Commercial production covers TV spots, paid social ads, and long-form branded content. The studios that operate at this level usually own (or have ongoing access to) their own gear, work with established casting and styling partners, and have in-house post.
If you are an agency briefing a commercial videographer, ask about their experience with the deliverables you need. Cinema spec, broadcast spec, and social spec are all different beasts. A team that can deliver all three from one shoot will save you a lot of back-and-forth.
