Video2X is a free, open-source framework for video super resolution and frame interpolation. Version 6.0.0 is a complete rewrite in C/C++ that runs on Windows and Linux. It supports two modes: filtering, which upscales footage, and frame interpolation, which raises the frame rate. Under the hood it can apply Anime4K v4 or any custom MPV-compatible GLSL shader, and it runs Real-ESRGAN, Real-CUGAN and RIFE models through ncnn and Vulkan. Processing needs no extra disk space beyond the final output, and there is no paid plan.
The software suits hobbyists restoring old anime, archivists improving low-resolution footage, video editors who want a free upscaler, and developers who like command-line tools and container deployment. A Windows GUI with an installer covers basic use in English, Chinese, Japanese, Portuguese, French and German, while Linux users can install AUR packages or a universal AppImage. Users should have a CPU with AVX2 support, meaning Intel Haswell or AMD Excavator and newer, and a Vulkan-capable GPU from NVIDIA, AMD or Intel.
Typical projects include upscaling a standard-definition cartoon series to a higher resolution, smoothing a 24 fps clip with RIFE interpolation, and batch processing files on a Linux server through the published Docker or Podman image. People without a strong graphics card can run it on Google Colab, which lends an NVIDIA T4, L4 or A100 GPU for free for up to 12 hours per session. A documentation book, a Telegram discussion group and an active repository with more than 1,000 commits support troubleshooting.
