Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
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 <http://www.avisynth.org>`_
|
||
|
|
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
