==What is AviSynth?==
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.<br>
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 tedious 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.<br>

=== New to AviSynth - start here ===

* '''[[first script|Your first script]]''' - A guide for total newbies.
* '''[[Getting started]]''' - An introductory guide for getting started with AviSynth.
* '''[[Script examples]]''' - Assorted examples for putting everything together in the real world.
* [[Filter introduction]] - An introductory guide to most common AviSynth filters.
* Some guides explaining the basic possibilities of AviSynth:
** [http://www.doom9.org/capture/postprocessing_avisynth.html Analog Capture guide]. The AviSynth part of the capture guide is about what filters can be used to enhance the quality of the capture. It discusses things like deinterlacing, denoising, cropping and resizing and color adjustment. Which makes it really useful to learn about some of the capabilities of AviSynth in a schematic way.
** [http://www.l33tmeatwad.com/avisynth101 AviSynth 101] [http://web.archive.org/web/20141018100556/http://www.l33tmeatwad.com/avisynth101 mirror] - A guide by l33tmeatwad, it includes mostly current information on software setup, video basics, importing videos, handling audio, using filters and other useful information.
** [http://salp.wikia.com/wiki/AviSynth_Basics AviSynth Basics] - another guide for beginners.
** [http://www.animemusicvideos.org/guides/avtech/avisyntha.html Introduction AviSynth from AnimeMusicVideos.org]. A basic guide about deinterlacing, resizing and some other basic stuff.
