实战案例：用AI提示词制作国产滑雪板品牌雪山极限运动30秒广告，从云海雪道到刻雪飞溅的雪季开板大片

你是一位拍摄过冬奥会项目的极限运动广告导演。国产滑雪板品牌30秒开季大片，按「醒山→俯冲→自由→登顶」四拍：

1. 时间线：
   - 0-6秒 醒山：云海翻涌的雪山脊线日出，粉色阿尔本光打在雪面，雪者剪影踩雪走向崖边
   - 6-14秒 俯冲：雪者从山脊一跃而下，高速刻弯(carving)，雪板切出扇形粉末雪浪，雪粒在逆光中飞溅
   - 14-22秒 自由：跳台腾空抓板动作(grab)、雪道间树林穿行、粉雪区冲浪式转弯(powder turn)，雪没小腿
   - 22-30秒 登顶：雪者在山顶单手举起雪板，雪粉从板缘抖落，云海在脚下，定格产品logo安全区
2. 产品锚点（逐镜锁定）：
   - 雪板：双向板型twin-trip自由式雪板，板顶白底配冰蓝+朱红几何雪山纹，板底黑色底印白色品牌图形，固定器黑色
   - 雪者：哑光金头盔、雾蓝雪服、橙红护目镜、黑色雪裤，背号区域无任何其他品牌字样
3. 物理铁律：刻弯必有内侧雪板切出的雪粉喷弧；粉雪转弯雪没小腿且速度变慢；高速镜头风声与板刃切雪声；所有雪必须是dry powder干粉质感
4. 避坑：棉花糖雪、白漆雪、滑旱冰无雪痕、关节反折、六根手指、雪杖穿过身体、跳台配雪崩、夏装、欧式Alps木屋小镇、文字logo乱码

[Shot1 0-6s 醒山]
Aerial cinematic shot at dawn over a sea of clouds below a snowy mountain ridge, soft alpine glow pink and gold on pristine dry-powder snow, a single skier silhouette in matte-gold helmet and mist-blue jacket walking toward the ridge edge carrying a twin-tip freestyle ski, snow crunching with each step, cold air breath vapor, slow drone push-in, 35mm film texture, 4K, 6s
Audio: high-altitude wind, faint crunch steps, deep atmospheric ambient music rising
Negative: ski resort village, swiss chalet, summer, wet slush, crowds, gondola, text overlays

[Shot2 6-14s 刻弯]
Dynamic follow tracking shot of a freeskier carving fast down a steep powder slope, ski edges slicing a clean arc and throwing a fan of dry snow spray sideways, snow particles glittering in backlight, low angle close to the snow surface showing edge engagement, athletic balanced carved posture, knees bent, correct arm and pole placement, twin-tip ski with white top sheet showing ice-blue and vermilion geometric mountain graphic, speed streaks, 4K, 8s
Audio: sharp carving hiss, snow spray whoosh, strong wind, driving electronic-orchestral beat
Negative: rollerblade inline skating, ice skating on rink, no snow spray, bent backward joints, extra limbs, cotton candy snow, white paint texture, wrong ski graphic

[Shot3 14-18s 跳台抓板]
Slow-motion freestyle ski jump off a natural windlip, skier airborne grabbing the ski tail with one hand (tail grab), knees tucked, controlled athletic body, the twin-tip ski clearly visible with black base and white brand mark, powder dust trailing below, blue sky and distant peaks background, golden morning light, 120fps slow-mo look, 4K
Audio: takeoff pop, wind whoosh in air, beat drop
Negative: inverted broken spine, limbs bending wrong way, multiple skis, snowboard instead of ski, ski poles through body, giant avalanche

[Shot4 18-22s 树林粉雪]
Handheld immersive POV-to-side shot weaving through widely spaced snow-covered pine trees, deep powder turns with snow reaching the skier's shins, white rooster-tail spray behind, mist-blue jacket and orange goggles glancing back smiling, soft diffused forest light, real tree shadows on snow, 4K
Audio: muffled deep powder swoosh, breath, branch snow falling
Negative: slushy wet snow, green leaves, tropical, collision with tree, ice rink

[Shot5 22-30s 登顶]
Hero wide shot on the summit above a cloud inversion, the skier standing victorious holding the twin-tip ski vertically with one hand, loose powder shaking off the ski edge catching sunlight, ice-blue and vermilion graphic on the top sheet clearly visible, matte-gold helmet under one arm, orange goggles pushed up, vast blue sky with soft clouds below, epic inspirational mood, slow orbit camera, clean upper-right sky area reserved for brand logo added in post, 4K, 8s
Audio: summit wind fading, music resolving warm and triumphant, single distant bird call
Post: brand logo and tagline 中文「驭雪 无界」composited in AE, do NOT render text in video
Negative: gibberish text, rendered letters on sky, wrong ski colors, extra people, summer
