Product video needs recognisable items throughout motion. Compare Veo and Runway beyond backgrounds and camera style. Labels, lids and reflections can determine usability.
Start with verifiable motion
Choose a slow rotation or simple camera change and document required product views. Supply references; an undocumented back cannot be invented and called accurate.
Add complexity after assessing the simple display. Inspect liquid, glass and metal reflections alongside geometry and apparent material.
Use a revision to assess reliability
Change lighting or background while preserving the product. Record new errors and restoration effort. Multiple variants need maintainable workflows.
Document version, date and access. Consider original imagery with motion alongside fully generated video; which ad shots to film, not generate covers that split.
