You can go to the releases page to download the latest builds of Video2X
. The exe files will require no Python or Python module installation.
The full
package provides all packages that will possibly be needed by Video2X
, including FFmpeg
, waifu2x-caffe
, waifu2x-converter-cpp
, and waifu2x-ncnn-vulkan
. The config file (video2x.json
) is also already configured for the environment. All you need to do is just to launch video2x.exe
.
The light
package provides only the most basic functions of Video2X
. Only video2x.exe
, video2x_setup.exe
and video2x.json
are included. To setup dependencies (e.g. FFmpeg
and Waifu2X
) automatically, simply launch video2x_setup.exe
.
Component names that are bolded can be automatically downloaded and configured with the video2x_setup.py
script.

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:

You can find all detailed user-facing and developer-facing documentations in the Video2X Wiki. It covers everything from step-by-step instructions for beginners, to the code structure of this program for advanced users and developers. If this README page doesn't answer all your questions, the wiki page is where you should head to.
For those who want a detailed walk-through of how to use Video2X
, you can head to the Step-By-Step Tutorial wiki page. It includes almost every step you need to perform in order to enlarge your first video.
Go to the Waifu2X Drivers wiki page if you want to see a detailed description on the different types of waifu2x
drivers implemented by Video2X
. This wiki page contains detailed difference between different drivers, and how to download and set each of them up for Video2X
.

- Python 3
Download: https://www.python.org/downloads/windows/ - FFmpeg Windows Build
Download: https://ffmpeg.org/download.html - waifu2x-caffe (for Nvidia CUDA/CUDNN)
Download: https://github.com/lltcggie/waifu2x-caffe/releases - waifu2x-converter-cpp (required for AMD, OpenCL and OpenGL processing)
Download: https://github.com/DeadSix27/waifu2x-converter-cpp/releases
First, clone the video2x repository.
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 dependencies automatically. This script is designed and tested on Windows 10.
This script will install the newest version of ffmpeg
, any one or all waifu2x-caffe
, waifu2x-converter-cpp
, and waifu2x-ncnn-vulkan
to %LOCALAPPDATA%\\video2x
and all required python libraries.
python 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.
pip install -r requirements.txt
Note that all command line arguments/options overwrite configuration file settings.
If you can't find a video clip to begin with, or if you want to see a before-after comparison, we have prepared some sample clips for you. The quick start guide down below will also be based on the name of the sample clips.

Enlarge the video to 1920x1080 using CUDA. You may also use the -r/--ratio
option.
python video2x.py -i sample_input.mp4 -o sample_output.mp4 -m gpu --width=1920 --height=1080
Enlarge the video to 1920x1080 using CUDNN. You may also use the -r/--ratio
option.
python video2x.py -i sample_input.mp4 -o sample_output.mp4 -m cudnn --width=1920 --height=1080
Enlarge the video by 2 times using OpenCL. Note that waifu2x-converter-cpp
doesn't support width and height. You'll also have to explicitly specify that the driver to be used is waifu2x_converter
.
python video2x.py -i sample_input.mp4 -o sample_output.mp4 -m gpu -r 2 -d waifu2x_converter
python video2x.py -i sample_input.mp4 -o sample_output.mp4 -m gpu -r 2 -d waifu2x_ncnn_vulkan
Enlarge the video to 1920x1080 using the CPU. You may also use the -r/--ratio
option. This is potentially much slower than using a GPU. The configuration file for this method is similar to the previous methods.
python video2x.py -i sample_input.mp4 -o sample_output.mp4 -m cpu --width=1920 --height=1080
