The 'Vidu Q1: Start End to Video' workflow is designed to facilitate the creation of smooth video transitions between specified start and end frames. At its core, this workflow employs the Vidu Q1 model to ensure natural motion interpolation and consistent visual quality throughout the video. The workflow integrates several key nodes, including the ViduStartEndToVideoNode, which is responsible for generating the interpolated frames that create the seamless transition effect. Additionally, the LoadImage node is used to import the initial and final frames, while the SaveVideo node compiles the interpolated frames into a cohesive video file. This workflow is particularly useful for video creators and editors who need to generate fluid transitions without manual frame-by-frame adjustments, ensuring a professional finish with minimal effort.
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 "Vidu Q1: Start End to Video" (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("api_vidu_start_end_to_video_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("28", "image", asset); // LoadImage
const job = await client.run(wf);
await job.getOutputs("21")[0].toFile("output.png"); // SaveVideoThe 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.
