图1 关键帧:
A medium shot from behind and slightly below of an original young woman in her twenties with long loose light-brown hair,
a simple faded white cotton dress, walking barefoot through waist-high golden grass on a gentle hill just before sunset,
her right hand trailing across the tops of the grass. She is placed on the left third of the frame, cut at the hips by the grass.
Camera low at her waist height, close behind her, tilted slightly up, 18mm wide-angle lens, deep focus, the sky filling the upper half of the frame.
Lighting: the low sun directly ahead of her in the upper right of the frame, warm golden backlight making her hair edges and the grass tips glow,
soft lens flare, pale blue sky above, long shadows falling toward the camera.
Stylized semi-realistic 3D CG rendering, feature-film animation quality. Aspect ratio 2.39:1.中文释义:从身后略低处拍的中景,她赤脚走在齐腰的金色草丛里,右手拂过草尖;人物在画左三分之一,被草丛裁到臀部;腰高贴近、略仰、18mm、深焦、天空占上半部;太阳在画面右上角正对她,暖金逆光勾亮发丝和草尖,轻微光晕,影子朝镜头延伸。
【图生视频 · Seedance】
【素材分工】@图片1 为首帧,锁定人物身份、白裙、草坡环境与逆光方向。
【画风】风格化写实三维CG质感,自然光。
她赤脚在草丛中向坡顶慢慢走去,右手指尖一路拂过草穗的顶端,草穗在她手下弯折又弹起。风从画左向画右吹过,整片草浪起伏,她的发丝在逆光里飘起发亮。镜头在她身后低位轻柔地漂浮跟随,没有颠簸,逐渐从她身后绕到她的右侧,太阳始终在画面右上方,光晕轻轻闪过。结尾停在她侧后方的剪影与远处低垂的太阳上。
【声音】风吹草浪的沙沙声,远处几声鸟鸣,她赤脚踩草的轻响。画外音(女声,耳语,语速很慢):"你也在看着这片光吗?"配乐只有一段很轻的钢琴单音。
【约束】保持人物脸型、发型、服装不变;不出现面部正面特写;太阳位置不变;不要字幕、水印、Logo。
时长:8秒参数:时长 8 秒 | 画幅 2.39:1(平台无此选项时选 16:9)
【检查点】
逆光是否从她前方照来,发丝和草尖是否发亮
镜头是否低、轻、无颠簸,并完成"身后 → 右侧"的漂浮
旁白是否短,是一个问题
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 太阳跑到身后变成顺光 | 写"太阳始终在她前方的画面右上方" |
| 镜头上下颠簸 | 写"像在空中滑行一样平稳" |
| 她转身对镜头 | 写"她始终背对或侧对镜头" |
| 画面过曝发白 | 写"天空保持淡蓝,太阳边缘清晰,人物轮廓有层次" |
练习2:广角仰拍的树下(难度 ★★)
目标:机位放到孩子的高度并向上仰,树冠、阳光与大人一同进入画面。意图:让观众感到孩子眼中的母亲像天空一样大。

【画风】风格化写实三维CG质感,自然光。
男孩赤脚站在草坪上,仰头看着站在橡树下的母亲。镜头在男孩身旁贴近地面,以广角向上仰拍母亲:她的身影高高地立在画面中央,身后是巨大的树冠和穿过树叶的阳光。母亲伸出手,指尖碰到一缕穿过树叶的光,光斑在她手背上晃动。镜头从男孩肩旁轻柔地向上漂浮升起,越过母亲的肩膀,最后望向树冠与太阳。晾晒的白床单在风中鼓起。结尾停在逆光的树冠与闪烁的光斑上。
【声音】树叶沙沙声,床单被风鼓起的啪啪声,远处纱门轻轻合上。画外音(男孩声,耳语):"妈妈,你在哪里?"无对白。
【约束】保持两人脸型、发型、服装不变;镜头只做一次向上漂浮;不要字幕、水印、Logo。

【素材分工】@图片2 为首帧,确定手与溪水的局部构图和光线;@图片3 为尾帧,是最终画面目标;@图片1 仅锁定人物身份与服装,不参考其背景。只生成两帧之间的连续动作。
【画风】风格化写实三维CG质感,自然光。
他捧起的溪水从指缝间流走,他慢慢张开手让水全部落下,然后站直身体,仰起头。镜头从水面低位开始,随着他站起而轻柔地向后漂浮、向上仰起,经过他湿透的手和衬衫,最终仰望白桦林与透过树叶的低角度太阳,他的身影留在画面右侧边缘。一镜到底,运动平滑。
【声音】溪水流过石头的声音,水从指缝滴落的声响,风吹白桦叶。画外音(男声,耳语):"你说过,光会记得我们。"配乐为一段持续的低音弦乐。

|---|---|
| 中途切镜头 | 写"一镜到底,镜头连续上仰" |
| 他的手变形 | 首帧动作只保留"张开手让水落下" |
| 尾帧变成正脸仰拍 | 写"他的身影只在画面右侧边缘,主要是树冠和天空" |

镜头2:镜头切至同一片麦田稍晚的时刻,两人已经站在风车下,女人背靠木桩,男人站在她面前,两人都没有说话。镜头从低处轻柔地绕到两人侧面,逆光让两人只剩金色的轮廓。风车叶片缓慢转动的吱呀声。
镜头3:镜头切至局部,一只手的指尖从麦穗顶端轻轻拂过,向画右移出画面,只剩麦穗在风中摇晃,逆光里浮尘飞舞。镜头低位缓慢向上漂浮,望向即将落下的太阳。风声。

旁白是否连续覆盖三个镜头,不随切镜断开
光是否越来越低、越来越暖
【常见问题与修复】
| 现象 | 修复 |
|---|---|
| 镜头2补出了"走到风车"的过程 | 写"镜头切至稍晚的时刻,两人已经站在风车下" |
| 人物嘴型跟着旁白动 | 约束写"画面中人物不开口" |
| 三个镜头光线方向不同 | 【锁定】强调"太阳始终在画面深处" |

镜头1:镜头在他身后低位轻柔漂浮跟随,他手里拿着旧草帽,走进齐腰的麦田,麦穗扫过他的手背。逆光从前方照来,他的肩膀和发梢被勾成金色。他停下一步,又继续往前。麦穗沙沙声,脚踩干土的轻响。
镜头2:镜头切至局部,他的手把草帽举到逆光里,阳光从草帽编织的缝隙中透过来,在他的手背上留下细碎的光点,褪色的蓝丝带在风里飘动。镜头低位缓慢环绕草帽小半圈。风声变近,丝带拍打的轻响。
镜头3:镜头切至稍晚的时刻,广角极低机位仰拍,他已经站在坡顶的风车旁,草帽戴在头上,身影很小,太阳就在他身旁入画,光晕闪过。镜头从麦穗间向上轻柔漂浮,天空越来越多。风车叶片缓慢转动的吱呀声。
