Create video

A board shows the product. This puts the product in the world: someone in an office takes out their phone, your screens are on it, their thumb moves the flow along, and the audio is the room's own sound.

The model generates the scene and must not generate the interface. Every step below keeps the interface out of its hands. A generative model shown a screenshot will redraw it — right colours, right shapes, invented words — and a demo video with invented words in it is worse than no video.

Boards come from canvases/<slug>/; see sp-canvas for running the canvas and its references/layout.md for the folder rules. sp root prints the tree that ships the scripts below:

KIT="$(sp root)"
B=canvases/<slug>; V="$B/scratch/video"; mkdir -p "$V/out"
