Variable Frame Rate Captions Film

Create a 15-second caption-sync teaching clip from [approved original footage and timed cue comparison]. Show the three actual checkpoints with separate timing overlays; keep the footage speed unchanged. End on the measured drift pattern and avoid fabricating a corrected export.

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.
