The video tutorial explains how to find the focus and directrix of a parabola. It introduces a new equation format, X - H^2 = 4P(y - K), to determine these elements. The tutorial covers the significance of the vertex (H, K) and the role of P, which represents the distance from the vertex to the focus and directrix. It emphasizes that the focus and vertex lie on the axis of symmetry and provides steps to calculate the focus and directrix for vertical parabolas.
