### Official [Telegram Discussion Group](https://t.me/video2x) Join our Telegram discussion group to ask any questions you have about Video2X, chat directly with the developers, or discuss about upscaling technologies and the future of Video2X in general. ## [🪟 Download Windows Releases](https://github.com/k4yt3x/video2x/releases/tag/4.8.1) The latest Windows update is built based on version 4.8.1. GUI is not available for 5.0.0 yet, but is already under development. Go to the [GUI](https://github.com/k4yt3x/video2x/wiki/GUI) page to see the basic usages of the GUI. Try the [mirror](https://files.k4yt3x.com/Projects/Video2X/lates) if you can't download releases directly from GitHub. ## [📔 Google Colab](https://colab.research.google.com/drive/1gWEwcA9y57EsxwOjmLNmNMXPsafw0kGo) You can use Video2X on [Google Colab](https://colab.research.google.com/) **for free** if you don't have a powerful GPU of your own. You can borrow a powerful GPU (Tesla K80, T4, P4, or P100) 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+](https://colab.research.google.com/signup/pricing) if you'd like to use better GPUs and get longer runtimes. Usage instructions are embedded in the [Colab Notebook](https://github.com/k4yt3x/video2x/actions/workflows/ci.yml). ## [🌙 Download Nightly Releases](https://github.com/k4yt3x/video2x/actions/workflows/ci.yml) Nightly releases are automatically created by the GitHub Actions CI/CD pipelines. They usually contain more experimental features and bug fixes. However, they are much less stable to the stable releases. **You must log in to GitHub to download CI build artifacts.** ## [📦 Container Image](https://github.com/k4yt3x/video2x/pkgs/container/video2x) 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 For more information on how to use Video2X's Docker image, please refer to the [documentations (outdated)](https://github.com/K4YT3X/video2x/wiki/Docker). ## [📖 Documentations](https://github.com/k4yt3x/video2x/wiki) Video2X's documentations are hosted on this repository's [Wiki page](https://github.com/k4yt3x/video2x/wiki). It includes comprehensive explanations for how to use the [GUI](https://github.com/k4yt3x/video2x/wiki/GUI), the [CLI](https://github.com/k4yt3x/video2x/wiki/CLI), the [container image](https://github.com/K4YT3X/video2x/wiki/Container), the library, and more. The Wiki is open to edits by the community, so you, yes you, can also correct errors or add new contents to the documentations. ## Introduction Video2X is a video/GIF/image upscaling and frame interpolation software written in Python. It can use these following state-of-the-art algorithms to increase the resolution and frame rate of your video/GIF/image. More information about the algorithms that it supports can be found in [the documentations](https://github.com/k4yt3x/video2x/wiki/Algorithms). ### Video Upscaling \ _Upscale demo: Spirited Away's movie trailer_ - **Spirited Away**: [YouTube](https://youtu.be/mGEfasQl2Zo) | [Bilibili](https://www.bilibili.com/video/BV1V5411471i/) - 360P to 4K - The [original video](https://www.youtube.com/watch?v=ByXuk9QqQkk)'s copyright belongs to 株式会社スタジオジブリ - **Bad Apple!!**: [YouTube](https://youtu.be/A81rW_FI3cw) | [Bilibili](https://www.bilibili.com/video/BV16K411K7ue) - 384P to 4K 120FPS - The [original video](https://www.nicovideo.jp/watch/sm8628149)'s copyright belongs to あにら - **The Pet Girl of Sakurasou**: [YouTube](https://youtu.be/M0vDI1HH2_Y) | [Bilibili](https://www.bilibili.com/video/BV14k4y167KP/) - 240P to 1080P 60FPS - The original video's copyright belongs to ASCII Media Works ### GIF Upscaling  \ _Catfru scaled up to 4x its original size using waifu2x [(original image)](https://gfycat.com/craftyeasygoingankole-capoo-bug-cat)_ ### Image Upscaling \ _Image 8x upscaling demo ([original image](https://72915.tumblr.com/post/173793265673) by [nananicu](https://twitter.com/nananicu))_ ### Standard Test Clip The following clip can be used to test if your setup works properly.

It is built using C++ and Qt5, and currently only supports the Windows platform.
