時長與鏡頭：約 15 秒四段：開唱 → 說唱快切 → 街舞 → 慢下來的走心收尾。這是標準的"短影片 MV"結構：前面越燃，最後那句慢下來的歌詞越打動人，"伴奏戛然而止 + 定格笑容"就是情緒落點。

怎麼填變量：三句歌詞都是變量，建議每句 8–15 個字、押韻、口語化，口型更容易對上。人物的反差可以換成"70 歲爺爺跳霹靂舞""一位穿漢服的姑娘打碟"。做品牌趣味廣告時，可以讓最後一句歌詞變成品牌口號。

常見失敗與調整：

• 奶奶越跳越年輕：在每段都提到"銀髮""皺紋"，負面提示詞寫"年齡變年輕"。
• 街舞動作肢體扭曲：把舞蹈段縮短到 3 秒，只保留"律動 + 定格"兩個動作。
• 歌詞口型對不上：句子縮短，並寫"吐字清晰、語速中等"。

16:9 horizontal screen, street rap MV style, neon purple and blue cool tones, explosive cool and fierce atmosphere. 0-3 seconds: Medium shot push-in, city street night scene with flashing neon lights, an 80-year-old silver-haired woman stands in front of a graffiti wall, short silver-white hair styled in a neat slick-back, distinct square face contour, sword-like eyebrows slanting towards the temples, eyes sharp like electricity, wrinkles at the corners of her eyes like badges of time, a confident smile on the corner of her mouth, wearing a black leather jacket over a white printed T-shirt (large black letters "YOLO" on the chest) + black cargo pants + white high-top sneakers, a thick gold chain necklace around her neck, silver bracelet on her wrist, holding up a microphone with both hands, strong drum beats of the BGM start, the old woman's eyes sharpen, and her lips open to start Rap. 3-7 seconds: Medium shot + close-up switch, the old woman starts rapping, with an extremely strong sense of rhythm, her silver hair flying with her head-nodding movements, one hand holding the microphone, the other hand making gestures to match the rhythm—index finger pointing at the camera, palm cutting the rhythm up and down, making hip-hop gestures, movements are smooth and flowing, eyes sharp and looking directly at the camera, wrinkles vividly jumping with her expression, lips opening and closing rapidly to spit out lyrics: [Rap Lyrics] "Eighty-year-old legs, can jump better than you! Silver hair flowing, this is my pride! Don't call me old, my Flow is better than yours, when you were playing rap, I was listening to disco!" (Fast speed, strong rhythm, fierce attitude) Quick cuts: facial close-ups, hand movements, full-body swaying, side silhouettes, synchronized with the BGM beat. 7-11 seconds: Dance segment, the camera pulls back to show the full body, the old woman starts dancing—first the classic hip-hop bounce, then a neat street dance freeze, followed by a body wave transmitting from the shoulders to the toes, and then a quick footwork workout, movements are clean and sharp, silver hair flies under the neon lights, the leather jacket flutters in the air, she continues to Rap while dancing: [Rap Lyrics] "Legs and feet are nimble, speed is not slow, my lyrics are carved in time! You play with phones, I play with beats, eighty years of life, written into this verse!" (Faster rhythm, stronger tone) Low-angle upward shot + 360-degree surrounding shot, capturing the old woman's cool and fierce dance moves.
