使用Wan2.2最好搭配加速lora使用，能够加快视频生成速度，由于网络上有太多的加速lora模型，这里就不一一列举，只列出在本文示例中使用的加速lora，Wan21_T2V_14B_lightx2v_cfg_step_distill_lora_rank32.safetensors
1、提示词
官方在发布模型的同时，将自己的知识库交给chatgpt制作了一个Wan Cinematic Video Prompt Generator，大家通过这个地址与他进行交流沟通，让chatgpt输出跟工作流相关的提示词。
2、视频生成的参数建议
在生成视频的时候有两次采样，第一次使用高噪声专家模型采样生成视频的整体结构，第二次则使用低噪声专家控制优化视频的细节。
📺 文本转视频参数建议（T2V）
| 参数 | 建议值 |
|---|---|
| CFG | 根据Create CFG Schedule Float List节点以及step步数动态调整 |
| Shift | 1.5效果最佳 低值趋于真实静态，高值（3-9）更风格化，动作幅度大的场景 |
| Scheduler | dmp++_sde/beta 最佳 |
如下，按照官方设置，step为6，则第一步的cfg为2，后面5步的cfg为2
🖼️ 图像转视频参数建议（I2V）
| 参数 | 建议值 |
|---|---|
| CFG | 1（必须） |
| Shift | 8 效果最佳 |
| Scheduler | dmp++_sde/beta 最佳 |
| 建议帧数/FPS | 121 帧 @ 24 FPS |
⚙️ 技术建议
- ✅ 可在 6 步运行，但是这6步分别被拆分为了高噪声采样3步，低噪声采样3步
- 🔧 使用 Kaji WAN Wrapper
- 🧪 原生 WAN 工作流同样可用，但渲染速度更慢
- ❗ 不要重复加载 CausVid / AccVideo / MPS LoRA（已内置）
- 🎨 可添加其他风格化 LoRA 调整外观
🧠 渲染参数示例
- 分辨率：1280×720
- 帧数：121
- 使用硬件：RTX 4090 → 每个视频约9分钟
- 显存不足时建议启用 block swapping（建议 30 blocks 起）
- 使用 SageAttn 可提速约 30%（需 Wrapper 支持）
- 不建议启用 teacache

The camera remains fixed on a single spot, focusing on a puddle on the road. The still water reflects the sky and surrounding environment. As time passes, a bicycle rider rides through the frame, their reflection appearing on the water's surface. Moments later, a car passes by, sending a small ripple through the puddle, followed by a dog running along the road. The dog's reflection briefly distorts the water as it moves, and then a cat walks by, its reflection lingering in the puddle for a few seconds. The scene captures the tranquil and rhythmic flow of life through the water’s reflection.相机固定在一个地方，聚焦在路上的一个水坑上。平静的水面反射着天空和周围的环境。随着时间的流逝，一个骑自行车的人穿过画框，他们的倒影出现在水面上。过了一会儿，一辆汽车开了过去，在水坑里激起了一个小涟漪，后面跟着一条狗沿着路跑。狗的倒影在移动时短暂地扭曲了水，然后一只猫走过，它的倒影在水坑里停留了几秒钟。这个场景通过水的反射捕捉到了宁静而有节奏的生命流动。
A close-up of a young couple in a car, laughing and talking to each other. The sunlight filters through the windows, casting soft, golden bokeh across their faces. The camera slowly dollies out as their laughter fades and their expressions shift. They both glance out the window, their faces turning thoughtful and distant. The mood shifts from joy to quiet introspection as the background slowly blurs, leaving a sense of uncertainty and unspoken thoughts.一对年轻夫妇在车里谈笑的特写镜头。阳光透过窗户照进来，在他们的脸上投下柔和的金色散景。随着他们的笑声逐渐消失，他们的表情也在变化，镜头慢慢变亮。两人都朝窗外看了一眼，脸上的表情变得若有所思而又疏远。随着背景逐渐模糊，情绪从喜悦转变为安静的内省，留下一种不确定感和无法言说的想法。
A close-up of a man sitting silently at the roadside during golden hour, warm sunlight casting soft shadows across his face. His expression is distant, eyes filled with unshed tears. The camera lingers as his lips tremble, then he suddenly breaks down, burying his face in his hands. The camera begins to slowly dolly backward, revealing more of the empty road and the quiet, wind-blown trees around him. The scene is intimate, melancholic, and emotionally raw.一个男人在黄金时段静静地坐在路边，温暖的阳光在他脸上投下柔和的阴影。他的表情是冷漠的，眼里充满了未流出的泪水。镜头停留在他嘴唇颤抖的时候，然后他突然崩溃了，用手捂住脸。摄像机开始慢慢地向后移动，更多地展示了空旷的道路和他周围安静的、被风吹动的树木。这个场景亲密、忧郁、情感原始。
A high-speed car chase through a deserted highway, with the sun setting behind distant mountains. The camera follows from a low, dynamic angle, tracking the cars as they race past with tires screeching and engines roaring. Dust kicks up from the road as the camera shifts rapidly between wide shots and close-ups, showing the drivers’ focused expressions. The air is filled with the sound of the engines, and the mood is intense, full of adrenaline and danger.一辆高速行驶的汽车在无人的高速公路上追逐，太阳落在远处的山后。摄像机从一个低的动态角度跟随，跟踪汽车疾驰而过，轮胎发出刺耳的声音，引擎轰鸣。随着镜头在广角镜头和特写镜头之间快速切换，道路上扬起了灰尘，显示出司机专注的表情。空气中充满了引擎的声音，气氛紧张，充满了肾上腺素和危险。
