Prompt Format Drift Split Screen

Create a 12-second educational split-screen from [approved baseline and changed layout]. Hold baseline fixed while highlighting one structural difference in the other panel. End on [evaluation checklist area] left blank for editable text. No invented scores or fake app UI.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
