Open Source Multimedia Software

I frequently look for reference of Open Source Multimedia Software that at times I may require or as to give my friends some pointers on where to start with Graphics and Multimedia creation with Free and Open tools. To keep things short and sweet I had put together a list of tools that fit such criteria and yet still stay free and open source.
