The best method to accomplish this to buy your family member a good hearing aid.
Because if you fix the video's for one person, the others that hear well may not like the video's sound. That is not a help to them anyway, because they still will not hear well in the outside world.
So getting them a good hearing aid with options they can set, seems like a better solution or some how cure their hearing problem.
