Product placement
mimachha pottery: (a) it ACTS — its interface is operated, it generates or edits something, a visible result comes from it, or someone says what it does for them — the store sells pottery and planters, and the video uses planters for decoration. Removing it would change what happens in the video. (b) it merely APPEARS — a corner watermark, a channel or studio logo, an end card, a credit, a name on clothing, a repost stamp. The store name appears on the building. Removing it would change what happens in the video.
