Video prompt: Serene 4K UHD video, 12s, 60fps, loopable, medium shot, vertical composition, wise Japanese tea master in simple black kimono, long white beard, gentle eyes. Sitting in minimalist modern tea room: low wooden table, traditional tea utensils, single bonsai tree, sliding glass door with view of cherry blossom tree. Dynamic actions: He slowly picks up a bamboo whisk with one hand, placing it in a bowl of matcha powder; he pours hot water into the bowl with a small teapot, his hands moving slowly and deliberately; he whisks the matcha tea in a circular motion, the bamboo whisk moving quickly, creating a smooth, frothy surface; he stops whisking, placing the whisk on the table, then picks up the bowl with both hands, holding it out in front of him in a gesture of hospitality; he takes a small sip of the tea, then places the bowl back on the table, closing his eyes for a moment in contemplation; a cherry blossom petal floats through the sliding glass door, and he opens his eyes, smiling gently. Lighting: Soft natural daylight, warm ambient light, high contrast, sharp details on tea utensils and bamboo whisk, no text, no watermark. Style: Minimalist, serene, calming aesthetic. --ar 9:16 (Vertical, 1080x1920, YouTube Shorts Standard)
