AviSynth 2.6.0 alpha 5

Updated: 21 Sep 2013

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.

How to use AviSynth :

There are some really great programs that support AviSynth or utilize it behind the scenes.

• The most well-tested application is VirtualDubMod. It has a great built in editor that allows you to edit scripts and test the result with a keypress. The easiest way to create a script is to create a simple script, open it and enter Tools/Script Editor (or press Ctrl+E). Now you can edit your script and press "F5" to see the result in the main window.

• The best GUI solution is StaxRip. It provides complete integration with AviSynth and very powerful GUI's for creating scripts. It provides visual cropping, resizing and many filters. It is able to store the settings for later use so you can reuse the scripts. A definate must-try!

• Another powerful, GUI-like approach is AVSGenie. It generates scripts, and allows you to very easy adjust filter parameters visually, and see your result instantly. This is a program with very big potential - only problem for now that it isn't capable of reading scripts, so you can re-edit them.
