I had a fun time trying to remove the heavy breathing from the video.  There is a method using the VLC app that I managed to finally get right after a dozen or more tries.  I wanted to find a setting on the smartphone to record video sans audio but had no luck at all.  I could deny the camera app permission to use the mic but the default Samsung camera refused to load without it.  I may go on a hunt for an alternate camera app, but not today.
