KlingImage2VideoNode - ComfyUI Built-in Node Documentation

The Kling Image to Video Node generates a video from a starting reference image using text prompts. It takes an image as the first frame and creates a video sequence based on positive and negative text descriptions, with configurable options for model, duration, aspect ratio, and generation mode.

Inputs

Parameter	Description	Data Type	Required	Range
`start_frame`	The reference image used to generate the video. The image must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1.	IMAGE	Yes	-
`prompt`	Positive text prompt. Maximum 500 characters.	STRING	Yes	-
`negative_prompt`	Negative text prompt. Maximum 500 characters.	STRING	Yes	-
`model_name`	The model used for video generation (default: `"kling-v2-master"`).	COMBO	Yes	`"kling-v2-master"` `"kling-v2-1-master"` `"kling-v2-5-turbo"` `"kling-v2-1"` `"kling-v1-6"` `"kling-v1-5"` `"kling-v1-4"` `"kling-v1-0"`
`cfg_scale`	Controls how closely the video follows the prompt. Higher values mean stronger adherence (default: 0.8).	FLOAT	Yes	0.0 to 1.0
`mode`	The generation mode. `"std"` is standard quality, `"pro"` is higher quality (default: `"std"`). Note: When using the `kling-v2-5-turbo` model, `"std"` mode is not supported and will be automatically switched to `"pro"`.	COMBO	Yes	`"std"` `"pro"`
`aspect_ratio`	The aspect ratio of the generated video (default: `"16:9"`).	COMBO	Yes	`"16:9"` `"9:16"` `"1:1"`
`duration`	The duration of the generated video in seconds (default: `"5"`).	COMBO	Yes	`"5"` `"10"`

Outputs

Output Name	Description	Data Type
`output`	The generated video output.	VIDEO
`video_id`	Unique identifier for the generated video.	STRING
`duration`	Duration information for the generated video.	STRING
