Kling Start-End Frame to Video

api node/video/Kling

KlingStartEndFrameNode

Generate a video sequence that transitions between your provided start and end images. The node creates all frames in between, producing a smooth transformation from the first frame to the last.

Example

JSON Example

{
  "class_type": "KlingStartEndFrameNode",
  "inputs": {
    "start_frame": [
      "node_id",
      0
    ],
    "end_frame": [
      "node_id",
      0
    ],
    "prompt": "a beautiful landscape, high quality, detailed",
    "negative_prompt": "blurry, low quality",
    "cfg_scale": 0.5,
    "aspect_ratio": null,
    "mode": "pro mode / 5s duration / kling-v2-5-turbo"
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
start_frame?	IMAGE	required	-	-
end_frame?	IMAGE	required	-	-
prompt?	STRING	required	-	-
negative_prompt?	STRING	required	-	-
cfg_scale	FLOAT	required	min: 0, max: 1	0.5
aspect_ratio	COMBO	required	-	-
mode?	COMBO	required	-	"pro mode / 5s duration / kling-v2-5-turbo"

Outputs

Index	Name	Type	Is List	Connection Reference
0	VIDEO	VIDEO	No	["{node_id}", 0]
1	video_id	STRING	No	["{node_id}", 1]
2	duration	STRING	No	["{node_id}", 2]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this KlingStartEndFrameNode node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• VIDEO (VIDEO): ["5", 0]
• video_id (STRING): ["5", 1]
• duration (STRING): ["5", 2]
