KlingFirstLastFrameNode - ComfyUI Built-in Node Documentation - ComfyUI

This node uses the Kling 3.0 model to generate a video. It creates the video based on a text prompt, a specified duration, and two provided images: a starting frame and an ending frame. The node can also generate accompanying audio for the video.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
`model`	Model and generation settings. Selecting this option reveals a nested `resolution` parameter.	DYNAMIC_COMBO	No	`"kling-v3"`
`prompt`	The text description that guides the video generation. Must be between 1 and 2500 characters long.	STRING	Yes	N/A
`duration`	The length of the video in seconds (default: 5).	INT	No	3 to 15
`first_frame`	The starting image for the video. Must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1.	IMAGE	Yes	N/A
`end_frame`	The ending image for the video. Must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1.	IMAGE	Yes	N/A
`generate_audio`	Controls whether to generate audio for the video (default: True).	BOOLEAN	No	N/A
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 0).	INT	No	0 to 2147483647

Kling V3 Inputs

Parameter	Description	Data Type	Required	Range
`resolution`	The resolution for the generated video (default: `"1080p"`).	COMBO	No	`"4k"` `"1080p"` `"720p"`

Note: The first_frame and end_frame images must be at least 300x300 pixels and have an aspect ratio between 1:2.5 and 2.5:1 for the node to function correctly. The prompt must be between 1 and 2500 characters. The resolution option maps to a Kling generation mode: "4k", "1080p" (pro), and "720p" (standard).
