## 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.

For short: **Video2X enlarges your video without losing details**

Watch for the sharper edges in this screenshot around the shadows:

## 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

First, clone the video2x repository.

```bash
$ git clone https://github.com/K4YT3X/video2x.git
$ cd video2x/bin
```

Then you may 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
```

Alternatively, you can also install the dependencies manually. Please refer to the prerequisites section to see what's needed.

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
```


## Full Usage

```
usage: video2x.py [-h] -i INPUT -o OUTPUT -m {cpu,gpu,cudnn}
                  [-y {upconv_7_anime_style_art_rgb,upconv_7_photo,anime_style_art_rgb,photo,anime_style_art_y}]
                  [-t THREADS] [-c CONFIG] [--width WIDTH] [--height HEIGHT]
                  [-f FACTOR]

optional arguments:
  -h, --help            show this help message and exit

Basic Options:
  -i INPUT, --input INPUT
                        Specify source video file/directory
  -o OUTPUT, --output OUTPUT
                        Specify output video file/directory
