I've run into this issue as well...

Assuming you've already used ComfyUI Manager to "Install Missing Custom Nodes," and are running latest Comfy, and this node still appears missing, then try loading the workflow json file using the "Load" button on comfy control panel.

I don't know why, but drag-and-dropping sometimes makes this node appear missing... Manually loading the json seems to fix the issue for me.

After manually loading the json, then I can drag and drop my previous generations and it works fine.

If that doesn't work, then I'm not sure! 🤷‍♂️ Maybe someone else has figured out this issue? I just updated to latest Comfy and have been fighting this and other issues all week 💢

@makeenrondo264 I actually switched workflows because of this and other issues.

I wound up using/modifying this example from Replicate's github:

https://github.com/replicate/cog-comfyui-wan-with-lora/blob/main/workflows/wan-with-lora-i2v-ui.json

Uses more native nodes. Also it's an easier workflow for my simple brain to follow.

The default sampler settings are different- I used Euler A, 6.0 cfg, 20 steps. Also the default video length in this workflow is 32 (33) frames (2 seconds) so you probably want to increase that.

Note this also includes TeaCache node which you can bypass/delete if you're not familiar with it yet or if it doesn't work. But it's worth trying, good speed increase.
