In The Blink Of An Eye By Walter Murch -

Walter Murch—the legendary film editor and sound designer behind Apocalypse Now , The Godfather Part II , The English Patient , and The Conversation —wrote In the Blink of an Eye as a meditation on a deceptively simple question: Why do cuts work?

He connects the "blink" to the flicker fusion threshold of the human eye. At 16 fps (silent era), the flicker is visible. At 24 fps, it blends into a persistent image. But crucially, 24 fps corresponds to the natural rhythm of the human heartbeat and the blink. in the blink of an eye by walter murch
