## Description

Video2X is an automation software based on waifu2x image enlarging engine. It extracts frames from a video, enlarge it by a number of times without losing any details or quality, keeping lines smooth and edges sharp.

## Installation

### Prerequisites

- **Python 3**  
Download: https://www.python.org/downloads/windows/
- **FFMPEG Windows Build**  
Download: https://ffmpeg.org/download.html  
- **waifu2x-caffe for Windows**  
Download: https://github.com/lltcggie/waifu2x-caffe/releases

### Install Dependencies

You can run the `video2x_setup.py` script to install and configure the depencies automatically. This script is designed and tested on Windows 10.

This script will install `ffmpeg`, `waifu2x-caffe` to `%LOCALAPPDATA%\\video2x` and all python libraries.

```bash
$ python bin/video2x_setup.py
```

After downloading the dependencies, clone the video2x package.

```bash
$ git clone https://github.com/K4YT3X/video2x.git
$ cd video2x/bin
```
Then you'll need to install python dependencies before start using video2x. Install simply by executing the following command.

```bash
$ pip install -r requirements.txt
```

## Quick Start

To enlarge a video on a computer with NVIDIA GPU

```bash
$ python video2x.py -i video.mp4 -o video.mp4 -m gpu --width=1920 --height=1080
```

To enlarge a video on a computer with CPU

```bash
$ python video2x.py -i video.mp4 -o video.mp4 -m cpu --width=1920 --height=1080
```
