this looks great but I can't figure out how to set more
than one event
How do I pass more stuff like 'turn back on at a time'
I tried this:
ffmpeg -y -i withsound.mp4 -c:v copy -af "afade=t=out:st=2,afade=t=in:st=5" done.mp4
but my end video was all silent
I'd like to be able to tell it to turn off audio then back, then repeat
