» AboutAviSynth




( Diese Seite in flag-germany.gif Deutsch )

AviSynth is a very very powerful tool for video post-production. It provides almost unlimited ways of editing and processing videos. AviSynth works as a frameserver, providing instant and very fast editing without the need for temporary files.

AviSynth itself does not provide a graphical user interface (GUI) but instead relies on a script system that allows advanced 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.

Interested? On this site, you can read more about AviSynth, search the official AviSynth manual, and browse the AviSynth FAQ. Or you can jump straight to the [download page] at SourceForge.

Tips & Guides


Random Musings


Welcome to our [Wiki]! This will hopefully evolve into a compendium of AviSynth tips, scripts, and a (brief) history. Since none of this is going to happen until someone gets the ball rolling, I'll give it a shot by creating a rudimentary index. Feel free to pitch in and help out! Here's a basic [command summary] for working with Wikis.
