Missing EmptyHunyuanLatentVideo Node
I experienced the same issue. I couldn't find anything through web searches.
Same, any clues?
The issue is likely due to an outdated version of your ComfyUI.
I encountered the same problem.
I believed I had updated to the latest version using the "Update ComfyUI" function within ComfyUI Manager, but it appears this was not effective.
If you are using the portable version, I recommend attempting an update to the most recent version by running the bat file located in the "update" folder.
This method resolved the issue for me.

I updated the software with this operation and it succeeded without any errors. (Incidentally, when I ran it, generation failed just before completion after about 8 hours, which takes a long time even on an Nvidia 3090 32GB environment.)
