【品牌广告】我用AI制作了一支原创饮料TVC：从产品设定到最终成片

没有真实产品，也能拍出一支完整TVC？这次我从零创造青梅气泡饮，用AI完成人物、场景、分镜、配音与最终成片。

一起来看一下成品：

那么接下来，按照我的思路和步骤，你也可以做出这样的作品，一起来实操吧~

一、创造产品与故事

故事的核心非常简单（这是修改过后的故事了，先前的故事可以看我提取出来的聊天记录）：

小时候，一颗青梅落在男孩和女孩中间。男孩先拿到青梅，却在上面轻轻敲了两下，然后推给女孩。后来，两个人在外婆的带领下，一起制作青梅汁。

多年以后，女孩赶到一家即将关闭的旧小卖部。柜台后的男生在一瓶青梅气泡饮的瓶盖上敲了两下，再把饮料推到她面前。

女孩听见熟悉的“嗒、嗒”，认出了眼前这个人，正是小时候把最后一颗青梅留给她的男孩。

产品并不是生硬地插进故事，而是承担了连接过去与现在的作用。

完善后的剧本如下：

剧本.rar（这是修改后的完整故事）

二、制作人物与场景资产

确定故事以后，大家可以先将剧本交给AI让AI先分析一下，

随后去制作成年男女主的人物资产。

我会先在网上寻找合适的面部参考图，

然后让AI分析人物的脸型、五官、发型和整体气质，再将这些特征整理成文生图提示词。

这里需要特别说明：我没有直接拿参考人物做图生图。参考图只用于提取面部特征，最终人物仍然通过文生图生成。

我给AI的要求包括：

根据参考图提取人物的面部特征，重新编写适合Midjourney V8.2的精简英文提示词。人物使用纯灰色摄影棚背景、标准三点式布光、完整全身正面定妆照，并保持自然的成年人身体比例。

Midjourney提示词一定要精简。至少在我这次测试中，提示词写得越长，模型越容易忽略真正重要的部分，服装、年龄、比例和气质也更容易跑偏。

我生成的提示词如下：

男生：

Full body cinematic casting portrait, naturally handsome 23 year old Chinese man, balanced oval face, smooth jawline, calm almond shaped eyes with subtle double eyelids, straight nose, soft natural pink lips, clean warm ivory skin, no moles or freckles, clean shaven, fluffy layered short black hair with light fringe naturally parted across forehead, calm neutral expression, direct relaxed gaze, closed lips, no smile.

original full-body film casting portrait of a 26-year-old adult Chinese woman from a southern small town, quiet fresh bittersweet first-love presence, delicate long oval heart-shaped face, full forehead, soft narrow jaw, small rounded chin, large calm almond eyes, subtle narrow double eyelids, fine straight brows, slim straight nose with a rounded tip, natural medium-full dusty-rose lips, warm fair skin with real pores and faint freckles, black collarbone-length straight hair in a loose low ponytail, wispy center-parted strands, restrained neutral expression, ivory linen short-sleeve blouse, muted young-plum green A-line midi skirt, thin caramel leather belt, small brown crossbody bag, off-white canvas sneakers, exact natural 7.5-head adult proportions, balanced torso and legs, realistic head size, relaxed arms, perfectly front-facing, centered head-to-toe, seamless warm gray studio, soft daylight, 85mm cinematic casting photography, realistic skin and fabric texture --no child, celebrity, glamour makeup, oversized eyes, tiny head, elongated legs, fashion-model proportions, side pose, cropped feet, text, logo, props --ar 2:3 --hd

确定成年男女主后，我把生成结果重新交给AI，让它根据成年角色反推两个人小时候的形象。

儿童角色需要继承成年角色的核心辨识度，例如眼型、脸型、发色和整体气质，但不能只是把成年人的身体缩小。年龄、头身比例、面部软组织和神态都要重新设计。

儿童服装也一定要更换，不能直接照搬成年角色的服装，否则看起来会像同一套衣服被缩小了。

提示词：

将我上面给的人物改成小孩子形象的提示词 ，不要穿图片中的服装，服装你要重新设计一下 不要穿图片中的服装，服装你要重新设计一下
