Hello everyone! I have been hosting this wiki for a long time. I have been hosting it since around 2010 (from Richard Berg). Although the content is maintained by several people, and I'm very grateful for their time, the hosting costs a lot of money. If you are happy with the site, please make a donation! I would be very grateful and we can keep this site alive:

=== {{ReverseHeading3|What is AviSynth?}} === __NOEDITSECTION__
AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a [[frameserver]], providing instant editing without the need for temporary files.
<p>
AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced [[NLE|non-linear editing]]. While this may at first seem laborious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.
