This was actually a very frustrating video. The audio engineer goes on to say that we _need_ dynamic range to enjoy the movie, which just no true. I remember when the dynamic range (really, the lack of) debate was going on with regard to music. I can see _how_ the argument would apply to movies and TV, but I really hate when I have to keep adjusting the volume because I don't want to damage my hearing. It's like the worst of both worlds: music remains heavily compressed, while movies have incomprehensible dialog volume.
