拆解 14 秒手持剑斗的现存提示词

14 秒里要容纳 3 次刀刃接触，而且镜头结束时，下一次进攻仍在运动中。

这就是这份决斗提示词的任务。摄影机留在打斗内部，只看到交锋的片段。两个人入画时已经在奔跑，镜头离开时，他们还有动作没有完成。

现有文本在 SWORDSMANSHIP 部分中途截断，我不能把它当作完整提示词发布。我可以展示保留下来的完整段落，解释其中的指令如何相互依赖。对于截断点之后写了什么，所提供的材料无法支持任何判断。

开头先说明镜头要做什么，再描述它的样子：

SCENE CONTEXT
Dawn duel on raked sand, already under way. Two swordsmen close the last four metres and their blades meet three times in fourteen seconds. The camera lives inside the fight and catches it only in fragments.

最后一句和刀刃碰撞次数一样，都是我需要的。如果完整展示决斗，镜头就变了。摄影机应该从内部经历这场打斗，捕捉画框周围正在发生的交锋。

参考图确定人物、刀和地面：

ACTIVE REFERENCES
@character-toshiro-mabe-formal: man in his forties, black formal robe, dry and unmarked. 100% matches the reference.
@character-ryo-sagi-brown: man in his thirties, brown robe, dry and unmarked. 100% matches the reference.
@prop-mabe-sword: single-edged sword, worn cord wrap on the grip. 100% matches the reference.
@place-sand-ground-dawn: raked sand ground at dawn with a pine line behind it. 100% matches the reference.

“100% matches the reference”是提示词里的指令，不代表生成结果已经做到了完全匹配。这里值得检查的是，我把哪些内容绑定到了图片上：身份、服装、刀柄缠绳和场地。

接着，这些元素被安排到具体位置：

LOCATION MAP
Foreground: sand kicked up at ankle height, drifting across the lens. Midground: the two men, four metres apart on the first frame and closing. Background: the pine line and a row of standing onlookers, soft and small. The camera sits between the two men at chest height, 1.5 to 4 metres out. Colour lives in the materials: pale dry sand, black wool robe, brown hemp robe, cold grey steel, all of it lit warm from one side.

FIRST FRAME / BLOCKING
Both men are already at a full run, mid-stride, weight forward, blades up and travelling. @character-toshiro-mabe-formal enters frame left moving right; @character-ryo-sagi-brown enters frame right moving left. Sand is already in the air. Tight two-shot, cut off at mid-thigh.

首帧里已经能看到动作带来的结果。脚已经扰动地面，身体已经压上重心，刀刃已经在移动。

这给了我检查开头的具体依据。如果两个人站着不动，衣袍也静止垂落，即便脸再逼真，也没有达到文字规定的起始状态。

空间图还分配了景深层次。沙子从镜头近处掠过，打斗者占据中景，旁观者留在后方，显得很小。他们的存在，不应该让这个镜头变成拍观众的镜头。

FORMAT MODE
One continuous shot, the camera holds the take to the last frame. Fast lateral whips inside the shot are camera movement.

OPTICS
Tight two-shot at 63°, opening to 47° as the gap closes. Natural perspective, shallow separation on the near body, deep focus held on the far one.

CAMERA
Handheld at chest height, 1.5 to 4 metres from the bodies, moving with the fight instead of following it. It takes each impact in the frame, whips laterally between the two men, and arrives a fraction late to every clash, so each blow is already leaving as the frame gets there. Focus rides the near shoulder.

这里区分了甩镜和剪切。提示词要求摄影机在横向运动中维持同一个连续镜头。镜头内部出现剪切，就改变了规定的形式。

摄影机还得解决一个时机问题：碰撞要落在画面里，但摄影机又要晚到一瞬，捕捉这一击正在离开的时刻。这是一个很精确的意图。我会把接触和摄影机到达的时间一起判断。画面里全是运动，本身并不能证明这种关系成立。

ACTION
0 to 4 seconds: both men cover the last four metres at running speed and the blades meet the first time, steel on steel, and slide apart.
4 to 8 seconds: the second exchange, closer, with the camera whipping across to the far man as his hips turn into the cut.
8 to 11 seconds: the third clash, the tightest of the three, the two guards locked for a fraction of a second at chest height.
11 to 14 seconds: they break and the next attack is already loading, and the shot ends with that movement still travelling.

每个时间段都在改变交锋。第 1 次接触后，刀刃滑开。第 2 次让摄影机随着远处那个人转髋而甩过去。第 3 次让两把刀的护手短暂相抵。最后一个时间段解除这次接触，进入下一次进攻。

结尾尤其容易被误读。双方分开只是指令的一部分，下一次进攻必须已经在蓄势。如果定格在一个收招姿势，就会丢掉我需要在结束时保留的运动。

PERFORMANCE
Jaws set, lips parted, breath visible in the cold morning air. Eyes stay locked on the other man's hands and hold there. Skin shows pore texture and a film of sweat at the temple, catching the low sun. Fingers reset on the grip between exchanges.

PHYSICS
Every footfall throws sand that falls back under its own weight. Blades carry mass: they swing through and past the body, and the arms follow the steel rather than driving it. Robes lag behind the torso by a beat and settle. Real time at 24 frames per second, a shade faster than life.

大动作发生时，身体还有一些细小的任务。眼睛盯着手，手指重新调整握持，衣袍在躯干动过之后才跟上，沙子落回地面。

这些是写下来的检查项，规定动作里应该包含什么。节选没有给我结果记录，也没有失败生成的账单，所以我不能为它们附上成功率或成本。

目前保留下来的最后几条完整剑术指令是：

SWORDSMANSHIP
The two hands sit apart on the grip, left hand at the very end, right hand under the guard, two fists of space between them. Every cut is driven by the hips turning and the left hand pulling down, and the blade continues out the far side in one motion, finishing in the air past the body.

这一段集中说明了预期的握法和挥斩机制，把 ACTION 中的转髋，与 PHYSICS 中刀刃挥过后的延续运动联系起来。

光线贯穿现存文本：黎明、从一侧照来的暖光、低角度阳光照到汗水。人物参考也确定了衣服干燥、没有伤痕。这些都是可见的要求，但不能替代文档缺失的结尾。

今天，从自己的提示词中挑出一个动作时间段，把它和摄影机、身体运动机制，以及要求的结束状态逐一对照。生成之前，把它们放在一起读。
