Samurai Castle Siege Action

Reference Image:
@image1
[CONDITION DEFINITION]
A cinematic and high-precision historical action short of approximately 15 seconds. Use the person in the reference image as the sole character anchor, maintaining gender, facial features, eye impression, hairstyle, hair color, sense of age, armor structure, color scheme, fabric decorations, and weapons to depict them as the same person. If the reference image is live-action, depict it as high-quality live-action; if it is an animation or illustration, depict it as high-quality animated footage preserving the original lines, coloring, and texture, without changing the art style mid-video. Do not inherit the solid background, standing posture, idle pose, or composition of the reference image.

The setting is a Japanese castle on the verge of falling just before dawn. From the burning castle gate, the mounted samurai from the reference image leads a small group of cavalry in a final charge. The protagonist is always the single reference character at the front. The small group of cavalry acts as a brief auxiliary presence behind or around them.

[OPTIONAL PERFORMER LOOK]
A warrior who is brave and noble, conveying a sense of resolve at the risk of their life. Do not obscure the face too much with smoke or hair, and ensure they are recognizable as the same person even while riding. Armor, fabric decorations, and weapons must not change mid-scene.

[SHOT / FLOW]
0.0–3.5s: Departure from the collapsing castle gate. Use a low wide shot to show the burning gate, crumbling wooden doors, smoke, sparks, and torn flags; the mounted warrior bursts out immediately after the wood collapses. Use short jump cuts to show the eyes, hair, hands gripping reins, weapon hilt, swaying armor/fabric, and hooves kicking the ground in succession.

3.5–8.0s: Rapid acceleration and arrow volley. Follow the hooves and front legs from a very low rear diagonal angle at close range, showing heavy dust clouds. Zoom in on the face to show a sharp gaze forward even amidst intense vibration. Switch to high-speed side tracking, blurring the castle walls, flames, flags, and enemy soldiers. Arrows fall from above and in front; the warrior ducks low to evade. The camera swiftly orbits from front-diagonal to the side for a three-dimensional charge.

8.0–12.5s: Impact and breakthrough at the enemy front line. A row of spears and shields looms ahead. From a low front position, the mounted warrior and horse rush toward the camera at high speed, breaking away to the side just before impact. The warrior does not stop, changing course to plunge into gaps between spears, striking an enemy spear hilt once with force, sending off short metallic sparks. Quickly cut between hooves, eyes, reins, weapon-to-spear contact, armor, horse shoulders, and dust clouds, breaking through the line while maintaining speed.

12.5–15.0s: The aftermath without stopping. Emerging from the dust clouds into the battlefield illuminated by the morning sun. Behind them are the burning castle, collapsed gates, disordered enemy lines, and torn flags. Ahead is the golden sunrise. The warrior does not stop, briefly turning their face or continuing to stare straight ahead. Finally, the camera pulls up and back into an aerial view, capturing the lead reference figure, the small cavalry group, the burning castle, and the sunlit battlefield in the same frame. Do not conclude the outcome of victory or death, leaving a sense of bravery and pathos.

[CAMERA / EDITING]
A very dynamic 8–10 cut composition. Utilize low wide shots of the burning gate, close-ups of eyes, reins, and weapons, ultra-low hoof tracking, high-speed side tracking, rapid frontal approaches, diagonal-to-side orbits, high-speed push-ins at the enemy line, and an ascending aerial view after the breakthrough. Avoid long static shots of the horse from a distance or side. Use short cuts of hooves, legs, shoulders, face, torso, hands, armor, and weapons to express the weight and speed of the cavalry. Use 0.2–0.6s jump cuts for faces/feet, 0.8–1.5s for major actions, and 1.5–2s only for the final shot. Use blurred backgrounds, wind pressure, dust, sparks, hair, and fabric to enhance the sense of speed.

[SOUND]
Do not include BGM. No music, singing, or narration. Sound effects and ambient noise only. Emphasize heavy hoof beats, ground vibrations, the rattling of armor and metal decorations, reins, short metal-on-metal spear impacts, the whistling of arrows, flames, collapsing wood, flags, wind, dust, and distant shouts.

[NEGATIVE]
No text, subtitles, logos, watermarks, real-world family crests, brands, UI, split screens, collages, or the reference image itself; no character sheets on solid backgrounds within the video. Do not increase the number of protagonists or change the lead. Do not change the reference character's gender, face, hair, age, armor, colors, weapons, or art style mid-way. Avoid weapon disappearance, transformation, or duplication. Avoid horse-rider merging, extra legs, or unnatural high jumps. Avoid long-distance static shots, simple lateral movement, long straight runs, silent departures, excessive slow motion, frozen poses, over-the-top fantasy, glowing weapons, mechanical armor, giant fire effects, overly dark screens, low contrast, or muddy smoke. Ensure the character is not buried in fire or smoke.

