Batch Upscale to 4K in ComfyUI (Only 4GB GPU!) | Python Automation Tutorial

Описание: 📝 YouTube Description

Turn your low-spec PC into a 4K image-upscaling powerhouse!
In this tutorial, I show how I upscale 200–300 images in batch to 4K resolution using ComfyUI + Python automation — even on a system with 4GB VRAM and 16GB RAM.

This workflow avoids memory errors by processing one image at a time, making it perfect for budget hardware.

🚀 What you’ll learn
ComfyUI upscale setup (simple clean workflow)
Using Remacri upscaler model from Civitai
Exporting workflow as an API JSON
Writing & running Python script to batch-process images
Avoiding VRAM/RAM crashes on low-hardware
Folder setup & path configuration
Running the automation script in Visual Studio

💡 Important Note
Visual Studio is not the only way to run this.
You can run the Python script from VS Code, Terminal, Jupyter, PyCharm, etc.
Visual Studio is just what I used in the video.
