wondering is there any software on Fedora 31 that will allow me to edit the mp4 to
increase the volume. I doubt that this is that easy, but I still thought that I would give
it a try.

Not really OT since it is a question about usage of utilities under fedora.
I'm sure there are command line options. However, I've been using HandBrake from
rpmfusion quite
a bit to add Chinese subtitles to movies for friends and family.
One of the options when doing this is in the audio area to up the gain. I've used
this option and it has
served me well.
If you have to increase the gain significantly, the SSN--signal to noise ratio--is
likely to take a beating. Try it and
see. --doug
