People need an illusion - art forms are based on this. It's like a magic trick - actually sawing a person in half isn't the appeal; its the creation of a universe where a person can exist in two halves without pain or blood. The idea is baby-like, but hopeful, creating stories to escape reality. Because great art is about love, not reality. When you love something, you know its feel, its style, its rhythm - this is its vibration. Reality is interchanging vibrations, but being a product of love, great art's vibration is attractive. Therefore great art must maintain the fiction, the illusion to be "truthful".
To consider film or animation, their illusion is framerate. Everyone knows the pictures are not moving - in film it is not as obvious, but people know the movement is not the same as in real life. Every frame rate has its own rhythm or speed & must fit the "groove" of what its capturing, keeping the illusion in tact. Certain framerates have certain ingrained effects on people based on what they know of, for example relating 16mm film to a home move made during the 1960s, or perhaps an even deeper set effect. This relates to the rest of the film or animation & produces an effect just as much as the music, lighting, backgrounds or sets used do.
This is something I'd like to keep in mind, so I'm just putting it on here.
