KlingOmniProVideoToVideoNode - ComfyUI Built-in Node Documentation

This node uses the Kling AI model to generate a new video based on an input video and optional reference images. You provide a text prompt describing the desired content, and the node transforms the reference video accordingly. It can also incorporate up to four additional reference images to guide the style and content of the output.

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.	STRING	Yes	N/A
`aspect_ratio`	The desired aspect ratio for the generated video.	COMBO	Yes	`"16:9"` `"9:16"` `"1:1"`
`duration`	The length of the generated video in seconds (default: 3).	INT	Yes	3 to 10
`reference_video`	Video to use as a reference.	VIDEO	Yes	N/A
`keep_original_sound`	Determines if the audio from the reference video is kept in the output (default: True).	BOOLEAN	Yes	N/A
`reference_images`	Up to 4 additional reference images.	IMAGE	No	N/A
`resolution`	The resolution for the generated video (default: “1080p”).	COMBO	No	`"1080p"` `"720p"`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 0).	INT	No	0 to 2147483647

Parameter Constraints:

The prompt must be between 1 and 2500 characters long.
The reference_video must be between 3.0 and 10.05 seconds in duration.
The reference_video must have dimensions between 720x720 and 2160x2160 pixels.
A maximum of 4 reference_images can be provided. Each image must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1.
