重来一次，使用Minimax H3 生成一段40s动画 （升级第三版sage att 优化）
-
前文：看回之前我使用ltx2.3 的动画，
https://lcz.me/topic/560/菜鸟先使用ltx2.3-试一试2分钟动画现在把所有素材丢进Minimax H3 看看效果，
照旧使用官方网站的模型，workflow, 我自己再加入Rtx Upscale 4k
使用昨天的才上载的模型，
minimax_h3_fl2va_pruned_fp8_scaled.safetensorstext encoder使用blackwell 版本专用
qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors其他照旧
minimax_h3_audio_vae_fp32.safetensors
minimax_h3_video_vae_fp16.safetensors
提示词：
镜头 1 (000 - 05) —— 远景：俯冲肃杀家庭.txt
我没有加入太多动作设计的提示，我相信如果有详细的动作提示，他会出色得多
现在minimax h3, 没有加片头片尾，也没有加字幕，也没有剪辑，纯粹来自minimax h3
之前ltx2.3, 有加片头片尾，加字幕，加剪辑
之前想着把提示词分开8段，然后发觉倒不如干脆一次过把8段提示词全部放进promt里面
40秒的动画，总共花了1个小时半
照样占满所有32gb vram, 附加一点dram，留意他的所有vae 都是full load, lowram patch = 0, 意思是极少用到dram，估计是因为我设定40s, 所以他每走一个step 都是把40s 拿去处理，261s/it 总共20 step
出来4k 画面，单档 117MB

分镜一致性和无缝拼接是两件事，分开答：
一致性：多镜头生成时，每个镜头都要喂同一张"角色锚点图"作为首帧参考——H3 的 text encoder（qwen3vl）会读取参考帧的构图、人物、光影，所以只要锚点图不变、提示词里人物描述保持一致，角色和场景风格就不会漂。想要更稳可以加 IPAdapter 或角色 LoRA，但 H3 本身对首帧参考的遵循度已经很高，锚点图选准就够了。你问"是不是每段都从新图生成"——对，多镜头工作流通常就是每段独立文生/图生，靠锚点图统一。
无缝拼接：首尾帧硬接必然断层，因为上一段结尾的运动状态、光影、色彩延续不到下一段开头。三个实用解法：
- 重叠+交叉淡化：两段之间多生成 10-15 帧重叠区，接缝处做 5-10 帧线性交叉淡化（ComfyUI 里 VFX/过渡节点或视频后期都行），断层肉眼基本消失。
- 接续式生成：下一段的首帧直接用上一段的最后一帧（而不是原始锚点图），相当于"续写"而不是"重开"，运动连贯性最好；代价是如果上段结尾画面糊，会一路糊下去。
- 色彩匹配收尾：断层很多时候不是动作问题，是亮度/色温跳变。接缝前对后段做一次 color match（或简单 LUT 校正），比调生成参数更省事。
"多宫格分镜"是另一条路：把多个镜头放进同一张网格图一次生成，全局光照和色调天然统一，但单镜头分辨率会被摊薄，40 秒这种长片分段生成 + 交叉淡化更实用。我自己做多段视频就是"锚点图保一致 + 重叠交叉淡化接缝"，断层问题基本能压住。

请问这个工作流是每一段生成的视频都是从新的图片生成的吗？场景角色一致性是怎么解决的？
@Quanta-Magic 这一次我是一次过生成，没有分段，因为我已经写好每一个段落的剧本了
-
多宫格分镜吗？我比较好奇怎么生成可以完美拼接的视频，我做的工具是用首尾帧，但是每段视频之间有明显断层
@Quanta-Magic
我原本就计划使用分段生成，然后并接。。。。后来懒惰，干脆一次过把剧本放进去，让minimax完成全部东西

