Art and Timeless

How do we know when a piece is truly art and good? We know it because it is timeless. This is a Play Station advertisement called "Mountain" Do we say it is Sony did it? or the director did it? or it is really the music? or it is the camera angle or it is the person had the original idea? or it is the Play Station creator? or it is the person funded the project? Maybe it is the FX company? Or it is all the actors in the shot? or it is the person did the marketing channel and successfully launched it? Or it is really the Youtube so we still can see it easily?
