Installation

Supported platforms

Section titled “Supported platforms”

Vapourkit supports Windows 10/11 (x64) and x86_64, glibc-based Linux distributions that can run the AppImage.

The backend choices differ by platform:

PlatformBackends
WindowsTensorRT (NVIDIA), DirectML (AMD/Intel/NVIDIA), NCNN Vulkan
LinuxNCNN Vulkan; TensorRT on NVIDIA with a compatible CUDA/TensorRT stack

DirectML is available on Windows only.

Download

Section titled “Download”

Windows download

Linux AppImages are available from the nightly releases page. The AppImage provides the complete Vapourkit desktop application; the stable Linux build will move to Ko-fi when it is released.

Windows

Section titled “Windows”
  1. Download Vapourkit and extract the archive or run the installer.
  2. Launch Vapourkit.
  3. On first launch, click Start Setup when prompted.

Windows setup installs the managed runtime, bundled models, FFmpeg, Video Compare, and the VapourSynth plugins and filters required by the detected GPU vendor. NVIDIA systems receive TensorRT, DirectML, and NCNN Vulkan; other Windows GPU vendors receive DirectML and NCNN Vulkan.

Linux

Section titled “Linux”

Before launching Vapourkit, install these host prerequisites with your distribution’s package manager:

  • Python 3.12 or 3.13, including its venv/ensurepip package.
  • ffmpeg and ffprobe on PATH.
  • The Vulkan loader and a working GPU driver/ICD.

Then:

  1. Make the downloaded AppImage executable: chmod +x Vapourkit-*.AppImage.
  2. Run it with ./Vapourkit-*.AppImage.
  3. Click Start Setup when prompted.

Linux setup creates a private Python virtual environment and installs VapourSynth, plugins, and models under ~/.config/vapourkit-gui/data/. It does not install Python packages globally or require sudo.

Linux uses NCNN Vulkan by default on every supported GPU vendor. NVIDIA systems can also use TensorRT when a compatible CUDA/TensorRT stack is installed. DirectML is not available on Linux. Side-by-side Video Compare is optional on Linux; install the video-compare command separately with your distribution’s package manager or Linuxbrew if you want to use it.

If FUSE is unavailable, run the AppImage with APPIMAGE_EXTRACT_AND_RUN=1 ./Vapourkit-*.AppImage.

For Linux-specific diagnostics, see Linux Setup & Troubleshooting.

System requirements

Section titled “System requirements”
  • RAM: 8 GB or more recommended.
  • Storage: 5 GB minimum; 10 GB recommended for the application and dependencies.
  • GPU: 6 GB VRAM or more recommended.
  • Linux host: Python 3.12 or 3.13 with venv/ensurepip, ffmpeg, ffprobe, and a working Vulkan runtime.
  • Windows TensorRT: NVIDIA 16-series or newer with a current compatible driver.
  • Windows DirectML: AMD, Intel, or NVIDIA GPU with DirectX 12 support.
  • Linux NCNN Vulkan: a working Vulkan loader and GPU driver.
  • Linux TensorRT: NVIDIA GPU with a compatible CUDA/TensorRT installation.

Linux filter availability

Section titled “Linux filter availability”

Linux setup installs a curated catalog of verified filters rather than every filter shipped by the Windows build. The Linux catalog covers VapourSynth core filters, compatible vsjetpack filters, supported PyPI-backed filters, and the Deep Deinterlace filter with its CPU fallback.

Filters that depend on Windows-native binaries, CUDA-only plugins, Hybrid scripts, or other unverified native dependencies are hidden on Linux. The Filter Reference lists the complete catalog, while Platform Support explains the platform split; the app’s filter picker is the authoritative list for the current platform.
