👋 Hello, I'm Setsugen.

I'm a Full-Stack Web and Desktop developer from Italy.

My open source projects are mainly Python oriented, though I also like using TypeScript, C++ and recently, Rust.

In my spare time (a bit less since starting university 😅), I like working on the many side projects I started, fansub, or contribute to open-source projects I like.

Since Summer 2022 I've started rewriting many functions and packages in the VapourSynth community, and now most of the packages are on stable API; you hopefully know me because you use one of these tools 🚀

You can find most of my VapourSynth stuff in the Irrational Encoding Wizardry repository.

• vs-tools
  • Backbone of all the following packages. It's got a User and Dev side of APIs you can use to easily write scripts and functions or packages.
• vs-pyplugin
  • Fun project at the start that ended up as a complex package that makes it possible to easily write full fledged VS Plugins from Python with Python/Cython/Numpy/Cupy/Cuda backends and JIT compiling when applicable.
• vs-kernels
  • First layer of package abstraction which implements the whole "Scaler ecosystem".
• vs-exprtools
  • WIP package that aims to make writing RPN expressions as easy as possible and optimizing/compiling them (WIP part).
• vs-rgtools
  • It's a package that implements functions and wraps plugins for denoising or prefiltering with the same idea of blurring and using convolutions as the removegrain plugin.
• vs-masktools
  • Fork of the stale vsmask. This implements features from other unmaintained packages and new functions for creating edge masks.
• vs-aa
  • Package based on antialiaser plugins, with the functionality of singlerating/doublerating or generaling scaling which is made possible by the abstraction in Scalers from vs-kernels.
• vs-scale
  • Basically a union of vs-kernels and vs-aa to create functions to scale/descale, among special Scalers.
• vs-denoise
  • Abstraction and wrappers over all the useful denoising plugins. The main things I developed are MVTools, and a "Regression API" for mathematical operations.
• vs-dehalo
  • Complex and highly configurable dehaloing and deringing functions.
• vs-deband
  • WIP package that aims to make common ground over all debanders and grainers we have available, with additional functions for pre/post processing.
• vs-deinterlace
  • WIP Package for deinterlacing functions. Will eventually hold a complex, highly configurable rewrite of QTGMC.
• vs-preview
  • Previewer for VapourSynth with a lot of functionality.
• vs-parsedvd
  • WIP package that aims to ease the use of indexers. Was started as a fun project to open DVDs automagically, but will be repurposed and renamed as vs-indexers sometime.
• vs-dfft
  • Package with a single function implementing a dfft spectrum viewer. Will be eventually made into a vs-preview plugin.

A package I'm happy of doing is ctyped-ffi which makes it possible to define FFI libraries just with typing. Implements cpython fixes, possibility of creating c functions from python and will eventually include a ctypes python package reimplementation with full typing.

The last package made possible the creation of vapoursynth-capi, which makes it possible to use the C++ API from Python. Be aware of GIL though!

Another fun project is vapoursynth-ts which is a WIP PoC of VapourSynth bindings for TypeScript I mainly worked on for learning how to do C++ NodeJS extensions.
