Kreativ

Project Overview

Author: Adiel Kautu Redi

Kreativ is an AI-powered tool that generates short artistic videos from user-provided images and prompts. Inspired by SeaArt’s workflow, I created my own image-to-video generator using ComfyUI. Users interact via a simple web interface to upload images and provide descriptive prompts, which are then processed by a Flask backend.

To handle the computationally intensive AI workflow, the backend sends dynamic workflows to a cloud GPU running ComfyUI. The workflow, based on workflow_dynamic.json, is injected with user-specific prompts and executed in a serverless GPU environment. This ensures cost-efficient, scalable video generation without requiring a local GPU.

The system architecture separates concerns cleanly:

• Frontend: Handles image upload and prompt input, displays generated videos.
• Backend: Flask API injects prompts into ComfyUI workflows and communicates with the GPU.
• Cloud GPU: Executes ComfyUI workflows on-demand, returning generated video URLs.
