Spreadsheet Hidden Row Subtotal Sequence

Inputs: [spreadsheet application/version], [small sample table], [filter state], [manually hidden rows], [formula]. Explain how the supplied subtotal formula treats filtered and manually hidden rows in the specified spreadsheet application. Check the documented function variant before asserting behavior. Separate zero, blank and excluded rows and avoid presenting a visible-row count as a total-record count. Produce a 12-second worksheet animation toggling row visibility while showing the formula variant beside the result. Adapt the presentation to [audience] and [tone]. End with a concrete check of the defining task detail against the inputs.

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.
