Generate a 10-12 second vertical video brief centered on an adult presenter recording a Lunar New Year street selfie narration. Build it with three concrete beats: open with a stabilized phone-selfie frame that establishes the presenter, festival street lights, lantern color, and public celebration mood; move into a short spoken greeting or travel-style narration with natural facial motion, clean lip-sync, small walking or hand movement, and background pedestrians kept softly out of focus; end on a stable smile or sign-off frame that can work for a landing page preview, creator reel, or social cutdown. Keep the camera close enough for a selfie but not distorted, with readable facial expression, steady exposure, warm festive lighting, and continuity rules for mouth shape, eye direction, hair, clothing, and background movement. Keep the presenter look, street setting, props, greeting text, subtitles, and logo areas editable. Avoid real brand names, celebrity references, fixed IP, uneditable readable signage, youth-coded casting, unsafe crowd behavior, political claims, sudden teleport cuts, face flicker, warped anatomy, and unrelated extra scenes.
