• Installation
  • Windows
  • Arch Linux

Usage

1. Preparing video file (MKVToolNix)
   • Make sure video file does NOT have an image attachment
   • Video file should have ONE ass subtitle file
   • Name video file similar to the following: Your Title - 01.mkv
2. Place .mkv file inside 0-Source folder
3. Execute python Start.py

Configuration

The Start.py file has two options INSIDE, edit in text editor:

• INTERPOLATE_4K: True or False (wether or not 4k48fps should be outputted)
• MAX_INPUT_WIDTH: '720' (downscales the video to this width, as 1080p upscaling would be insane)

Requirements

• OS: Windows or Linux
• Python: >=3.12 (Windows) or Python 3.13 (Linux)
• RAM: Min: 16GB - Recommended: 32GB

Requirements for 1080p, 1080p@48, 4k

• GPU: NVIDIA GPU with 8GB+ of VRAM

Requirements for 4k48fps

• GPU: NVIDIA GPU with 24GB of VRAM
• RAM (Linux): 48GB (there is a memory leak in VapourSynth)

Installation

Windows

1. Download and install Python 3.12 - Check option to add to path
2. Download and install Imagemagick - Check option to install legacy tools (Required for creating player previews thumbs.vtt and sprite.jpg)
3. Download and install MKVToolNix - Add to system path environment manually
4. Download ffmpeg - Either place it inside the MKVToolNix install directory or create a new directory somewhere and add it to system path environment
5. Download and install VapourSynth R72 - Check options to install vsrepo, avisynth support not required
6. Install vsrepo packages, in Terminal (cmd, NOT Powershell!):

   :: FFmpeg Source Plugin
   vsrepo.py install ffms2
   
   :: (optional) Miscfilters Plugin, used for scenedetection in vsrife
   :: Unsure if it even works
   vsrepo.py install misc
   

7. Install pip packages

   pip install packaging setuptools wheel
   pip install pymediainfo python-dateutil
   pip install torch torchvision --index-url https://download.pytorch.org/whl/cu126
   pip install vsrealesrgan vsrife
   

8. Install models used by vsrealesrgan and vsrife

   python -m vsrealesrgan
   python -m vsrife
   

Arch Linux

Sadly there is some sort of memory leak in vsrife or vapoursynth under Linux.

If you have 32GB of RAM it should suffice for everything EXCEPT 4k48p, there you probably need 48GB or 64GB of RAM.

# System Packages
