About video2x

Video2X makes tiny or stuttery clips look larger and smoother. It handles two tasks: upscaling (enlarging the picture) and frame interpolation (adding frames for smooth motion). Ready-made builds want a Vulkan GPU and a fairly new CPU. AGPL-3.0, free, and it runs on Windows and Linux.

Best for: Editors who want to sharpen and smooth old anime or low-res AI short-drama footage.

What it does

  • Upscales video with Anime4K v4, Real-ESRGAN and Real-CUGAN models
  • Adds frames with RIFE models to smooth choppy motion
  • Loads custom MPV-compatible GLSL shaders for filtering
  • Runs on Windows and Linux with Vulkan GPU acceleration
  • Ships a Qt6 desktop app in six languages
  • Offers a Docker image and a free Google Colab notebook
