This ComfyUI workflow turns a single still image into a high-fidelity video clip using the Wan 3.0 Image-to-Video API. It’s built around four nodes: LoadImage to bring your source frame into the graph, Wan3ImageToVideoApi to generate the animated sequence on a remote service, SaveVideo to encode the frames to a standard video file, and MarkdownNote for inline instructions. The pipeline is simple and reliable: your input image is loaded, sent to Wan 3.0 for temporal synthesis, and the returned frames are packaged into a playable video.

Technically, Wan 3.0 performs motion synthesis conditioned on the content of the single image, producing realistic camera/lens movement and subject dynamics in one pass. While the Wan 3.0 family supports multimodal inputs, this specific workflow is image-only and focuses on up to 30 seconds of output. You control the key generation settings in the Wan3ImageToVideoApi node (e.g., clip duration and any parameters exposed by your API endpoint), and finalize playback characteristics like FPS and file path in SaveVideo. This makes it well-suited for cinematic b-roll, product hero shots, and documentary-style scene recreation directly from a still.

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 Python or TypeScript with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.

# Install (beta)
pip install comfy-sdk        # Python
npm i @comfyorg/sdk          # TypeScript

# Run this workflow (Python)
from comfy_sdk import Comfy

client = Comfy(api_key="comfyui-...")
wf = client.workflows.from_file("workflow_api.json")
job = client.run(wf)
for output in job.get_outputs("<output-node-id>"):
    output.to_file(output.name)

The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API). API access requires a Comfy Cloud plan with an API key. SDK docs · Get an API key