The camera opens with a wide-angle shot of a detailed fantasy landscape, where towering castles sit atop rocky cliffs. The lighting is soft and cinematic, with the sun casting long shadows across the meticulously designed stone paths and waterfalls. As the camera dolly in, you can see the intricate textures on the buildings, the bricks, and wooden doors. The glimmering water in the distance reflects the surroundings, and the camera slowly pans over lush forests and glowing magical creatures wandering in the background.镜头以广角镜头打开，展现了一幅奇幻风景的细节，高耸的城堡坐落在岩石悬崖上。灯光柔和而电影化，阳光在精心设计的石头小径和瀑布上投下长长的阴影。随着摄像机的移动，你可以看到建筑物、砖块和木门上复杂的纹理。远处波光粼粼的水面反射出周围的环境，镜头慢慢地移向茂密的森林和背景中徘徊的发光的神奇生物。
A time-lapse of a bustling city square during the day, starting with a wide shot of the empty plaza. As time progresses, people begin to fill the space, walking in and out, while clouds float overhead and the light shifts from morning to afternoon. The camera captures the movement of the crowd and changing light in smooth intervals, emphasizing the ebb and flow of life within the frame. The scene eventually transitions into evening as the square empties again.白天一个熙熙攘攘的城市广场的延时拍摄，从一个空荡荡的广场的广角镜头开始。随着时间的推移，人们开始填满空间，进进出出，而云层漂浮在头顶上，光线从早上转移到下午。相机捕捉到人群的运动和平滑间隔的光线变化，强调画面内生命的潮起潮落。随着广场再次清空，场景最终过渡到傍晚。

The robot gestures with its hands, as if emphasizing its words, while the city lights in the background flicker, adding tension to the moment.场景以黑白开始，一个高大的，细节细致的机器人站在昏暗的城市街道上，类似于你提供的图像。机器人慢慢地抬起它巨大的手臂，指向站在它面前的人。当机器人张开嘴巴时，镜头聚焦在它的脸上，低沉的机械声音开始说话。这个人全神贯注地听着，他们的表情混杂着好奇和谨慎。机器人用手做手势，好像在强调自己的话，而背景中的城市灯光闪烁，给这一刻增加了紧张感。
The video begins with a close-up shot of a glowing, red-hot iron ball resting on top of a large, solid ice block. As the ball makes contact with the ice, steam rises as the intense heat begins to melt the ice, creating a sizzling sound. The water from the melting ice starts to bubble and rapidly increase in temperature, turning into hot steam and shimmering around the ball. As the ice continues to melt, the red glow of the ball slowly fades, with the iron ball gradually cooling down and the molten water trickling down the sides of the ice block.视频的开头是一个特写镜头，一个炽热的红铁球放在一个巨大的固体冰块上。当球与冰接触时，随着高温开始融化冰，蒸汽上升，发出嘶嘶声。融化的冰中的水开始冒泡，温度迅速升高，变成热蒸汽，在球周围闪闪发光。随着冰继续融化，铁球的红光慢慢消失，铁球逐渐冷却，融化的水沿着冰块的两侧滴落。
A warrior dressed in ancient armor with a monkey-like face and a red scarf walks slowly toward the camera through a dusty, sunlit village ruin. The camera uses a low-angle dolly-in, emphasizing his intense gaze and calm yet imposing demeanor. As he approaches, he lifts his golden staff and smoothly swings it behind his head, resting it across his shoulders. Both hands rise to grip the staff, forming a relaxed yet commanding stance. The golden-hour lighting casts warm shadows across the sandstone walls, enhancing the mythic and heroic mood of the scene.一名战士穿着古老的盔甲，长着猴子般的脸，戴着红领巾，穿过一片尘土飞扬、阳光普照的村庄废墟，慢慢走向镜头。镜头采用了低角度拍摄，强调了他强烈的凝视和冷静而又威严的举止。当他走近时，他举起他的金杖，在他的头后平稳地摆动，放在他的肩膀上。双手举起握杖，摆出轻松而威严的姿态。黄金时段的灯光在砂岩墙上投下温暖的阴影，增强了现场的神话和英雄情绪。
