This workflow builds fast, client-ready casting previs for advertising in two passes: a photo-real still and a short motion test. In STEP 1 – PREVIS STILL FRAME, your talent headshot (LoadImage) is combined with a scene description to synthesize a single frame of the talent in context (e.g., tennis court, soda product). Prompt text from MarkdownNote and PrimitiveNode is merged with shot directions using StringConcatenate, and GeminiImage2Node performs image-to-image guided synthesis using the headshot and any optional product/environment references. The resulting frame is saved with SaveImage for quick side-by-side casting reviews.

STEP 2 – PREVIS VIDEO upgrades that still into a short motion clip. ImageBatchMulti assembles one or more selected stills into a batch, and KlingOmniProImageToVideoNode generates a quick image-to-video preview—ideal for validating basic motion like a gentle dolly-in, a sip, and a look-to-can. SaveVideo writes the final clip to disk. Because the video is derived from your approved still, character identity and wardrobe cues tend to remain consistent across frames, making it well-suited for talent casting, pitch decks, and early client sign-off.

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
