In 2003 or 2004 I had a job doing video installations with Linux systems in a variety of museums. That was the first time I learned about FFMpeg. Used it for everything, still one of the first things I install on any system, and whenever I need to do anything with video conversion or resizing or taking a slice out, I use FFMpeg. It is awesome.<p>Although, after all these years I still have to look up every single incantation except for the most basic things.
