I just realized that I haven't submitted info about VS at HN when I discovered it back then, so I'm fixing it right now. :)

About page gives good idea what it is and how it differs from Avisynth.

  VapourSynth is an application for video manipulation. Or a plugin. Or a
  library. It's hard to tell because it has a core library written in C++
  and a Python module to allow video scripts to be created.  It came to be
  when I started thinking about alternative designs for Avisynth and most
  of it was written over a 3 month period.  The software has been heavily
  inspired by Avisynth and aims to be a 21st century rewrite, taking
  advantage of the advancements computers have made since the late 90s.
  The main features compared to Avisynth are:
  
   * Multithreaded - Frame level multithreading that scales well
   * Generalized Colorspaces - New Colorspaces can be specified at runtime
   * Per Frame Properties - Additional metadata can be attached to frames
   * Python Based - The scripting part is implemented as a Python module
     so you don't have to learn a special language
   * Support for video with format changes - Some video just can't stick
     to one format or frame size. VapourSynth can handle any kind of
     change
   * Compatible with a large number of already existing Avisynth plugins

Mind that it is still WIP. It's not complete Avisynth drop-in replacement, but it's close as possible, yet diverges whenever things can/should be done better. It's mostly ABI-compatible for Windows Avisynth plugins.
