Hi Xueqing12,
I haven't tried this VAE you mentioned, so I can't say if it works well.
To create the VAE in ComfyUI, I loaded the original LTX model into a simple checkpoint node and then added a save VAE node right after it.
This process saves the VAE in your ComfyUI folder.
The VAE file is around 799MB, and it works well for me.

The save VAE node @Evados describes is probably the easiest, but the original one you link to above should work as well.

Should I upload a copy of the 800MB version of the VAE to this repo for convenience?

I tried the version provided in the link, and it gives a vae_dtype error with LTXVImgToVideo node.

this is a joke.. no vae

I uploaded a BF16 direct conversion to the root folder here, hopefully that works I just loaded & resaved it via safetensors.torch manually.

With the default comfy nodes I can use the full one as well so I assume you were trying it on the Lightricks nodepack?
