The timeline, left to right
The Storyboard page is a single horizontal strip that scrolls sideways. Each card on it is one shot, and its width is just a card; the seconds are printed on it rather than drawn to scale, which keeps a fifteen-second shot from crowding out a five-second one on a phone screen. Empty slots are drawn with a dashed outline so the next card has somewhere obvious to go.
Above the strip sits the runtime meter: planned seconds on the left, target on the right, and a bar between them that fills as cards are added. Drag a card and the meter does not change; change a duration and it does. The whole episode is readable at a glance without playing anything.
What lives on a card
Duration, from four to fifteen seconds. Shot size: wide, medium, close, over-the-shoulder or POV. Camera move: static, push in, pan or handheld. Up to three cast members, each optionally with an outfit, a prop and a voice style. A set. And the line, which is the sentence or two describing what happens in the shot. When the card has been rendered, its take plays in a small preview right on the card.
Cards can be duplicated, which is the fastest way to make a reverse angle: copy the card, flip the shot to over-the-shoulder, swap which character is in the foreground, keep the line.
Rendering in order, or not
Pending cards queue up for rendering as takes. You can render them in order, render the cheapest ones first to check the cast, or render the hardest one first to see if the idea holds. Each take is its own job with its own price, shown on the card before you confirm, so the queue is never a surprise bill.
When every card has a complete take, the join step concatenates them in timeline order into one 9:16 file. Reorder before you join and the file follows the new order.
Scenes become episodes, episodes become series
A timeline belongs to an episode, and an episode belongs to a series. The series carries the recurring cast and the default set, so a new episode starts with the right faces available. Series can be made public, which gives them a page listing every joined episode with a player.
Nothing about the structure is forced. A series can be one episode; an episode can be one card. The timeline is there for when you want more than that.
