Background video filesize doubled by Webflow V2

Sometimes webflow re-encodes my background videos creating a file size much larger than the original. Is this a bug?

I see this older related post https://discourse.webflow.com/t/issue-with-background-video-doubling-in-file-size-when-uploaded-to-webflow - but I can’t understand why the webflow people have not responded as this seems like a resource-guzzling issue… think about all the extra energy used to download these extra bytes… fixing this could save alot of trees.
