In Tony Zhou’s latest video, the question isn’t how editing is done technically, it’s how it feels. What does it mean to feel an emotion, and how much time does that take to register? Breaking down sequences from Hannah and Her Sisters and The Empire Strikes Back, among others, Zhou dives into the intangibles and instinctual particulars of editorial timing. With interview cameos from, among others, Michael Kahn, Walter Murch and Thelma Schoonmaker.
