图1 关键帧:
A close-up of an original eleven-year-old girl with curly auburn hair tied in two loose bunches, freckles, a yellow raincoat,
standing in a dark wheat field at night, her head tilted up, eyes wide open, lips slightly parted, looking at something above and beyond frame right.
She is placed slightly left of center, leaving looking room toward the upper right.
Camera at a low angle from her chest height looking slightly up, 40mm lens, shallow depth of field, the night sky behind her soft and dark blue.
Lighting: a warm golden-white glow falling on her face from above frame right as the key light, as if from a huge light source in the sky,
a faint cool blue moonlight rim on her hair from behind. Fine dust floating in the warm light.
Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.中文释义:近景,原创女孩,仰头、睁大眼睛、嘴唇微张,望向画外右上方;构图偏左,右上留视线空间;胸口高度略仰拍、40mm、浅景深;暖金白光从画外右上方照亮她的脸(证明有奇观存在),冷蓝月光勾头发轮廓;光里有浮尘。
【图生视频 · Seedance】
【素材分工】@图片1 为首帧,锁定人物身份、雨衣、构图与光线方向。
【画风】风格化写实三维CG质感,电影级布光。
女孩仰望画外右上方,慢慢松开攥着雨衣衣角的手,嘴唇微张,屏住呼吸,眼睛一眨不眨。来自画外右上方的暖金色光逐渐变亮,从她的下巴爬到额头,光里的浮尘缓慢飘动,风把她的发丝轻轻吹起。镜头从近景极缓慢地向她的脸推近,始终不揭示她看到的东西。结尾停在她被暖光照满的脸上。
【声音】低沉的风声穿过麦田,远处传来一声悠长而低沉的共鸣音,越来越近,无对白,配乐只有一层极轻的弦乐长音。
【约束】保持人物脸型、发型、服装不变;画面中不出现她所看到的物体;不要字幕、水印、Logo。
时长:6秒参数:时长 6 秒 | 画幅 16:9
【检查点】
画面里是否没有出现奇观本身
脸上的暖光是否来自画外右上方并逐渐变亮
推近是否缓慢、持续
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 模型画出了天上的飞行物 | 约束写"画面中不出现她看到的物体,只有她的脸和背后的夜空" |
| 表情过度夸张、张大嘴 | 改成"嘴唇微张,表情安静,只有眼睛睁大" |
| 光从正面打成平光 | 写"光只从画外右上方来,脸的左侧保持在暗部" |
练习2:雾中逆光与孩子的高度(难度 ★★)
目标:机位放在孩子眼睛的高度,大人只露出腰部以下;手电光束从背后穿过雾,形成逆光剪影。意图:让观众站在孩子这一边,感到大人们在逼近。

【画风】风格化写实三维CG质感,电影级布光。
男孩蹲在前景的倒木后面,只露出上半身,侧脸朝向画右,双手扶着倒木,呼吸急促。镜头固定在离地约一米的孩子眼睛高度。画面深处的雾里,四五道手电光束从树后出现,光束在雾中清晰可见,从远处向镜头方向缓慢扫动,持手电的大人只露出腰部以下的轮廓和晃动的手电,看不到他们的脸。一道光束扫过男孩头顶上方的树干,他压低身子,屏住呼吸。结尾停在他蹲低、光束从他头顶掠过的剪影上。
【声音】无配乐,远处踩断树枝的声音,此起彼伏的低声呼喊听不清内容,男孩压抑的呼吸声,风吹松针的沙沙声。
【约束】保持男孩脸型、发型、服装不变;大人们不露出脸,只有腰部以下和手电;镜头不移动;不要字幕、水印、Logo。
时长:8秒参数:时长 8 秒 | 画幅 16:9
【检查点】
机位是否保持在孩子高度,大人是否只露出腰以下
光束是否在雾里成形,并从背后指向镜头方向(逆光)
男孩是否清楚地做了"压低身子"这一个动作
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 大人的脸出现在画面里 | 写"持手电的人只露出腰部以下,上半身在画面上沿之外" |
| 没有光束,只有光点 | 加"雾很浓,每一道手电光在雾中形成清晰的光柱" |
| 男孩被光束直接照亮 | 写"光束只掠过他头顶上方,他始终在暗部成为剪影" |
练习3:一镜多调度(难度 ★★★,首尾帧)
目标:不切镜头,靠人物走位和摄影机后退,在一个镜头里从大全景变成"前景近景 + 背景人物"的双层构图。意图:让观众感到妈妈已经知道了,但还没说出口。

plain light-grey background, even soft studio light from the front. Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.图3 首帧:
Using the characters from image 1 and image 2: a deep-focus wide shot of a cluttered family kitchen in the early evening.
The mother stands at the sink in the background on the right, back half-turned, drying a plate.
The boy has just come through the back door in the far left background, his sneakers muddy, holding the screen door.
Camera at the boy's eye level, about one meter high, 28mm lens, deep focus so both are sharp.
Lighting: strong warm sunset light pouring through the back door behind the boy, creating a backlit silhouette edge and a visible beam of dust,
a warm practical lamp above the sink. Keep the faces, hairstyles and outfits exactly as in image 1 and image 2.
Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.图4 尾帧:
Using the characters from image 1 and image 2 and the same kitchen and lighting as image 3:

