What does GeminiImage2Node do in this workflow?

GeminiImage2Node performs the main image-to-image transformation (such as enhancement or style harmonization) on each input image. Its exact effect depends on how you configure its parameters in the workflow. Open the node to adjust strength, style, or other controls to fit your product look.

How does the ByteDance2FirstLastFrameNode create the video?

It takes two processed stills (usually the first and last frames from your batch) and interpolates new frames between them, producing a short, smooth transition. Adjust the node’s frame-count or duration settings to control motion length and smoothness, then SaveVideo writes the final clip.

What is the purpose of the custom node f4fca0c6-bff8-4410-84df-a9d8961ce181?

It’s a utility step used for pre/post-processing, such as resizing, padding to a target aspect ratio, or other formatting tasks. Open the node to review its parameters and ensure they match your target output (e.g., square thumbnails or specific resolutions).

Can I run this on a batch of mixed sizes and orientations?

Yes, but for best results standardize inputs. Use the custom node to normalize resolution/aspect ratio so GeminiImage2Node applies changes consistently and the ByteDance interpolation produces smooth motion without warping.

Ohneis - Product Workflow - ComfyUI Workflow

Ohneis - Product Workflow is a streamlined ComfyUI pipeline for batch-processing product photos and turning them into clean, consistent assets with optional motion clips. It starts with LoadImage and BatchImagesNode to pull in one or more source photos and apply identical processing across the set. The images are passed through GeminiImage2Node, which performs the core image-to-image transformation configured in your workflow (for example, enhancement, style harmonization, or light retouching). A custom utility node (ID: f4fca0c6-bff8-4410-84df-a9d8961ce181) is included for pre/post-processing—such as resizing, padding, or color/format normalization—before final outputs are written by SaveImage.

For motion, ByteDance2FirstLastFrameNode generates a short product video by interpolating between two processed stills (typically the first and last in the batch), producing smooth in-between frames for a subtle pan, spin, or reveal effect. SaveVideo then writes the final clip. The combination of batch consistency (BatchImagesNode), controlled image-to-image processing (GeminiImage2Node), and first/last-frame interpolation (ByteDance2FirstLastFrameNode) makes this workflow well-suited to e-commerce catalogs and quick social-ready product reels with minimal setup.

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.

Fetching workflow JSON…

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.
