性价比高！LTX-Video图生视频方案

前言

文生视频，图生视频已经不新鲜了，但是开源的方案中，相对闭源的视频方案（keling、海螺、sora等）而言，没一个能打的！🥱，作为开源的拥护者，实属焦虑~。

也有不错的开源模型，如之前说的 Huanyuan，cogx 等。今天谈一个性价比高的开源方案 LTX。当然，只能谈性价比，因为效果也确实不是很稳定😂，但是小显存也可以跑起来。 Ltx 文生视频，按照官方的工作流直接部署就好，我这里主要讲图生视频的，因为我觉得这类场景更广，可以先生成满意的图，再进行视频创作。

效果

这是直出的效果，在剪映用了高清效果。

工作流

图片输入和处理

对图片进行处理，用了官方推荐的尺寸即可。

提示语处理

依旧让 llm 来，先发推图片，然后通过自定义镜头语言，主体动作，然 llm 进一步整理。

A woman with light skin, wearing a blue jacket and a black hat with a veil, looks down and to her right, then back up as she speaks; she has brown hair styled in an updo, light brown eyebrows, and is wearing a white collared shirt under her jacket; the camera remains stationary on her face as she speaks; the background is out of focus, but shows trees and people in period clothing; the scene is captured in real-life footage.
