FFmpeg is a free and open-source project consisting of various libraries and programs for handling video, audio, and other multimedia files and streams. To be able to use these commands, you'll need to have FFmpeg installed on your system. This is possible because the same commands can also be used to crop. For each example command, the image is cropped using the actual FFmpeg crop command from that example, so you can see exactly what happens when using it.
