十五秒西部對決：臉上有疤的可怕牛仔與憨傻無害的牛仔，在街上相距約八公尺面對面

提示詞

15 秒復古西部決鬥，場景中恰好只有兩名牛仔，位於同一個連續場景與同一條連續時間線中。

關鍵的空間與角色連續性：

Cowboy A 是那名臉上有可怕傷疤的牛仔。Cowboy B 是那名無害、頭腦遲鈍的牛仔。兩人轉身後，Cowboy A 必須始終位於畫面左側，面向右方。Cowboy B 必須始終位於畫面右側，面向左方。兩人相距約八公尺，分別站在街道兩側，正面相對。他們在開場時刻之後絕對不能並肩站立。他們絕不交換位置。每個鏡頭都要維持相同的左右決鬥軸線，並遵守 180 度攝影機規則。

每名牛仔恰好擁有一把左輪手槍與一個腰間槍套。Cowboy A 的右側槍套中有一把左輪手槍。Cowboy B 的右側槍套中有一把左輪手槍。兩名牛仔都不能有第二把武器、第二個槍套、備用槍枝或步槍。他們的左手始終空著。拔出左輪手槍後，原本的槍套必須清楚可見是空的。

0–4 秒——建立並鎖定決鬥軸線：

一個對稱的空曠側面廣角鏡頭，拍攝一條空無一人、塵土飛揚的邊疆街道。兩名牛仔一開始背對背站在街道的正中央。Cowboy A 朝畫面左側走三步。Cowboy B 朝畫面右側走三步。他們同時停下，向內轉身面對彼此。

這段結尾時，Cowboy A 必須穩定地位於畫面左側並看向右方，Cowboy B 必須穩定地位於畫面右側並看向左方。兩人之間隔著八公尺的空街道。不要讓他們並肩站立。

4–7 秒——受控的緊張感插入鏡頭：

只能使用三個短暫剪接，同時維持既定的方向：

1. Cowboy A 疤痕累累的臉部極端特寫，位於構圖左側，雙眼看向畫面右側。
2. Cowboy B 緊張、愚笨的臉部極端特寫，位於構圖右側，雙眼看向畫面左側。
3. 他們右手懸停在各自唯一的槍套左輪手槍上方的對應特寫。

接著顯示一個乾淨的垂直分割畫面，其中只包含他們的臉。Cowboy A 佔據左半部，向內看向右方。Cowboy B 佔據右半部，向內看向左方。他們的視線隔著中央分隔線相遇。分割畫面鏡頭中不得出現完整身體或武器。

7–15 秒——喜劇式結尾：

Cowboy B 仍位於畫面右側，驚慌失措地將他的那一把左輪手槍從右側朝左側扔向 Cowboy A。Cowboy B 的右手變得完全空著。被扔出的左輪手槍落在 Cowboy A 前方一公尺處的塵土中；Cowboy A 不接住它，也不撿起它。

Cowboy B 轉身逃跑，朝街道最右側邊緣跑去，帽子幾乎掉落。

15-second vintage Western duel with exactly TWO cowboys, in ONE continuous location and ONE continuous timeline.\n\nCRITICAL SPATIAL AND CHARACTER CONTINUITY:\n\nCowboy A is the terrifying scar-faced cowboy. Cowboy B is the harmless, dim-witted cowboy. After they turn around, Cowboy A must remain on SCREEN LEFT, facing RIGHT. Cowboy B must remain on SCREEN RIGHT, facing LEFT. They stand approximately eight meters apart, directly facing each other from opposite sides of the street. They must NEVER stand side by side after the opening moment. They never cross positions. Maintain the same left-to-right duel axis and obey the 180-degree camera rule in every shot.\n\nEach cowboy owns exactly ONE revolver and exactly ONE hip holster. Cowboy A has one revolver in his right-side holster. Cowboy B has one revolver in his right-side holster. Neither cowboy has a second weapon, a second holster, a backup gun or a rifle. Their left hands remain empty. After a revolver is drawn, its original holster is visibly empty.\n\n0–4 SECONDS — ESTABLISH AND LOCK THE DUEL AXIS:\n\nOne symmetrical wide profile shot of an empty, dusty frontier street. The two cowboys begin back-to-back at the exact center of the street. Cowboy A walks three steps toward screen left. Cowboy B walks three steps toward screen right. They stop simultaneously and pivot inward to face each other.\n\nEnd this beat with Cowboy A firmly positioned on screen left looking right, and Cowboy B firmly positioned on screen right looking left. They are separated by eight meters of empty street. Do not place them beside each other.\n\n4–7 SECONDS — CONTROLLED TENSION INSERTS:\n\nUse only three short cuts while preserving the established orientation:\n\n1. Extreme close-up of Cowboy A’s scarred face on the left side of the composition, his eyes looking toward screen right.\n2. Extreme close-up of Cowboy B’s nervous, foolish face on the right side of the composition, his eyes looking toward screen left.\n3. Matching close-ups of their right hands hovering above their single holstered revolvers.\n\nThen show a clean vertical split-screen containing ONLY their faces. Cowboy A occupies the left half and looks inward toward the right. Cowboy B occupies the right half and looks inward toward the left. Their gazes meet across the center dividing line. No full bodies and no weapons appear during the split-screen shot.\n\n7–15 SECONDS — COMEDIC ENDING:\n\nCowboy B, still on screen right, panics and throws his ONE revolver from right to left toward Cowboy A. Cowboy B’s right hand becomes completely empty. The thrown revolver lands in the dirt one meter in front of Cowboy A; Cowboy A does NOT catch it and does NOT pick it up.\n\nCowboy B turns away and runs off toward the far right edge of the street, nearly losing his hat.
