Thumbnail Test Promise Alignment Sequence

Inputs: [three thumbnail concepts], [video transcript], [test plan], [audience]. Check whether each thumbnail test variant makes a promise the actual video fulfills. Link visual claims to transcript evidence, distinguish curiosity from a false reveal and keep the video unchanged across the planned test. Do not invent click-through results or platform experiment capabilities. Produce a 15-second storyboard comparing three honest opening thumbnails against the same supplied video moment. Adapt the presentation to [audience] and [tone]. Check the defining task detail against the inputs before finishing.

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.
