`SaveAnimatedWEBP` node doesn't save metadata about comfyui

yes you should try removing that web/extensions/webpinfo/webpinfo.js file, it shouldn't break anything.

SaveAnimatedWEBP does save the metadata in the WebP file.

If you try loading the files on here does it work? https://comfyanonymous.github.io/ComfyUI_examples/video/

Can you upload one of your WebP files?

does it work? https://comfyanonymous.github.io/ComfyUI_examples/video/

No, none of the two files loads workspace. Neither by dragging-and-dropping the file onto browser, nor by choosing it with the Load button.

Here are my files:
testWEBP.zip

1. BuiltInPNG_00001_.png - saved with the default Save Image node.
2. BuiltInWEBP_00001_.webp - saved with SaveAnimatedWEBP node.
3. CustomNodeWEBP_00001_.webp saved with this custom node.

Files 1 and 3 both load their workspace with no issue. Even when ComfyUI launched with --disable-all-custom-nodes flag.
File 2 doesn't load anything - whether I start ComfyUI with or without this flag. 🤷🏻‍♂️

All 3 work load fine here, can you try on a clean ComfyUI to see if you still can't load it?

That would take quite some time, since I have a complicated setup (all the models are stored outside ComfyUI and symlinked by each folder, individually).
But yeah. Give me about an hour to get to my desktop PC and try it.

Hmmm... You were right. On a clean ComfyUI install, all 3 files load their workspace.

I'm no web-programmer, but by comparing my old and clean ComfyUI installs, I've found that the old one has an extra file under web/extensions/webpinfo/webpinfo.js. I'm guessing, this file was added by the aforementioned custom node and it overrides some webp-related behavior.
And since it's outside custom_nodes folder, it still might've been doing what it does, even when ComfyUI was launched with --disable-all-custom-nodes.
webpinfo.zip

So the solution would be removing that custom node, AS WELL AS this file, wouldn't it?
Removing webpinfo.js shouldn't break my main ComfyUI installation in any other way, should it?

I'd like to avoid setting it up from scratch, with all the custom nodes I have installed.
