That is an exception, sometimes a more amateur footage done on the street without lighting and preperation of an amazing live performance and reaction isnt bad. Also think about it this way. There are 2 videos of the same thing, one is shot on a webcam, other done nicely in HD with good editing. People will view the nicer one more and think more highly of the person then of the other person with a video with low resolution, one thats too dark, maybe a terrible fps, out of focus footage,etc