【素材分工】@图片3 为首帧,确定厨房布局、逆光与大全景构图;@图片4 为尾帧,是最终画面目标;@图片1 仅锁定男孩身份与服装;@图片2 仅锁定母亲身份与服装。只生成两帧之间的连续动作。
【画风】风格化写实三维CG质感,电影级布光。
男孩放开纱门,从画面深处沿着画左一侧向镜头走来,脚步放轻,手里攥着指南针。镜头随着他的接近匀速后退并略微右摇,让母亲始终保留在背景右侧,画面从大全景变为男孩的中近景与背景母亲的双层构图,一镜到底不切镜头。母亲在背景里继续擦盘子,在男孩经过她身后时动作慢下来,最后停住,转头看向男孩的后脑勺。门口的落日逆光在男孩身后留下尘埃光束。
【声音】无配乐,纱门弹回的吱呀与轻碰声,水龙头的细流声,盘子与毛巾的摩擦声停下,屋外远处一声狗叫。
【约束】保持两人脸型、发型、服装不变;一镜到底,不切镜头;母亲只做擦盘子、停手、转头这些小动作;不要字幕、水印、Logo。
时长:9秒参数:时长 9 秒 | 画幅 16:9
【检查点】
是否真的没有切镜头,景别是在镜头内变化的
尾帧是否形成"前景男孩、背景母亲"两层,两人都清晰
母亲是否只做小动作,没有抢主动作
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 中途切成了近景 | 加"一镜到底,镜头连续后退,不切镜头" |
| 母亲也向前走 | 写"母亲始终站在水槽前,不离开原位" |
| 背景母亲虚掉 | 写"深焦,前景男孩与背景母亲同时清晰" |
| 镜头后退时晃动 | 写"镜头像在轨道上平稳后退" |
练习4:先反应,后揭示(难度 ★★★★,多镜头)
目标:用三个镜头完成"脸 → 奇观 → 脸"的结构,揭示镜头里人物极小。意图:让观众感到这对父女找到了传说中的东西。

图1 角色定妆:沿用练习2 图1(男孩)。
图2 场景:
Empty old wooden barn at night during a power outage, rain outside, hay bales stacked on the left, a wooden ladder to a hayloft,
thin gaps between the vertical wall planks, a large double door slightly ajar on the right, an old oil lantern hanging from a beam, unlit, no people.
Wide shot at about one meter above the floor, 24mm lens, deep focus.
Lighting: harsh white car headlights from outside shining through the plank gaps and the door gap, cutting sharp parallel beams through dusty air,
everything else in deep blue darkness. Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.图3 镜头3关键帧:
Using the character from image 1 and the barn from image 2:
a low-angle close-up of the boy kneeling in the hay, looking up toward frame right with wide eyes and parted lips,
a soft warm glow on his face from the lantern he has just lit beside him, a thin white beam from the plank gaps crossing behind his head.
Camera low at his chest height looking slightly up, 40mm lens, shallow depth of field, the hayloft beams soft above him.
Keep the face, hairstyle and outfit exactly as in image 1. Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 16:9.【多图生视频 · Seedance】
【素材分工】@图片1 锁定男孩身份、红色卫衣与指南针,不参考其背景;@图片2 仅参考谷仓布局、木板缝光束与色调,不作为首帧;@图片3 仅作为镜头3的构图与光线参考。
【画风】风格化写实三维CG质感,电影级布光。
镜头1:固定机位在离地约一米的高度,从谷仓内拍向半开的大门。门外雨中,两个大人的身影只露出腰部以下,穿着雨靴,手电与车灯的白光从门缝和木板缝射入,在扬起的灰尘里形成锋利的平行光束。他们在门口停了一下,又走开了。雨声,车辆发动机低沉的怠速声,模糊不清的大人说话声。
镜头2:镜头切至谷仓深处的全景,男孩从草垛后爬出来,跪着向镜头方向慢慢爬近,穿过一道道木板缝光束,光束依次扫过他的肩膀。镜头随他的接近平稳后退,从全景变为他的中近景,一镜到底不切镜头。他在一盏旧油灯旁停下,划亮火柴点燃油灯。雨打屋顶声,火柴划燃的一声。
镜头3:镜头切至仰拍近景,男孩跪在干草上,油灯暖光照亮他的脸,他抬头望向画外右上方的干草阁楼,眼睛睁大,嘴唇微张,然后慢慢把一根手指放到嘴唇前,像在对画外的什么说"嘘"。镜头极缓慢地推近他的脸。雨声变远,只剩油灯火苗的轻响和一声很轻的、像小动物的鼻息。
【锁定】光线:门外车灯的冷白光束从画右进入,油灯暖光只出现在镜头2结尾和镜头3;男孩:黑色乱发、红色卫衣、牛仔裤、胸前指南针;机位在镜头1和镜头2都保持在孩子眼睛高度。
【声音】雨声贯穿;镜头1有发动机与模糊人声;镜头2有火柴声;镜头3声音变稀,只剩火苗声与一声轻柔鼻息,无对白,无配乐。
【约束】保持男孩脸型、发型、服装不变;镜头1大人不露出脸;画面中不直接出现小鹿,只用声音暗示;不要字幕、水印、Logo。
时长:14秒参数:时长 14 秒 | 画幅 16:9 | 负载:3 个镜头含 1 个单镜头调度与点灯动作,属于"有挑战"档;失败时把镜头1单独生成
【检查点】
六维是否都落地:反应近景 / 广角深焦 / 孩子高度与纵深 / 逆光光束 + 暖光照脸 / 后退调度与缓慢推近 / 先反应不揭示
镜头2是否在一个镜头内从全景变为中近景
镜头3的"嘘"是否清楚,小鹿是否没有被画出来
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 镜头3画出了小鹿 | 约束重复"不出现动物",正文只写"望向画外右上方" |
| 镜头2爬行时肢体变形 | 把"爬"改成"弯着腰快步走近",减少四肢接触地面 |
| 火柴和油灯难以生成 | 改成"他打开一只小手电,暖色光" |
| 镜头1大人进入谷仓 | 写"大人始终站在门外,没有进门" |
