>>66899390ffmpeg -i filepath\filename.mp4 -ss 00:00:00 -to 00:00:00 -vn -c:a libmp3lame outputfilepath\outputfilename.mp3
-ss 00:00:00 -to 00:00:00 sets the time
-vn is no video
-c:a libmp3lame is for mp3 audio codec cause mp4s use aac
you will have to either add ffmpeg to PATH or cd to the folder you put it in
it's not that hard actually
I can convert the whole damn two hour stream to mp3 in like a minute and it's 109 mb
