The Kling1.6: FLF2V workflow is designed to generate videos by precisely controlling the first and last frames, offering a unique approach to video synthesis. This workflow leverages the Kling model, specifically version 1.6, to ensure high-quality frame generation. The process begins with the LoadImage node, which allows users to input their desired starting and ending frames. These frames are then processed through the KlingStartEndFrameNode, a specialized node that interpolates the frames to create a smooth transition throughout the video. This node is crucial as it utilizes advanced algorithms to maintain consistency and coherence in the generated video.
The workflow concludes with the SaveVideo node, which compiles the interpolated frames into a seamless video file. Additionally, the MarkdownNote node provides users with contextual information and instructions, enhancing the user experience. This workflow is particularly useful for creators looking to generate videos with specific start and end visuals, making it ideal for applications such as promotional content, storytelling, and artistic video projects.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
