Setting the script, struggling completely on how to set this up.
If you check in the bin folder you should have 3 files, you want ffmpeg.exe. Take it out of that folder and place it somewhere safe where you're not going to delete it. When you've done that navigate to where you've put it and hold Shift + Right click on ffmpeg.exe and a menu should appear, click on 'copy as path'. Go back to auth.json and paste the value between "" next to FFMPEG_PATH. Finally replace all of the \ with /
