What kinds of products does this work for?

The useful predictor is not the category, it is whether the product has a surface that does something under moving light. Metal, glass, stones, gloss packaging, glaze and foil all change as the light travels across them, and that change is exactly what a still photo cannot show and a moving camera can. A gold clasp, a faceted stone, the condensation on a bottle and a foil-stamped label all gain far more from ten seconds of movement than they do from a sharper photograph.

Which categories gain most

Nitaris publishes worked examples for the three categories where that effect is strongest — jewellery, watches, and food and drink — but the mechanism is not category-specific, and cosmetics, fragrance, accessories, homeware and most packaged goods behave the same way. If your product is hard, has a defined silhouette and reflects or refracts anything, it is in scope.

Where it works least well

The weaker cases are worth naming honestly. A product whose value is printed information — a book cover, a boxed board game, anything a buyer reads rather than looks at — gains little from a camera move, because the thing being sold is legible in one flat frame already. Soft goods like clothing are a partial case: the material reads well, but garments are judged on how they hang and fit, which is a body's job rather than a lighting setup's.
