Introduction

Vapourkit is a free, open source application for video upscaling and enhancement using VapourSynth and AI models. It provides a user-friendly interface for video processing with support for both NVIDIA TensorRT and DirectML (AMD/Intel/NVIDIA) backends.

What it does

  • AI Video Upscaling — process videos with high-quality AI upscaling models
  • Dual Backend Support — TensorRT (NVIDIA) or DirectML (AMD/Intel/NVIDIA)
  • Real-time Preview — see results while processing
  • Video Comparison — built-in side-by-side viewer
  • Batch Processing — upscale multiple videos sequentially
  • Pre-made Filters — dozens of ready-to-use filters
  • Custom VapourSynth Filters — write and chain custom video processing filters
  • Templates & Workflows — save and share filter configs (.vkfilter) and complete workflows (.vkworkflow)
  • Custom Models — import your own ONNX models

Who it’s for

  • Restoration enthusiasts working with archival video
  • Anime and film communities upscaling SD or LQ sources
  • Anyone who wants AI-driven video enhancement without writing VapourSynth scripts by hand
