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: * You can donate by buying me a coffee: https://buymeacoffee.com/avisynth * You can donate using PayPal: https://paypal.me/avisynth/ === {{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. </p> <p> AviSynth is free open-source software, and licensed under the [http://www.gnu.org/licenses/gpl-2.0.html GNU General Public License GPLv2]. </p> |- | style="vertical-align: top; width:50%; padding-right:2em; padding-top: 1em;" |  === {{ReverseHeading3|New to AviSynth – Start Here}} === __NOEDITSECTION__ * '''[[first script|Your first script]]''' – A guide for total newbies. * '''[[Getting started]]''' – An introductory guide. * '''[[Grammar]]''' – An introduction to the AviSynth scripting language. * '''[[Filter introduction]]''' – An introductory guide to most common AviSynth [[Filter|filters]]. * '''[[Script examples]]''' – Putting everything together in the real world. * '''[[AviSynth FAQ]]''' – Answers to many common problems. * [[More_about_AviSynth|More information]] ''(How does it work?
