Something like this works I got this code from stack exchange
ffmpeg -i video -c:v copy -af volume=0:enable='between(t,60,100)' out.mp4<br>
i do not want to use the t60 method I want to rather use something like
-ss 00:00:03 -t 00:00:08 but it chops the video up.
I want to just remove audio using 00:00:00
