KlingTextToVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

The Kling Text to Video node generates videos from text descriptions using the Kling video generation API. It sends the prompt and settings (aspect ratio, generation mode, and CFG scale) to the API, waits for the generation task to complete, and then returns the resulting video along with its ID and duration.

`prompt`	Positive text prompt describing the desired video content	STRING	Yes	Maximum 2500 characters
`negative_prompt`	Negative text prompt describing what to avoid in the video	STRING	No	Maximum 2500 characters
`cfg_scale`	Configuration scale value that controls how closely the video follows the prompt (default: 1.0)	FLOAT	No	0.0 to 1.0
`aspect_ratio`	Video aspect ratio setting (default: “16:9”)	COMBO	No	”16:9" "9:16" "1:1”
`mode`	The configuration to use for the video generation following the format: mode / duration / model_name (default: “pro mode / 5s duration / kling-v2-5-turbo”)	COMBO	No	”pro mode / 5s duration / kling-v2-5-turbo" "pro mode / 10s duration / kling-v2-5-turbo”
