一、说明
接着上篇，我们今天想尝尝鲜，看看我的Tesla V100 16G能不能跑动LTX-2.5
硬件配置
cup型号： E5 2673V3
主板：X99 P8D3 3 显卡插槽，不过空间太紧凑，只能两张
内存大小： 2*4g + 2*8g = 24g ddr3
显卡型号：算力卡 NVIDIA V100 16G + 亮机卡 HD 7570
二、取模板
三、下载模型
上一篇我们详细介绍了如何下载模型，这里就不讲了
四、运行
参数改改，尺寸设置为0.2,试试水，免得ooc了
等着就是了
INFO Prompt executed in 97.98 seconds
速度和2.3比要快
我们修改下参数：
prompt_enhance：true，开启提示词增强功能，自动优化输入的文本描述，提升生成内容的匹配度，这是生成结果每次都高度稳定的核心开关之一
再试试
INFO Prompt executed in 321.01 seconds
还可以按，比2.3好画质也还可以
五、提示词
我在百度文心助手上的提问
请按照LTX-2.5的最优提示词结构设计，给我写一个30岁的老师在课堂上讲课的场景，并且按照LTX-2.5的最优提示词结构详细说明为什么这么写，另外给出中英文对照，给出3个版本，提醒一下，老师是地道的东方大国的中国女人，3个版本分别为，老师讲课时，老师听同学回答问题时，还有体育老师上体育课时
LTX-2.5 本次提示词通用设计逻辑
完全贴合LTX-2.5的核心优势：长文本细节不丢失、跨镜头动态连贯、光影与人物特征全程锁定，严格遵循「局部特写锚定→镜头运动展开→全景氛围铺底→细节质感强化→画质约束收束」的五层最优结构，既发挥Gemma 4 12B长文本编码器的细节承载能力，又避免传统提示词信息零散导致的人物漂移、画面畸变问题。
版本一：语文老师站在课堂讲台上讲课
中文提示词近景特写，30岁地道中国女语文老师的侧脸，黑亮长发在脑后低扎成马尾，细框眼镜滑到鼻梁半中间，她指尖捏着半支白色粉笔，正俯身指着黑板上的毛笔字，嘴唇微微张开，正念出古诗的最后一句，粉笔灰在窗边斜射进来的午后阳光里轻轻浮动。镜头缓慢向后拉远，露出她身上洗得柔软的浅蓝棉麻衬衫，讲台边堆着半摞批改完的作文本，前排课桌上摊开的语文课本上，用荧光笔划出的诗句标记清晰可见。镜头继续拉远，完整的江南中学教室全景铺开，木质课桌椅整齐排列，后排墙上贴着半旧的书法作品，几个学生托着下巴正望向讲台，窗外的香樟树叶被风刮得轻轻晃动。细节质感：真实东方人皮肤纹理，眼角极淡的笑纹，粉笔表面的细微磨损，纸张边缘的自然泛黄，无AI畸变，无多余手指。核心约束：全程保持老师的五官、发型、服装完全一致，光影从始至终是午后柔和的漫射日光，画面自然不刻意。画质标签：4K，电影级自然光，24fps，流畅镜头运动，高细节，无运动伪影。
English PromptClose-up shot of a 30-year-old authentic Chinese female Chinese language teacher's profile, black shiny long hair tied in a low ponytail at the back of her head, thin-rimmed glasses slipping halfway down her nose bridge, her fingertips pinching half a white chalk, leaning over and pointing at the calligraphy on the blackboard, lips slightly parted as she speaks the last line of an ancient poem, chalk dust floating gently in the afternoon sunlight slanting through the window. The camera slowly pulls back, revealing her soft washed light blue linen shirt, half a stack of corrected exercise books piled by the podium, the fluorescent highlighted poem marks clearly visible on the Chinese textbook spread out on the front desk. The camera continues pulling back, the full panorama of a Jiangnan middle school classroom unfolds, wooden desks and chairs arranged neatly, half-old calligraphy works pasted on the back wall, several students resting their chins looking towards the podium, camphor tree leaves outside the window shaking gently in the wind. Texture details: real oriental skin texture, extremely faint smile lines at the corners of the eyes, slight wear on the chalk surface, natural yellowing at the edges of the paper, no AI distortion, no extra fingers. Core constraint: keep the teacher's facial features, hairstyle, and clothing completely consistent throughout the shot, the light remains soft afternoon diffuse daylight from start to finish, the scene looks natural and unforced. Quality tags: 4K, cinematic natural lighting, 24fps, smooth camera movement, high detail, no motion artifacts.
结构设计说明
-
开篇直接用侧脸+捏粉笔的局部特写锚定人物核心身份，第一时间把观众带入课堂场景，符合LTX-2.5优先抓取主体细节的特性
-
镜头后拉的动态过程中，逐步带出讲台、课本、教室全景，让LTX-2.5的运动生成逻辑有明确的递进路径，不会出现画面跳变
-
反复重复"中国女老师""浅蓝棉麻衬衫""午后日光"等关键特征词，保证跨帧人物一致性，完全规避传统AI视频常见的人脸漂移问题
-
细节部分专门指定真实东方人皮肤纹理，精准还原中国女性的自然神态，避免生成欧美化的畸变五官
上图中的参数已经添加了我们版本一代提示词
版本二：体育老师在室外操场带学生上体育课
中文提示词慢动作特写，30岁中国女体育老师的手腕，她正抬手吹响银色的哨子，哨子的挂绳是亮眼的橙色，额前的碎发被操场的风直接吹起来，运动服外套的拉链拉到胸口，露出里面印着学校名字的白色速干T恤。镜头缓慢环绕她半周，露出她脚边放着的橙色接力棒，不远处几个学生正弯腰做起跑预备动作，塑胶跑道上的白色分道线被晒得微微发旧。镜头继续环绕拉开，整个操场的全景完全展开，远处的篮球架立在香樟树下，跑道边的草坪上散落着几个彩色的标志锥，风把操场边的五星红旗吹得轻轻扬起，远处教学楼的窗户反射着下午的金色阳光。细节质感：运动后皮肤表面的薄汗，哨子金属表面的细微划痕，塑胶跑道颗粒的粗糙质感，布料被风吹动的自然褶皱，无肢体畸变。核心约束：全程人物的运动状态自然舒展，所有动作幅度控制在轻微到中等，避免画面剧烈抖动，光影全程是下午四点的黄金时刻逆光。画质标签：4K，运动写实风格，24fps，流畅环绕运镜，高动态范围，无运动模糊过度。
English PromptSlow-motion close-up of the wrist of a 30-year-old Chinese female PE teacher, she raises her hand to blow the silver whistle, the lanyard of the whistle is bright orange, the broken bangs on her forehead are blown up directly by the playground wind, the zipper of her tracksuit jacket is pulled to the chest, revealing the white quick-dry T-shirt printed with the school name inside. The camera slowly orbits half a circle around her, revealing the orange relay baton placed by her feet, several students not far away bending over to get into the starting position, the white lane lines on the plastic track are slightly worn from the sun. The orbit continues to pull back, the full panorama of the entire playground unfolds completely, the distant basketball hoop stands under the camphor tree, several colorful marker cones scattered on the lawn by the track, the five-star red flag by the playground flutters gently in the wind, the windows of the distant teaching building reflect the golden afternoon sunlight. Texture details: thin sweat on the skin surface after exercise, tiny scratches on the metal surface of the whistle, rough texture of the plastic track particles, natural wrinkles of the fabric blown by the wind, no limb deformities. Core constraint: all characters' movements are natural and relaxed throughout, all movement amplitudes are controlled between mild to medium to avoid severe camera shake, the lighting remains golden hour backlight at 4 PM the entire time. Quality tags: 4K, sports realistic style, 24fps, smooth orbiting shot, high dynamic range, no excessive motion blur.
