Create a 15-second {{ASPECT_RATIO}} explainer for {{AUDIENCE}} about {{CONCEPT}}, based only on the factual sequence {{SEQUENCE}}. Show one stage at a time with clear composition, minimal movement and enough pause for captions to be added later. Keep objects, scale and process direction consistent. Generate no text, numbers, voice, mascot, extra facts or unstated causal link. Avoid rapid cuts, flicker, misleading decoration and shape changes between shots. End with a blank visual-summary frame for post-produced labels.
A teacher or subject reviewer must compare every frame with the source. Add narration, captions and alternative description only after factual approval.
