## Download Builds (Windows)
2019-03-31 07:58:09 +00:00
You can go to the [releases page ](https://github.com/k4yt3x/video2x/releases ) to download the latest builds of `Video2X` . The exe files will require no Python or Python module installation.
2020-05-05 05:51:24 +00:00
The ** `full` ** package provides all packages that will possibly be needed by `Video2X` , including `FFmpeg` , `waifu2x-caffe` , `waifu2x-converter-cpp` , `waifu2x-ncnn-vulkan` , `srmd-ncnn-vulkan` and `Anime4KCPP` . The config file (`video2x.yaml`) is also already configured for the environment. All you need to do is just to launch `video2x.exe` .
2019-02-08 19:18:44 +00:00
2020-05-05 05:51:24 +00:00
The ** `light` ** package provides only the most basic functions of `Video2X` . Only `video2x.exe` , `video2x_setup.exe` and `video2x.yaml` are included. To setup dependencies (e.g. `FFmpeg` and `Waifu2X` ) automatically, simply launch `video2x_setup.exe` .

### Installing Dependencies
2018-11-29 20:12:22 +00:00
2019-02-08 19:18:44 +00:00
First, clone the video2x repository.
2019-03-26 21:58:39 +00:00
```shell
2019-04-29 04:11:30 +00:00
git clone https://github.com/k4yt3x/video2x.git
2020-05-05 05:51:24 +00:00
cd video2x/src
2019-02-08 19:18:44 +00:00
```
2019-03-26 21:58:39 +00:00
Then you may run the `video2x_setup.py` script to install and configure the dependencies automatically. This script is designed and tested on Windows 10.
2018-11-29 20:12:22 +00:00
2020-05-05 05:51:24 +00:00
This script will install the newest version of `ffmpeg` , and all upscaling drivers to `%LOCALAPPDATA%\\video2x` and all required python libraries.
2019-03-13 16:30:54 +00:00
2019-03-26 21:58:39 +00:00
```shell
python video2x_setup.py
2018-11-29 20:12:22 +00:00
```
2018-02-25 04:14:52 +00:00
2019-02-08 19:18:44 +00:00
Alternatively, you can also install the dependencies manually. Please refer to the prerequisites section to see what's needed.
2018-08-02 01:52:10 +00:00
Then you'll need to install python dependencies before start using video2x. Install simply by executing the following command.
2019-03-26 21:58:39 +00:00
```shell
pip install -r requirements.txt
2018-08-02 01:52:10 +00:00
```

### Basic Upscale Example
2019-02-08 21:49:36 +00:00
2020-05-05 05:51:24 +00:00
This example command below uses `waifu2x-caffe` to enlarge the video `sample-input.mp4` two double its original size.
2019-02-08 21:49:36 +00:00
2019-03-26 21:58:39 +00:00
```shell
2020-05-05 05:51:24 +00:00
python video2x.py -i sample-input.mp4 -o sample-output.mp4 -r 2 -d waifu2x_caffe
2019-02-08 21:49:36 +00:00
```
2020-05-05 05:51:24 +00:00
### Advanced Upscale Example
2019-02-08 21:49:36 +00:00
2020-05-05 05:51:24 +00:00
If you would like to tweak engine-specific settings, either specify the corresponding argument after `--` , or edit the corresponding field in the configuration file `video2x.yaml` . **Command line arguments will overwrite default values in the config file.**
2018-08-02 01:52:10 +00:00
2020-05-05 05:51:24 +00:00
This example below adds enables TTA for `waifu2x-caffe` .
2019-02-08 21:49:36 +00:00
2019-03-26 21:58:39 +00:00
```shell
2020-05-05 05:51:24 +00:00
python video2x.py -i sample-input.mp4 -o sample-output.mp4 -r 2 -d waifu2x_caffe -- --tta 1
2019-03-09 17:51:34 +00:00
```
2020-05-05 05:51:24 +00:00
To see a help page for driver-specific settings, use `-d` to select the driver and append `-- --help` as demonstrated below. This will print all driver-specific settings and descriptions.
2019-06-26 03:48:33 +00:00
```shell
2020-05-05 05:51:24 +00:00
python video2x.py -d waifu2x_caffe -- --help
2018-05-19 05:06:47 +00:00
```
