Download Stable/Beta Builds (Windows)

  • Full: full package comes pre-configured with all dependencies like FFmpeg and waifu2x-caffe.
  • Light: ligt package comes with only Video2X binaries and a template configuration file. The user will either have to run the setup script or install and configure dependencies themselves.

Go to the Quick Start section for usages.

Download From Mirror

In case you’re unable to download the releases directly from GitHub, you can try downloading from the mirror site hosted by the author. Only releases will be updated in this directory, not nightly builds.

Download Nightly Builds (Windows)

You need to be logged into GitHub to be able to download GitHub Actions artifacts.

Nightly builds are built automatically every time a new commit is pushed to the master branch. The lates nightly build is always up-to-date with the latest version of the code, but is less stable and may contain bugs. Nightly builds are handled by GitHub’s integrated CI/CD tool, GitHub Actions.

To download the latest nightly build, go to the GitHub Actions tab, enter the last run of workflow “Video2X Nightly Build, and download the artifacts generated from the run.

Docker Image

Video2X Docker images are available on Docker Hub for easy and rapid Video2X deployment on Linux and macOS. If you already have Docker installed, then only one command is needed to start upscaling a video. For more information on how to use Video2X’s Docker image, please refer to the documentations.

Introduction

Video2X is a video/GIF/image upscaling software based on Waifu2X, Anime4K, SRMD and RealSR written in Python 3. It upscales videos, GIFs and images, restoring details from low-resolution inputs. Video2X also accepts GIF input to video output and video input to GIF output.

Currently, Video2X supports the following drivers (implementations of algorithms).

  • Waifu2X Caffe: Caffe implementation of waifu2x
  • Waifu2X Converter CPP: CPP implementation of waifu2x based on OpenCL and OpenCV
  • Waifu2X NCNN Vulkan: NCNN implementation of waifu2x based on Vulkan API
  • SRMD NCNN Vulkan: NCNN implementation of SRMD based on Vulkan API
  • RealSR NCNN Vulkan: NCNN implementation of RealSR based on Vulkan API
  • Anime4KCPP: CPP implementation of Anime4K

Quick Start

Prerequisites

Before running Video2X, you’ll need to ensure you have installed the drivers’ external dependencies such as GPU drivers.

  • waifu2x-caffe
    • GPU mode: Nvidia graphics card driver
    • cuDNN mode: Nvidia CUDA and cuDNN
  • Other Drivers
    • GPU driver if you want to use GPU for processing

Running Video2X (GUI)

The easiest way to run Video2X is to use the full build. Extract the full release zip file and you’ll get these files.

Video2X Release Files
Video2X release files

Simply double click on video2x_gui.exe to launch the GUI.

Video2X GUI Main Tab

Then, drag the videos you wish to upscale into the window and select the appropriate output path.

drag-drop
Drag and drop file into Video2X GUI

Tweak the settings if you want to, then hit the start button at the bottom and the upscale will start. Now you’ll just have to wait for it to complete.

Running Video2X (CLI)

Basic Upscale Example

This example command below uses waifu2x-caffe to enlarge the video sample-input.mp4 two double its original size.

python video2x.py -i sample-input.mp4 -o sample-output.mp4 -r 2 -d waifu2x_caffe

Advanced Upscale Example

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.yamlCommand line arguments will overwrite default values in the config file.

This example below adds enables TTA for waifu2x-caffe.

python video2x.py -i sample-input.mp4 -o sample-output.mp4 -r 2 -d waifu2x_caffe -- --tta 1

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.

python video2x.py -d waifu2x_caffe -- --help

Running Video2X (Docker)

Video2X can be deployed via Docker. The following command upscales the video sample_input.mp4 two times with Waifu2X NCNN Vulkan and outputs the upscaled video to sample_output.mp4. For more details on Video2X Docker image usages, please refer to the documentations.

docker run --rm -it --gpus all -v /dev/dri:/dev/dri -v $PWD:/host k4yt3x/video2x:4.6.0 -d waifu2x_ncnn_vulkan -r 2 -i sample_input.mp4 -o sample_output.mp4

This project relies on the following software and projects.

Special Thanks

Appreciations given to the following personnel who have contributed significantly to the project (specifically the technical perspective).

  • Dandere2x: A lossy video upscaler also built around waifu2x, but with video compression techniques to shorten the time needed to process a video.
  • Waifu2x-Extension-GUI: A similar project that focuses more and only on building a better graphical user interface. It is built using C++ and Qt5, and currently only supports the Windows platform.
