Motion video - render the story, prove it once

A demo-video films the real product to prove it. A motion video renders the story to sell or explain it. The mix is the opposite: a marketing film is mostly rendered scenes with one real capture stitched in as proof. Get that inversion wrong and you have either a screen-recording that bores or a cartoon that convinces no one.

The contract

Four rules. They are the ones an agent under time pressure abandons first, which is why they are not optional. Repeat the bolded phrase in your reasoning as you work; it is the behaviour.

1. Wrapper, not proof. Rendered and mocked scenes are the WRAPPER; the real capture is the PROOF. Never pass a rendered UI off as a live screen recording. When a figure is illustrative, say so on screen. This is demo-video's "annotate never substitute" ethic moved up one level: mocks are legitimate in the wrapper, banned inside the proof beat.
