ffmpeg cheat sheet.

Linux users are probably already familiar with this tool, Windows users probably less so.

ffmpeg is a cross-platform command line tool that can convert just about any format of audio/video/image to just about any other format. It can extract and insert audio from your video, break your video up in to a series of images and even compile images in to a video. Whatever you can think of to do with your multimedia files, ffmpeg can more than likely handle it.

But how to use all of this command line conversion goodness? CatsWhoCode has a pretty good cheat sheet.
