I created it using the rendered .png frame outputs, processed by img2webp, which is how I’ve made .webp files before and uploaded them here, quite recently.
I’ve just dowloaded the file from the dropbox link given and then edited my post to remove the orginal image file and upload that downloaded one.
It shows a .webp extension that is rapidly changed to a .jpeg extension.
I’ll try doing it with a different browser…
Tried with Chromium instead of Palemoon - same result.
The file does play as an animated .webp in a browser.
I think it’s a file size thing - it’s 2.1MB so is this above a limit (which I thought was 3MB)?
I disabled a image optimisation setting now. And I also compressed the image to 1.1mb. Can you try it now? Also check both lossless and compressed image. Keep the file name different.
