# 通义万相2.1-1.3B-LoRA-速度控制-v1

## 模型介绍

本 LoRA 模型是基于模型[通义万相2.1-1.3B](https://www.modelscope.cn/models/Wan-AI/Wan2.1-T2V-1.3B)和框架 [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio) 训练的LoRA。本模型可以通过调整 LoRA alpha 参数控制视频的速度。

* **LoRA alpha > 0**: 使用触发词 low speed，速度变慢，画质增强
* **LoRA alpha < 0**: 使用触发词 high speed，速度变快，画质降低

## 模型效果

提示词：纪实摄影风格画面，一只活泼的白色小狗在绿茵茵的草地上迅速奔跑。小狗毛色雪白，两只耳朵立起，神情专注而欢快。阳光洒在它身上，使得毛发看上去格外柔软而闪亮。背景是一片开阔的草地，偶尔点缀着几朵野花，远处隐约可见蓝天和几片白云。透视感鲜明，捕捉小狗奔跑时的动感和四周草地的生机。中景侧面移动视角。

负面提示词：色调艳丽，过曝，静态，细节模糊不清，字幕，风格，作品，画作，画面，静止，整体发灰，最差质量，低质量，JPEG压缩残留，丑陋的，残缺的，多余的手指，画得不好的手部，画得不好的脸部，畸形的，毁容的，形态畸形的肢体，手指融合，静止不动的画面，杂乱的背景，三条腿，背景人很多，倒着走

LoRA alpha = 0.7
