你好，我使用786X1024的图片作为底图，使用“workflow_FUN_I2V_GGUF_Q4_0.png”这个工作流，生成1024分辨率的视频会爆显存；768分辨率下没问题。 显卡：RTX 4060TI 16GB. OS: Ubuntu22.04 Docker 中运行 vae encode tiling 已经打开

是不是因为我的底图太大了？

[wailovet]

有没有报错信息 我想知道在哪一段代码爆的显存

[wailovet]

不过我自己跑的话,很极限,1024占用会在99%, 你可以尝试减少一下视频帧长度

这是报错信息：

vae encode时的报错,是不是本来跑的时候显存就已经占用了一些了, 我和你一样16G显存,开启vae encode tiling以后将将能用

请问下你是在Linux下使用的吗？我是在win11下使用wsl2 启动的linux子系统，并且通过docker跑的服务，会不会有影响。

[wailovet]

是的,我是直接本机的linux,跑的时候显存占用顶到99%

我装了一个ubuntu22.04，把环境都搞了一遍，960 分辨率都跑不出来，可能是我的原始图片分辨率太高了
