Sharing a test prompt: Black Slash Shot 01 | 0—1 | Deep Red Iris Activation 200mm extreme close-up of the right eye alone. The camera is positioned about 45 degrees to the side of Character 1's right eye, level with the pupil, in a fixed position. The frame contains only Character 1's right eye, part of the eyelid, and a few strands of black hair — the left eye or full face must not appear. Focus is locked precisely on the iris texture; an extremely shallow depth of field quickly blurs the tips of the eyelashes and the far-side hair. Both of Character 1's eyes activate at the same instant, but only the right eye is shown on screen: the original pupil color gradually deepens from within into a saturated, trailing dark-red flame-like glow; fine radiating patterns appear around the pupil, then smoothly settle into a deep-red eye-marking structure; the sclera, eyelid, eyelashes and skin continue to match Character 1. A faint dark-red reflection falls on the moist edge of the lower eyelid; the noise of the crowd gradually fades down, leaving only a condensed low-frequency heartbeat and a faint high-frequency ringing. Shot 02 | 1—3.5 | Thunder Draw and Instant Teleport 50mm medium-wide shot from the lower legs up. The camera drops quickly from a mid-height position level with Character 1's waist down to a low position close to the stone floor, maintaining a shooting angle about 45 degrees to Character 1's front side, finally settling with Character 1 stably placed on the right-side golden-ratio line of the frame, body facing left. Focus locks onto Character 1's hands gripping the sword and Character 2's hilt; shallow depth of field keeps the audience stands and the far stone wall continuously blurred. Warm key light forms a Rembrandt-style light-and-shadow structure on Character 1's face, while cool rim light separates the subject along the edges of the black hair and shoulders. Character 1's left hand steadily braces Character 2's scabbard, while the right hand grips Character 2's hilt at a restrained speed at first; the instant the right hand completes its grip, a translucent blue-white flowing electric arc spreads from the hilt across the surface of Character 2's scabbard, showing the blade inside the scabbard charging with electricity in sync — the arc has a bright core, fine branching, and fast, directional movement, and realistically illuminates Character 1's fingers, cuffs, the shadowed side of the face, and the stone ground at their feet. Character 1's draw speed suddenly bursts from slow to explosive, pulling Character 2's blade directly out of the scabbard and swinging it out to the side of the body; during the high-speed phase, only the end of the right arm, the blade, and the background show directional motion trails, while Character 1's torso and facial outline remain sharp. Once Character 2's blade fully clears the scabbard, the arc on the scabbard's surface instantly vanishes, and all the blue-white current flows only along the blade. In the final 0.3 seconds of the shot, Character 1's entire body suddenly produces intense directional motion blur; the body's silhouette stretches into a translucent blue-white flame-like afterimage and vanishes instantly from its original position; the air at that spot briefly collapses inward, dust particles are pushed outward in a ring, and the sash and residual arcs continue to rebound and fade after Character 1 disappears — clearly conveying instantaneous teleportation rather than running off-screen. Shot 03 | 00:3.5—00:6 | Two-Tone Realistic Slash 40mm medium shot from the hips up, from behind Character 3. The camera is positioned directly behind Character 3 at back height, close to Character 3, using a slightly upward low angle; Character 3 is positioned left-of-center in frame, facing right, eyes remaining closed throughout; Character 1 originally stood on the right side of the arena, with the attack direction running from right to left across the frame. The shooting direction is fixed — no orbiting, no crossing the axis; focus locks onto the outline of Character 3's back and the low airspace in front of them, with a medium depth of field keeping both subjects in focus while the audience stands and far structures remain blurred. Within the opening 0.3 seconds, Character 1 materializes instantly in the low airspace in front of Character 3 with intense directional motion blur, staying on the right side of the frame and only slightly higher than Character 3; Character 1 twists at the waist and back, swinging Character 2's blade — crackling with blue-white arcs — back behind them, the spine of the blade resting close to the back of Character 1's own neck, the body forming a compressed yet clearly readable power-charging stance. Immediately after, Character 1 releases force sequentially through waist, shoulder, elbow and wrist, slashing Character 2 violently from the upper right of the frame down to the lower left. Just as the blade is about to make contact with Character 3, the entire frame rapidly collapses into a stark blue-and-black duotone: Character 1 retains full color, while Character 3 and every visible character silhouette turn into pure black silhouettes, and the arena background compresses into a flat, dark-blue structural plane. Character 2 genuinely slashes Character 3 at the junction of the shoulder and neck on the side nearest Character 1, cutting diagonally across toward the opposite upper chest; at the instant of contact there is an extremely brief moment of resistance, with Character 3's clothing and body surface compressing along the direction of the blade, and the camera produces one extremely small impact tremor before immediately stabilizing; the force of the slash then carries through, and Character 3's upper body clearly shifts in the direction of the force. A large amount of black fluid sprays at high speed along the diagonal slash trajectory, breaking from a concentrated thick stream near the point of contact into realistic droplets of varying sizes, all remaining the current flat 2D black — never turning red, turning to smoke, energy particles, or abstract ink splashes; Character 1 remains in full original color throughout, and the arcs on Character 2's blade continue to illuminate Character 1's hand, the shadowed side of the face, and the edges of the black droplets.
✍️ Editor’s Notes

三个镜头对应三张参考图,用图一图二图三编号而不是角色名指代人物,这是多图输入场景的标准写法,方便模型对齐身份不串脸。最有意思的是镜头三那句「画面迅速坍缩为强烈蓝黑双色」,本质是把后期调色和转场特效直接写进生成指令里,还专门强调黑色液体不变成红色、烟雾、能量粒子——说明作者大概率试过好几版,模型一放开手就爱把黑液体画成鲜血或者魔法特效,这条是纠偏后的版本。
