Halfway through an AI video, with dozens of nodes on the canvas, "which shots does this film have, and which ones are still missing" gets surprisingly hard to answer. DOTV's storyboard is the same canvas wearing a different face: the canvas spreads things out by position, the storyboard stacks them into columns by type — images, video and audio each get a column, and the shot order is plain to see. The toggle sits at the right end of the top row of the left panel (see 1.4). This section walks you around the screen — how many columns there are, what sits in a column header, what a card is made of. How to work in it (the detail panel, editing in place, filters, key elements, order and references, bringing things into chat) is chapter 11.
