Composite scenes
A composite scene is several shots in sequence inside one script scene — each shot with its own renderer, prompt and duration. It is how a forty-second passage stops looking like one forty-second clip.
Splitting a long scene into shots, giving each a different renderer, and previewing the result before rendering.
When to use one
Long scenes. A single generated clip holding for thirty seconds drifts and repeats; three ten-second shots — say a Ken Burns establisher, a stock cutaway, then an AI Video beat — reads as deliberate editing. The Direction agent will often propose composites for long scenes on its own.
How shots work
Each shot carries its own renderer, prompt and duration, and the shot durations add up to the scene length. Any renderer can be a shot except Composite itself — composites do not nest.
Cost
A composite costs the sum of its shots, each billed at its own renderer’s rate, plus narration for the scene. Mixing a cheap renderer into a long scene is one of the most effective ways to stretch a monthly budget.
