Being able to use FFmpeg.exe without referencing its location or copying it into the folder you’re operating in is a huge piece of simplicity. Once FFmpeg is added to your system, path simply calling “ffmpeg” will work as a standalone.

To add FFmpeg into your system path search “edit the system environment variables” and click on the result

Now click on “Environment Variables” button at the bottom

Find the “Path” variable and click edit

Click new and add in the path to your FFmpeg.exe it all depends on where you put it (C:\ffmpeg\bin) etc etc

Once added click ok and test if it works by typing “ffmpeg” into CMD