升级第三版sage att 优化
添加了minimax 加速，处理时间从 1.5小时，减少至58分钟
添加了动作设计，特效，全段一次过40秒处理。。
动画中间有重复画面，没有时间去检查，就纯粹跟回之前的处理步骤
提示词如下：
镜头 1 (0:00 - 0:5) —— 远景：俯冲肃杀家庭
节奏与特效：慢速俯冲，在中心点因内力爆发产生气浪涟漪。Prompt：Cinematic drone shot, high angle slowly gliding down to a grand ancient Tang dynasty courtyard, suddenly accelerating into a violent dive. Weathered black tile roofs and pristine white walls. In the center sits a massive ancient bronze cauldron on a stone platform. A sudden burst of invisible inner qi energy ripples outward, shattering surrounding tiles and causing crimson maple leaves to swirl furiously. Below, terrified red koi fish scatter in panic under pond water. Highly detailed 3D anime style, 8k.镜头 2 (0:5 - 0:10) —— 中景：将军低空入局
节奏与招式：长枪拖地，蓄力突刺的慢动作定格。Prompt：Low-angle tracking shot. A Tang dynasty general strides aggressively, dragging a long steel spear that scrapes against the stone floor creating friction sparks. The fierce autumn wind blows his red cape violently. The camera abruptly switches to ultra slow-motion as he thrusts the spear forward fiercely, the spearhead spiraling with a drilling wind vortex effect, blowing swept-up maple leaves into dust. High-energy camera movement, donghua style.镜头 3 (0:10 - 0:15) —— 特写：暗器旋转破空
节奏与特效：暗器缠绕黑色气劲，击碎长枪气流。Prompt：High-speed bullet-time tracking shot. A sharp silver dagger weapon, enveloped in an eerie black smoky qi aura, spins furiously through the air. The camera moves at extreme high speed, tracking the weapon as it slices perfectly through the general's spear wind vortex, creating a sharp glass-shattering shockwave effect in mid-air. Motion blur on edges, crisp reflections, photorealistic anime style.镜头 4 (0:15 - 0:20) —— 近景：挥剑爆火花与甩镜头
节奏与招式：长枪横扫格挡，刺客双剑乱舞。Prompt：Rapid whip-pan shot. The general swings his long spear in a circular motion, executing a powerful block that creates a golden energy shield aura. Sparks and electrical arcs fly as he parries a flurry of strikes from a black-clad assassin wielding dual spinning swords. The camera pans violently, locking onto the assassin flipping backwards mid-air, leaving twin trails of white sword light. Dynamic martial arts action.镜头 5 (0:20 - 0:25) —— 中景：轻功飞天垂直升空
节奏与招式：轻功御气，空中长枪对双剑的定格交锋。Prompt：Dynamic vertical rising shot. The two masters leap high into the sky. The camera transitions into slow-motion as they exchange intense spear thrusts and dual-sword slashes mid-air, their weapons colliding to release shockwaves that push away the clouds. They step on glowing qi-infused maple leaves to gain altitude, then instantly accelerate upward like rockets into the storm. Stunning cinematic martial arts composition.镜头 6 (0:25 - 0:30) —— 屋顶半空：360度极速激战
节奏与招式：360度环绕极速残影，长枪横扫对双剑十字格挡。Prompt：Fast 360-degree orbital sweep shot in mid-air. Two warriors clash fiercely above a sweeping black tiled roof. The general unleashes a devastating 360-degree spear sweep, emitting a crescent golden energy shockwave. The assassin counters by forming a defensive X-shape with dual swords, creating a brilliant explosion of sparks and dark purple qi. Motion blur shadow effects, rapid weapon swinging, the camera rotates at high speed around the explosive combatants. High-energy action, beautiful donghua art style.镜头 7 (0:30 - 0:35) —— 微距特写：滴血入水
节奏与特效：极速微距突变超慢动作，内力顺着血滴消散。Prompt：Macro close-up shot. The camera switches to ultra slow-motion bullet-time. A single shiny red blood drop, infused with faint dissolving energy particles, slides down from a sharp steel sword tip and falls toward a calm water surface. The camera drops rapidly in perfect sync with the blood. The moment the drop hits the pond, a powerful sonic wave ripple blasts outward, clearing the mist and scattering green lily pads. High frame rate aesthetic, crisp textures, moody dramatic lighting.镜头 8 (0:35 - 0:40) —— 远景：飞檐走壁与拉远拉高
节奏与招式：刺客轻功踏空残影，镜头垂直冲向云霄。Prompt：Fast pull-out aerial crane shot, rising rapidly into the storm clouds. Below, the black-clad assassin leaps across continuous traditional roofs with extreme agility, leaving faint afterimages before vanishing into the misty distant mountains. On the white stone bridge, the general uses his shattered long spear to prop himself up, kneeling heavily as his glowing armor dims. The courtyard returns to a chilling peace, autumn wind slows down, majestic martial arts ending scene, 8k. -
