Background Video Quirk

Hi All! I’m having issues with the editor displaying the background video still. The video publishes to the website and appears in the preview, but not in the editor. I’ve narrowed it down to it being an issue with the video file itself, because some files work, but others do not. I’ve adjusted the FPS, resolution, file size and nothing seems to make a difference. Any ideas?
