An act strip, large contextual intertitle and transport form a right-hand column. Scene reels sit above the picture; the output, footage and orchestra-pit entrance sit below. Secondary cue sheets replace the control column and retain a narrow picture at left. The scene picker uses miniature bordered intertitles. Intensity stretches the figure’s cast shadow; Combat throws the façades into a harder lean and spills red beyond the picture. The pit is an organist’s inked cue sheet with drawn and pushed atmosphere stops. Chase adds a pursuing silhouette; Mythos bends the skyline beneath a vast tentacled cast shadow; Sanctuary lights the windows. The held telephone and firing cue occupy the transport row, leaving the watcher visible. The secondary picture crops deliberately to the watcher. The secondary frame keeps its own viewport-sized height, so a tall cue sheet cannot stretch the crop into empty sky.", "primary": [ "C01", "C02", "C03", "C04", "C05", "C07", "C17", "C18", "C20", "C22", "C24", "C33" ], "secondary": [ "C08", "C09", "C10", "C11", "C12", "C13", "C14", "C15", "C19", "C23" ], "tucked": [ "C06", "C16", "C21", "C25", "C26", "C27", "C28", "C29", "C30", "C31", "C32", "C34" ] }, "phone": { "composition": "A cropped, tinted expressionist frame with the current reel title sits above the intensity film edge and the large intertitle.
