3. Select the plugin file. It will be installed permanently. (To uninstall, simply delete the file from the plugins folder via Config > Open Plugins Folder).

Available Plugin

1. Video Upscaler

File: VideoUpscaler.kit Status: Released

Upscale video files significantly using the power of Real-ESRGAN and FFmpeg. This plugin automates the complex process of frame-by-frame AI enhancement.

Workflow:

1. Extract: Breaks down the video into individual frames.
2. Upscale: Processes frames in batch using AI models (Scale 2x - 4x).
3. Merge: Recombines frames into a video file while preserving the original audio.

⚠️ Note: This process is resource-intensive (GPU/CPU) and may take a long time depending on the video length and upscaling factor.

2. ONNX Loader

File: ONNXLoader.kit Status: Released

A bridge for advanced users. Allows you to load external .onnx Upscaler models into LABOKit's interface, making it easy to test and use custom models found online.

3. QR-Code Generator

File: QRCodeGenerator.kit Status: Released

A batch-able QR-Code generator.

Prerequisites

• Python 3.10+
• Windows (Recommended)

Setup

1. Clone the repository:

   git clone [https://github.com/wagakano/LABOKit.git](https://github.com/wagakano/LABOKit.git)
   cd LABOKit
   

2. Install dependencies:

   pip install -r requirements.txt
   

   (Note: PyTorch and RealESRGAN modules are required for full feature support)

3. Model Setup

   • BG Remover (rembg)
     • Manual (Offline): for manual setup, download u2net.onnx and isnet-anime.onnx, create a folder named models in the project root, and place the file there (LABOKit/models/).
   • Upscaler (realesrgan) - ensure the realesrgan_ncnn folder (containing the executable) and the models folder (containing .pth files) are correctly placed in the project directory.
     • Download realesrgan-ncnn-vulkan.exe and the models (e.g., realesrgan-x4plus.bin, etc.).
     • Place them in the realesrgan_ncnn/ folder inside the project directory.\
     • Add realesr-general-x4v3.pth into realesrgan_ncnn/models/
     • (Note: Ensure the executable path matches the setup in main.py)

4. Run the application:

   python main.py
