AviSynth 2.5.8


As we mentioned before, AviSynth does not have a real program interface. This may seem strange to some users, but in fact it allows advanced non-linear editing in a very quick way. The power of this video editing method is that you can manage all your projects in a precise and consistent manner. All scripts can be read by any post-production editor, so it is very well known what filters or tasks were applied to any video file. The used scripting language is not hard to learn, but at the same time it allows you to use complex filters to create a sophisticated palette of unique effects.

Basic Operations

AviSynth 2.5.8 works by faking AVI files. Therefore, any application that can open AVI files can apply all scripts written by you. This application works as a frameserver which means that you can apply your filters on-the-fly. In general, you can easily adjust the look of your videos, but for advanced video editing, it is recommended that programs like Adobe Premiere and Adobe AfterEffects be used.


AviSynth is a very good program if you want to compress video. Many filters are specifically written for tasks regarding video pre-processing. Many other plug-ins can be used to reduce noise, adjust colors and resize your videos. So give it a try and find out whether it works for you or not.


  • Works faster than standard editors
  • Multi-language program
  • Compatible with most media players


  • Takes time to learn how to use it
