | Yes      | True / False                                                                                                                                          |
| `model`              | The model and its associated settings. Selecting this option reveals the `resolution` and `aspect_ratio` sub-parameters.                                                                            | COMBO     | Yes      | `"kling-v3"`                                                                                                                                          |
| `model.resolution`   | The resolution for the generated video.                                                                                                                                                             | COMBO     | Yes      | `"4k"`<br />`"1080p"`<br />`"720p"`                                                                                                                   |
| `model.aspect_ratio` | The aspect ratio for the generated video. This setting is ignored when an image is provided for `start_frame` (image-to-video mode).                                                                | COMBO     | Yes      | `"16:9"`<br />`"9:16"`<br />`"1:1"`                                                                                                                   |
| `seed`               | A seed value for generation. Changing this value will cause the node to re-run, but results are non-deterministic regardless of seed. Default is 0.                                                 | INT       | Yes      | 0 to 2147483647                                                                                                                                       |
| `start_frame`        | Optional start frame image. When connected, switches to image-to-video mode.                                                                                                                        | IMAGE     | No       | -                                                                                                                                                     |

**Inputs for `multi_shot` mode:**

* When `multi_shot` is set to **"disabled"**, the following inputs appear:
  * `prompt` (STRING): The main text description for the video. Must be between 1 and 2500 characters.
  * `negative_prompt` (STRING): Text describing what should not appear in the video.
  * `duration` (INT): The length of the video in seconds. Must be between 3 and 15. Default is 5.
* When `multi_shot` is set to a storyboard option (e.g., `"3 storyboards"`), inputs for each storyboard segment appear (e.g., `storyboard_1_prompt`, `storyboard_1_duration`). Each storyboard prompt must be between 1 and 512 characters. The **total sum of all storyboard durations** must be between 3 and 15 seconds.

**Constraints:**

* The node operates in **text-to-video** mode when `start_frame` is not connected. It uses the `model.aspect_ratio` setting in this mode.
* The node operates in **image-to-video** mode when `start_frame` is connected. The `model.aspect_ratio` setting is ignored. The input image must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1.
* In storyboard mode (`multi_shot` not "disabled"), the main `prompt` and `negative_prompt` inputs are hidden and not used.

## Outputs

| Output Name | Description               | Data Type |
| ----------- | ------------------------- | --------- |
| `video`     | The generated video file. | VIDEO     |
