AniCrafter: Customizing Realistic Human-Centric Animation via Avatar-Background Conditioning in Video Diffusion Models, you can try this methods when use ComfyUI.

Update

0715 修复无法重复推理的bug，修复高斯np文件加载device错误，修复输入图片自动裁切错误,example 新增测试用的华仔及其np文件和美少女跳舞内容；
支持自定义视频的推理，支持预处理视频（mask，背景内绘及smplx剪辑）和json文件的以及gaussian.pth的复用（首次生成需要选择none）；为避免人脸失真，推理尺寸越大越好。等下个周末再修复一些bug吧。
need another weekend to fix bugs

1. Installation

In the ./ComfyUI /custom_node directory, run the following:

git clone https://github.com/smthemex/ComfyUI_AniCrafter.git

2. Requirements

pip install -r requirements.txt

and


pip install flash-attn --no-build-isolation
pip install tb-nightly
pip install git+https://github.com/XPixelGroup/BasicSR
pip install git+https://github.com/facebookresearch/pytorch3d.git
pip install git+https://github.com/hitsz-zuoqi/sam2/
pip install git+https://github.com/ashawkey/diff-gaussian-rasterization/
pip install git+https://github.com/camenduru/simple-knn/

If python version >3.10,need modify 'chumpy' packeage :

'...site-packages\chumpy\ch.py' ,line 1203 ,change ' inspect.getargspec' to 'inspect.getfullargspec'
'...site-packages\chumpy__init__.py' ,line 11,change 'from numpy import bool, int, float, complex, object, unicode, str, nan, inf 'to

from numpy import complex_, object_, nan, inf
import builtins
bool_ = builtins.bool
int_ = builtins.int
float_ = builtins.float
str_ = builtins.str
