  • offers significantly better output quality with Anime4K v4, RealESRGAN, RealCUGAN, and RIFE;
  • supports two modes: filtering (upscaling) and frame interpolation;
  • supports Anime4K v4 and all custom MPV-compatible GLSL shaders;
  • supports RealESRGAN, RealCUGAN, and RIFE (all models) via ncnn and Vulkan;
  • requires zero additional disk space during processing, just space for the final output.

🪟 Install on Windows

Download the Latest Windows Installer Executable (6.3.1)

You can download the latest Windows release on the releases page. For basic GUI usage, refer to the documentation. If you’re unable to download directly from GitHub, try the mirror site. The GUI currently supports the following languages:

  • English (United States)
  • 简体中文（中国）
  • 日本語（日本）
  • Português (Portugal)
  • Français (France)

🐧 Install on Linux

Video2X packages are available for the Linux distros listed below. If you’d like to build it from source code, refer to the PKGBUILD file for a general overview of the required dependencies and commands. If a package is not available for your distro and you prefer not to compile the program from source code, consider using the container image outlined in the next section.

📦 Container Image

Video2X container images are available on the GitHub Container Registry for easy deployment on Linux and macOS. If you already have Docker/Podman installed, 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 documentation.

📔 Google Colab

You can use Video2X on Google Colab for free if you don’t have a powerful GPU of your own. You can borrow a powerful GPU (NVIDIA T4, L4, or A100) on Google’s server for free for a maximum of 12 hours per session. Please use the free resource fairly and do not create sessions back-to-back and run upscaling 24/7. This might result in you getting banned. You can get Colab Pro/Pro+ if you’d like to use better GPUs and get longer runtimes. Usage instructions are embedded in the Colab Notebook.
