ComfyUI I2VGenXL

Unofficial implementation of I2VGenXL for ComfyUI

I2V_00002.1.mp4

项目介绍 | Info

  • I2VGenXL的非官方实现,实测下来是目前 动效自然程度光影 最好的 高清 视频模型(幅度没有SVD1.1大,但是综合效果比 SVD1.1 强)

  • I2VGenXL 特点:

    • 与 SVD 不同,I2VGenXL 可以通过输入正负提示词来完成更好的生成
    • 分辨率:1280*704
    • 生成帧数:16帧
    • 速度:A100约97s(比 SVD1.1 慢 20%)
  • 版本:V1.0

安装 | Install

  • 推荐使用管理器 ComfyUI Manager 安装(On the Way)

  • 手动安装:

    1. cd custom_nodes
    2. git clone https://github.com/ZHO-ZHO-ZHO/ComfyUI-I2VGenXL.git
    3. cd custom_nodes/ComfyUI-I2VGenXL
    4. pip install -r requirements.txt
    5. 重启 ComfyUI

使用注意 | Note

  • 模型有一定概率会出现最后一帧空白的情况,暂不清楚是什么原因,所以目前节点直接删除了最后一帧,所以默认生成结果是15帧
