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.

ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file| ruby '2.7.1' | |

| * In order to show a historical backdrop, big conferences (RubyKaigi, RubyConf and Euruko) are also listed. About the venues of such conferences, general English notations are adopted, in my hope. | |
