Like, to offer a download option for my viewers.
Are you asking if its legal? If so, then yes, absolutely. Unless you used music you don’t own the rights to etc.
Oh ok, that’s great! Thanks for the answer! 
The same applies for any copyrighted images or video.
As long as you own the rights to the video and sound, I’m not sure why you think there would be a legal issue making a torrent out of it.
