Avanti is powered by Gui4Cli
gui4cli.com and by its own additional dll's which are all written in C and C++.
Therefore Avanti is small
and relies only on the basic Windows OS resources.
It should run without problems on Windows XP and Vista.
   
Notes for Windows 7
and 8 users.
(updated)
Avanti GUI is a free front-end for FFmpeg with the option to insert Avisynth as pre-processor.
It offers user friendly control over all basic and advanced FFmpeg options. A number of template examples are included. No need to be familiar with Avisynth to use the predefined Avanti/Avisynth pre-processor options. Avanti doesn't installs itself and runs from any arbitrary folder. No adware or internet access.
