| + | |
| − | 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 [[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.
