minimax H3 做大片

现在AI视频这么火，也想尝试一下，但是seedance的价格不菲，不过minimax H3开源了，免费本地也能玩，得好好学学。
视频发在x上了，点击观看。

虽然是免费的，全能参考，图片、视频样样不缺。还是很厉害的，生成一个灾难大片桥段试试——哥斯拉破坏城市。关键是测试可控性。这个minimax确实强。这个视频首帧参考图是用gemini生成的。镜头控制动画用blender制作，3d模型是免费的trellis2模型生成。最后用minimax h3的全能参考合成。

这个是提示词：
subject_definitions:
<Subject 1> is the colossal reptilian titan (Godzilla) in <Picture 1>, featuring rugged charcoal scaly armored hide, glowing fiery dorsal plates, muscular claws, and an imposing stance, whose roaring, head-tracking, and turning movement follow <Video 1>.
<Subject 2> is the military gunship/transport helicopter in <Picture 1>, finished in dark olive-drab plating with tactical markings, rotating main rotors, and chin-mounted optical sensors, whose forward flight toward the titan and subsequent high-speed 360-degree circling flight around Godzilla follow <Video 1>.
<Subject 3> is the storm-battered, war-torn metropolitan city street in <Picture 1>, featuring shattered skyscrapers, burning storefronts with neon signs, crushed civilian cars, downed powerlines, concrete rubble, and searching spotlights piercing through torrential rain.
<Picture 1> is the exact first frame of [Shot 1] at 0.00 seconds, defining the opening composition, photorealistic disaster atmosphere, rainy illumination, and initial spatial coordinates of <Subject 1>, <Subject 2>, and <Subject 3>.

<Video 1> is the 10-second reference video (0001-0240.mkv) providing the continuous camera tracking motion following <Subject 2> as it flies forward toward <Subject 1> and performs a complete circular orbit around the colossal creature.

summary:
[keyframe completion + reference generation] The 10-second target video opens precisely from <Picture 1> at 0.00 seconds as its first frame in [Shot 1]. Following the camera tracking path and aerial flight choreography of <Video 1>, the camera closely follows behind the military helicopter <Subject 2> as it charges forward toward the colossal titan <Subject 1> (Godzilla) over the burning streets <Subject 3>, banks steeply, and executes a daring 360-degree tactical flight circling completely around the roaring monster.

retention_analysis:
<Subject 1> (appears in [Shot 1]): fully_preserved - the massive creature's charcoal scale textures, fiery dorsal fins, and towering presence from <Picture 1> are retained, while its head-tracking, torso pivot, and roar follow <Video 1>.
<Subject 2> (appears in [Shot 1]): fully_preserved - the helicopter's olive-drab fuselage, spinning rotor wash, and tactical markings from <Picture 1> are maintained as its forward flight and 360-degree circling orbit around the monster follow <Video 1>.
<Subject 3> (appears in [Shot 1]): fully_preserved - the torrential rain, burning street rubble, crumbling skyscrapers, and volumetric searchlights from <Picture 1> remain consistent throughout the continuous shot.
<Picture 1> ([Shot 1] first frame): fully_preserved - <Picture 1> serves as the definitive opening frame at 0.00 seconds, locking composition, lighting, and initial subject placement.

<Video 1> (flight choreography and tracking camera): fully_preserved - the 10-second camera-following-helicopter trajectory, the aircraft's forward approach and full circular orbit around Godzilla, and the synchronized timing are completely referenced.

detailed_description:
The target video is crafted in an ultra-photorealistic, cinematic Hollywood blockbuster disaster-action aesthetic, featuring gritty desaturated charcoal and steel-blue tones, atmospheric volumetric downpour, and intense orange firelight contrast.
[Shot 1] The shot begins directly from <Picture 1> at 0.00 seconds in a dynamic third-person chase perspective. In the immediate right-foreground, <Subject 2>, the military gunship helicopter, hovers briefly above the asphalt littered with crushed police cars and burning debris before tilting its nose downward and accelerating forward along the street canyon. Its spinning rotors slice through heavy rain, flinging spiral vapor trails and fanning glowing embers across the pavement. Ahead in the rainy distance, <Subject 1>, the colossal Godzilla, looms between crumbling skyscrapers in <Subject 3>, its jagged dorsal plates pulsing with radioactive amber fire. As dictated by <Video 1>, the camera dynamically follows behind and alongside <Subject 2>, tracking its forward charge directly toward <Subject 1>. At 00:02.500, closing within proximity of the monster's chest, <Subject 2> banks sharply into a high-speed flanking turn to evade the titan. <Subject 1> rears its head back, tracks the approaching aircraft with glowing fierce eyes, and unleashes a deafening, earth-shaking roar; the concussive soundwave visibly ripples through sheets of falling rain and blows shattered window glass off surrounding facades. From 00:04.500 to 00:07.500, strictly following the aerial path in <Video 1>, <Subject 2> executes a tight, sweeping 360-degree tactical arc around <Subject 1>, flying past its right flank and circling behind its massive spiky back. The camera stays locked on the helicopter's tail and side, weaving through rising columns of black smoke and rain mist as the glowing dorsal ridges of Godzilla pass by in the midground like a burning mountain range. <Subject 1> twists its colossal torso and turns its head, swiping a massive claw through the air to swat at the agile aircraft. From 00:07.500 to 00:10.000, <Subject 2> completes its full orbit around the monster and sweeps out past the opposite shoulder toward open airspace, banking hard as searchlights and flashing red anti-collision beacons glint against its rain-drenched olive-drab fuselage, while Godzilla roars once more into the stormy sky amidst exploding towers and raging fires.

overall_soundscape:
Dominant close-range turbine whine and heavy rhythmic blade chop of the military helicopter's main rotors, paired with intense drumming of torrential rain against the metal fuselage. Surrounding sounds include booming concrete collapses, howling wind, cracking electrical transformers, and the colossal, reverberating metallic-guttural roar of Godzilla echoing across the city.

non_diegetic_music:
A driving, high-octane cinematic action-disaster score with urgent staccato strings, aggressive brass ostinatos, and thunderous taiko and orchestral percussion impacts that surge during the helicopter's high-speed orbit and the titan's roar, evoking extreme tactical tension and cinematic scale.