[CONDITION DEFINITION]
約15秒、シネマティックで高精度な歴史アクション短編。参照画像の人物を唯一のキャラクターアンカーとして使用し、性別、顔立ち、目の印象、髪型、髪色、年齢感、鎧の構造、配色、布飾り、武器を維持し、同一人物として描写する。参照画像が実写なら高品質な実写のまま、アニメ・イラストなら元の線、彩色、質感を保った高品質なアニメ映像として描写し、途中で画調を変えない。参照画像の無地背景、立ち姿、待機ポーズ、構図は継承しない。

舞台は夜明け直前、落城寸前の日本の城。炎上する城門から、参照画像の騎馬武者が少数の騎馬兵を率いて最後の突撃を開始する。主役は常に先頭の参照人物1人。少数の騎馬兵は背後や周囲に短く見える補助的存在とする。

[OPTIONAL PERFORMER LOOK]
勇敢で気品があり、命を懸けた覚悟を感じる武者。顔を煙や髪で隠しすぎず、騎乗中でも同一人物と分かるようにする。鎧、布飾り、武器は途中で変化させない。

[SHOT / FLOW]
0.0–3.5秒：崩壊する城門からの出陣。低い引きで炎上する城門、崩れかけた木門、煙、火の粉、破れた旗を見せ、木材が崩れ落ちた直後に騎馬武者が勢いよく飛び出す。短いジェットカットで、目元、髪、手綱を握る手、武器の柄、揺れる鎧と布飾り、地面を蹴る蹄を連続して見せる。

3.5–8.0秒：高速加速と矢の集中。超低位置の後方斜め追尾で蹄と前脚を至近距離から追い、土煙を強く見せる。顔へ急接近し、激しい振動の中でも前方を鋭く見据える表情を見せる。側面高速追従に切り替え、城壁、炎、旗、敵兵を高速で流す。上空と前方から矢が降り、武者は上体を低くしてかわす。カメラは正面斜めから側面へ素早く回り込み、立体的な突撃にする。

8.0–12.5秒：敵前線への衝突と突破。前方に槍と盾の列が迫る。前方低位置から騎馬武者と馬がカメラへ高速で迫り、直前で横へ抜ける。武者は停止せず槍の隙間へ進路を変えて突入し、武器で敵の槍の柄を一度だけ強く弾き、短い金属火花を散らす。蹄、目元、手綱、武器と槍の接触、鎧、馬の肩、土煙を高速で切り替え、速度を維持したまま前線を突破する。

12.5–15.0秒：速度を止めない余韻。土煙の中から前方へ抜け、朝焼けに照らされた戦場へ走り続ける。背後には炎上する城、崩れた城門、乱れた敵前線、破れた旗。前方には金色の朝焼け。武者は停止せず、一瞬だけ顔を横へ向けるか、前方だけを見据えたまま走り続ける。最後はカメラが後方上空へ引き上がり、先頭の参照人物、少数騎馬、燃える城、朝焼けの戦場を同じ画面に収める。勝敗や生死は断定せず、勇敢さと悲壮感を残して締める。

[CAMERA / EDITING]
非常にダイナミックな8〜10カット構成。燃える城門の低い引き、目元の寄り、手綱と武器の寄り、蹄の超低位置追尾、側面高速追従、正面からの急接近、斜め前から側面への回り込み、敵前線への高速プッシュイン、突破後の上昇俯瞰を使用する。馬の全身を遠景や真横から長時間固定しない。蹄、前脚、馬の肩、顔、上半身、手、鎧、武器を短く切り替え、騎馬の重量感と速度を表現する。顔や足元のジェットカットは0.2〜0.6秒、主要アクションは0.8〜1.5秒、最後のみ1.5〜2秒。背景を高速で流し、風圧、土煙、火の粉、髪、布飾りで速度を強化する。

[SOUND]
BGMは絶対に入れない。音楽、歌、ナレーションなし。効果音と環境音のみ。重い蹄音、地面の振動、鎧と金属装飾の揺れる音、手綱、武器と槍の短い金属衝突音、矢の風切り音、炎、崩壊する木材、旗、風、土煙、遠くの叫び声を強調する。

[NEGATIVE]
文字、字幕、ロゴ、透かし、実在する家紋、ブランド、UI、分割画面、コラージュ、参照画像そのもの、無地背景の人物シートを映像内に出さない。主役を複数人に増やさない。別の人物を主役にしない。参照画像の性別、顔、髪型、髪色、年齢感、鎧、配色、布飾り、武器、画調を途中で変更しない。武器の消失、変形、複製、持ち替えを起こさない。馬や騎手の融合、複製、脚の本数異常、不自然な大跳躍を避ける。遠景だけの騎馬走行、単調な横移動、長い直線走行、静かな出陣、長時間のスローモーション、停止した決めポーズ、過度なファンタジー、発光武器、機械的な鎧、巨大な炎エフェクト、暗すぎる画面、低コントラスト、濁った煙、人物が炎や煙に埋もれる映像を避ける。
