KlingOmniProImageToVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

This node uses the Kling AI model to generate a video based on a text prompt and up to seven reference images. It lets you control the video’s aspect ratio, duration, and resolution, and optionally use storyboards or generate audio. The node sends the request to an external API and returns the generated video.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
`model_name`	The specific Kling model to use for video generation (default: `"kling-v3-omni"`).	COMBO	Yes	`"kling-v3-omni"` `"kling-video-o1"`
`prompt`	A text prompt describing the video content. This can include both positive and negative descriptions. Ignored when storyboards are enabled. Placeholders such as `@image` or `@video` (optionally numbered) are automatically converted to the API-compatible format. Must be between 1 and 2500 characters (can be empty when storyboards are enabled).	STRING	Yes	1 to 2500 characters
`aspect_ratio`	The desired aspect ratio for the generated video.	COMBO	Yes	`"16:9"` `"9:16"` `"1:1"`
`duration`	The length of the video in seconds, adjusted with a slider (default: 5).	INT	Yes	3 to 15
`reference_images`	Up to 7 reference images. Each image must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1.	IMAGE	Yes	1 to 7 images
`resolution`	The output resolution of the video (default: `"1080p"`).	COMBO	No	`"4k"` `"1080p"` `"720p"`
`storyboards`	Generate a series of video segments with individual prompts and durations. Only supported for `kling-v3-omni`. When enabled, the global `prompt` is ignored, and the total duration of all storyboard segments must equal the global `duration` (default: `"disabled"`).	DYNAMIC_COMBO	No	`"disabled"` `"1 storyboard"` `"2 storyboards"` `"3 storyboards"` `"4 storyboards"` `"5 storyboards"` `"6 storyboards"`
`generate_audio`	Generate audio for the video. Only supported for `kling-v3-omni` (default: false).	BOOLEAN	No	`true` `false`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 0).	INT	No	0 to 2147483647

Storyboard Inputs

When storyboards is enabled, the following inputs appear for each selected storyboard segment. N ranges from 1 up to the selected number of storyboards.

Parameter	Description	Data Type	Required	Range
`storyboard_N_prompt`	Prompt for storyboard segment N. Max 512 characters.	STRING	Yes	1 to 512 characters
`storyboard_N_duration`	Duration for storyboard segment N in seconds (default: 4).	INT	Yes	1 to 15

Note: The reference_images input accepts a maximum of 7 images. If more are provided, the node raises an error. Each image is validated for minimum dimensions and aspect ratio. Model-specific constraints:

kling-video-o1 does not support durations greater than 10 seconds.
kling-video-o1 does not support audio generation.
kling-video-o1 does not support 4k resolution.
kling-video-o1 does not support storyboards.

Outputs

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