Introduction
From time to time you will need to convert media from one format to another. This is sometimes done to use more free and less patent offending codecs or it is sometimes done for compatibility.
MEncoder
MEncoder is a sister application of MPlayer. A short tutorial can be found here: https://help.ubuntu.com/community/MEncoder
FFmpeg
FFmpeg is a video and audio converter which can be installed from the Universe repository. It is a command line application, although there is a graphical front-end interface called WinFF which can be installed. WinFF is not in the official repositories, and is installed from a .deb file which can be downloaded from here (see InstallingSoftware for more information on installing .deb files). Documentation on how to use FFmpeg can be found here.
Avidemux
Avidemux is a video editor for simple cutting, filtering and encoding tasks. sudo apt-get install avidemux.
