VapourSynth - Avisynth-inspired video processing framework, 21st century rewrite
- przemoc 13y agoI 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 (taken from https://github.com/vapoursynth/vapoursynth/blob/master/doc/about.rst https://github.com/vapoursynth/vapoursynth/blob/master/doc/a...) 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.
