ffWorks (formerly iFFmpeg) is a GUI for FFmpeg, a command line tool used to convert media files between formats. Command line instructions can be very difficult to learn/understand, so ffWorks does all the hard work for you. This allows you to use FFmpeg without detailed command line knowledge.
Peculiarities:
