ComfyUI全方位指南(4)LTX-2.5 ComfyUI文生视频尝鲜,显卡会OOM吗? 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ComfyUI全方位指南3LTX-2.3 ComfyUI文生视频制作与重点提示词如何用AI写作以及模型国内如何下载-CSDN博客文章浏览阅读147次。基于Tesla V100 16GB显卡实测开源多模态视频模型TX-2.3LTX-2.3文生视频流程。受限于显存仅能勉强运行FP8量化模型。启用--fast与fp16_accumulation优化后10秒视频生成耗时约264秒第二次显著快于首次的407秒。使用22B参数的FP8主模型、蒸馏LoRA及Gemma-3-12B文本编码器支持音画同步、高分辨率输出实现高效本地部署。https://blog.csdn.net/jiangkp/article/details/166796583?spm1001.2014.3001.5502其中一个模型下载强调一下两种方式哪个可以下就用哪个还没碰到同时都不行的四、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_enhance‌true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 teachers 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 teachers 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.结构设计说明开篇用吹哨子的手腕特写定住慢动作节奏从低动态的局部细节起步让LTX-2.5的时长预测器自动匹配更舒缓的慢动作时长不用手动硬设帧数选用环绕半周的运镜方式完美适配LTX-2.5擅长的空间类镜头生成特性比普通推拉更能体现操场场景的开阔感专门标注动作幅度控制在轻微到中等完全贴合LTX-2.5提示词技巧里的运动剂量控制原则从根源上避免新手常遇到的画面抖动、人物形变问题重复黄金时刻逆光的光影描述让LTX-2.5在环绕镜头的全程都能保持统一的逆光氛围不会出现中途光影跳变的情况 AI生成
