WebM background video alpha/transparency not working?

I have created a WebM video with a transparent background that I am using as a background video. Unfortunately the alpha channel doesn’t appear to be working when I publish and view in Chrome. The transparent area just shows as black:

Is there a way to enable the WebM format alpha channel for the background video component in Webflow?

Thanks for posting about this — it definitely sounds like odd behavior.

What sites are you seeing this issue occur in – only this project or multiple projects? When did it start occurring? Can you send me the site Read-Only links please?

Could you also please let me know what browser version you’re using by sending me your information from this page?

There should be a small share link when you visit the page which you can send to me.

Thanks in advance!

This is my first project using WebM video so this is the first time I have noticed it.

Here is a simple example showing the issue:

Notice the black background on the video… that should be transparent. I encoded the video with the alpha channel so I would assume the black area should actually be showing the red background.
