LTX 2.5 万能提示词书写公式
为了获得最高的指令遵循度（Prompt Adherence）并避免画面冻结或抽搐，建议将提示词按时序发展组织为五大模块：
[运镜指令与镜头视角] + [主体外观与核心特征] + [时间线动作递进] + [光影氛围与环境材质] + [风格质感与色彩渲染]5 大核心要素拆解
| 要素 | 核心作用 | 实战推荐词汇（英文优先） |
|---|---|---|
| 1. 运镜与镜头 | 锁定视角、焦段与相机运动轨迹 | Slow dolly in, Low-angle tracking shot, 35mm anamorphic lens, FPV drone dive, Static wide establishing shot |
| 2. 主体外貌 | 精准刻画角色容貌、服饰、材质与配饰 | A cybernetic courier with iridescent visor, Elderly craftsman in a weathered leather apron, Translucent jellyfish |
| 3. 时序动作 | 描述随时间演进的连贯动作（严格按发生顺序） | First steps onto the rain-slicked balcony, pauses, then looks toward the horizon as lightning strikes |
| 4. 环境与光影 | 构建空间层次、天气、体积光与倒影 | Volumetric dusk sunlight filtering through fog, Bioluminescent cyan glow, Wet asphalt reflections, 8k HDR |
| 5. 风格质感 | 调控画面颗粒感、色调与艺术流派 | Kodak Vision3 500T 35mm film grain, Hyper-detailed skin textures, Makoto Shinkai anime aesthetic, Studio Ghibli palette |
标签堆砌 vs 导演长句：实测对比
LTX 2.5 的文本编码器专注于语法树分析与自然语意，标签堆叠容易导致注意力分散：
- ❌ 低效（标签堆砌）：
cyberpunk man, walking, neon lights, rainy street, 8k, cinematic, photorealistic, high quality, trending on artstation- 实测结果：相机运动生硬、人物面部漂移、霓虹招牌悬浮变形。
- ✅ 高效（导演级自然语言）：
A cinematic low-angle tracking shot follows a lone courier walking through a dense cyberpunk street at night. Neon blue and magenta signs reflect across wet puddles on the asphalt. Steam rises from sewer grates as futuristic hovercars zoom overhead. 35mm anamorphic lens, shallow depth of field, atmospheric volumetric haze.- 实测结果：平滑的前向跟拍运镜、自然的行进步伐、精准的水面光影倒影与浓厚的赛博朋克体积烟雾。
专业运镜指令词典（Camera Movement）
在提示词开头显式加入以下英文运镜指令，能精准控制 LTX 2.5 的时空动态：
| 运镜指令 | 镜头运动方式 | 最佳适用场景 |
|---|---|---|
Slow Dolly In | 慢速推镜头（向主体推进） | 角色登场、情绪升温、悬疑揭晓 |
Dolly Zoom (Vertigo Effect) | 眩晕变焦（推镜头+广角反拉） | 心理震撼、顿悟、惊悚反转瞬间 |
Low-Angle Tracking Shot | 低角度平移跟拍 | 动态行走、街头追逐、英雄角色仰拍 |
360-Degree Orbit | 360° 环绕运镜 | 产品展示、决战时刻、角色全景环顾 |
FPV Drone Flythrough | 第一人称穿越机高速俯冲穿梭 | 广袤自然峡谷、摩天大楼穿梭、极限运动 |
Crane / Jib Down | 摇臂自天空垂直下降 | 从大远景城市环境过渡到近距离人物对话 |
Macro Rack Focus | 微距焦点前后切换 | 雨滴、手表机械齿轮、微观生物延时 |

负向提示词（Negative Prompt）与参数最佳配比
核心参数推荐表
| 参数项 | 推荐数值区间 | 调节经验与注意事项 |
|---|---|---|
| CFG / Guidance Scale | 3.0 - 4.2 | 决定模型遵循 Prompt 的严格程度。超过 5.0 容易导致画面发焦或过曝。 |
| Diffusion Steps (步数) | 25 - 35（标准 DiT）/ 8 - 12（蒸馏快排） | 兼顾生成效率与细节分辨率的最佳平衡点。 |
| Denoise (去噪强度) | 0.45 - 0.65（用于 I2V/V2V） | 0.45 保护原图/原视频主体；0.65 允许大幅度跨维度风格迁移。 |
通用负向提示词模板（Negative Prompt）
在生成高复杂度人物或高动态场景时，建议使用以下经过验证的通用负词：
blurry, low quality, distorted anatomy, warped faces, flickering background, unnatural jitter, sudden popping geometry, overexposed, oversaturated colors, static freeze frame, watermarks, text overlays常见问题与排坑指南
1. 为什么用标签堆叠（Tags）会效果很差？
LTX 2.5 采用 Gemma 4 12B 语言大模型 作为文本编码器。它依靠主谓宾语境、时间连词（first, then, while）与介词短语来定位空间坐标。如果只是把单词用逗号隔开，时间注意力机制无法理解事件的发生顺序。
2. 如何保证多镜头切换（Multi-Shot）时主角不变样？
在 Prompt 中对主角的核心特征进行明确锚定（例如：woman in a bright yellow raincoat with short black bob hair），并在提示词末尾加上约束短语：Preserve character facial structure, outfit, lighting direction, and aesthetic across all cuts.
3. 可以直接上传图片来生成动态视频吗？
可以！使用 LTX 2.5 图生视频工具（Image to Video）。此时提示词仅需描述动态变化（如：Gentle camera push-in, wind blowing hair softly, warm sunlight drifting across her face），视觉主体将完全沿用图片本身。
