Yes, you can still access Vimeo hosted MP4 files for higher end paid accounts (not free, and not Plus).

I am also waiting this feature at least from GP premium. Actually with page builder Elementor you can put a Youtube link for videobackground in a section and push it to Header... I don't know why but i want to use GP header :) Is there any news about this coming feature??

I haven't found a consistent way of doing this yet - I'll see if there's anything I can learn from Elementor when it comes to this :)
