Brought to you by Headjack

FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

Let's start with some basics:

ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file
