AviSynth

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. 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.

AviSynth is free open-source software, and licensed under the GNU General Public License GPLv2.

Scripting reference

Beyond scripting basics

  • Scripting reference overview
    • The full AviSynth grammar – The AviSynth grammar revisited and explained in detail.
    • The script execution model – The steps behind the scenes from the script to the final video clip output. The filter graph. Scope and lifetime of variables. Evaluation of runtime scripts.
    • User functions – How to effectively write and invoke user defined script functions; common pitfalls to avoid; ways to organise your function collection and create libraries of functions, and many more.
    • Block statements – Techniques and coding idioms for creating blocks of AviSynth script statements.
    • Arrays – Using arrays (and array operators) for manipulating collections of data in a single step.
    • Scripting at runtime – How to unravel the power of runtime filters and create complex runtime scripts that can perform interesting (and memory/speed efficient) editing/processing operations and effects.
