This ComfyUI workflow turns a single still image into a polished 1080p video clip using Seedance 2.5 via the ByteDance2ReferenceNodeV2. The graph is intentionally simple and reliable: LoadImage brings your source frame into the pipeline, ByteDance2ReferenceNodeV2 synthesizes motion-conditioned frames from that reference, and SaveVideo encodes the output sequence to a playable MP4 at your chosen frame rate and aspect ratio. You control duration (up to ~30 seconds), FPS, motion strength, and seeding for reproducible results.
Technically, the ByteDance2ReferenceNodeV2 uses the input image as a visual prior, generating a temporally coherent frame sequence that preserves identity and structure while introducing camera-like moves (e.g., gentle pans, zooms, and parallax) and scene dynamics. Because resolution and aspect ratio are configurable, you can produce 1920x1080 landscape, 1080x1920 vertical, or square clips while maintaining 1080 on the long edge. SaveVideo then assembles frames at the specified FPS. Note: this minimal graph outputs video only; to add music, dialogue, or foley, mux audio afterward or extend the workflow with audio nodes/external tools.
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.
