Converting a video to a different format can be as simple as this.% ffmpeg -i input.mp4 output.avi

However, what we really need are some video files to test this out. Another trick that ffmpeg has is that it can also record from macOS input devices. You can see which devices ffmpeg can capture from by using -list_devices :% ffmpeg -hide_banner -f avfoundation -list_devices true -i ""
