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 WXP, Vista and Windows 7.
   
Avanti is a 32-bit (x86)
application and need to be
set up accordingly on
64-bit OS' (not tested).

Avanti GUI is a free front-end for FFmpeg with the option to insert Avisynth as pre-processor.
It can be used with almost all Windows OS builds of FFmpeg. 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.

Avisynth ...
  
Although optional, we highly recommend to install Avisynth (version 2.5.7 up)
to take advantage of all built-in Avanti/Avisynth options. You can download the latest Avisynth version here
  
The subtitle option requires you have the "VSFilter.dll" plugin in your Avisynth plugins folder. You can download this plugin here
  
7-ZIP ...
  
The Avanti package and some of the FFmpeg builds are packed with 7-Zip.

Support ...
  
For questions and suggestions related to the usage of the Avanti GUI you can
post a message at the Avanti support thread at the videohelp.com forums.
Note that the developer of Avanti may not be able to answer questions that
are related to specific FFmpeg codecs and their command line options.
v. 0.6.5 - (C) 2007-2012
Avanti analyses the FFmpeg console output to interpret and re-arrange its data.
It needs "keys" to do this but because FFmpeg is under continuous development, small changes could brake the functioning of Avanti, partly or even totally.
Just for your information here's the last FFmpeg version that we were able to
check out for this Avanti 0.6.5 release;
  
ffmpeg version N-36785-g4cef928
  
Please report if you have issues with newer versions.
