AI Video Prompt: Rainbow Cream Piping Decoration in Glass Cup Macro…

Create a single continuous ultra-realistic macro food video in vertical 9:16 format. Show a transparent round glass container placed on a surface in a softly lit indoor environment. A metallic silver piping nozzle is positioned from the top center and slowly releases thick colorful cream into the center of the empty glass container. The cream contains visible pink, yellow, and green sections and forms smooth folded ridges as it is piped. The nozzle moves in a controlled circular motion, gradually building a layered rainbow cream swirl. Keep the camera completely static in an extreme macro close-up shot with shallow depth of field, realistic glass reflections, detailed cream texture, natural shadows, and cinematic food photography lighting. The action must happen continuously without cuts. End with the nozzle lifting away and leaving a finished colorful cream swirl with a small peak on top. Maintain exact object placement, realistic food physics, and natural material behavior. No extra characters, objects, text, logos, or scene changes.
