AviSynth

What is AviSynth?

  • It’s a powerful tool for video post-production.
  • It’s a frameserver, providing instant transfer to other video applications without the need for temporary files.
  • It’s a script system for non-linear editing and video filters and effects.

AviSynth itself does not provide a graphical user interface (GUI). While scripting may at first seem tedious and unintuitive, it 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. You have complete control of everything.

The scripting language is simple yet powerful – basic filters can be combined to create useful and unique effects. It is easy to create a quick script to solve some video problem. It can do much more than that, though: to get an idea, take a quick glance at all the third-party plugins available, or browse the doom9 forum to see what AviSynth users and developers are getting up to lately!

AviSynth takes its name from AVI, a digital media format, and Synthesis, because it creates (synthesizes) a virtual (in memory, not on disk) media file – “generating video and audio data according to the script and feeding it to the application as needed.” (in the words of its inventor, Ben Rudiak-Gould). It could be used as a Video Synthesizer, but this is not its usual function.

AviSynth is free open-source software, under the GNU General Public License GPLv2; see Copyrights.

New to AviSynth – Start Here

  • 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 filters.
  • Script examples – Putting everything together in the real world.
  • AviSynth FAQ – Answers to many common problems.
  • More information (How does it work? When is it useful? Why no GUI? What applications work well with AviSynth?)
  • Some guides explaining the basic possibilities of AviSynth:
    • 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.
    • AviSynth 101 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.
    • AviSynth Basics – another guide for beginners.
    • Introduction AviSynth from AnimeMusicVideos.org. A basic guide about deinterlacing, resizing and some other basic stuff.
    • Introduction basic AviSynth filters from AnimeMusicVideos.org. A basic guide about smoothers, rainbow removal, sharpeners, color adjustment and some other basic stuff.
