Hello,
We have confirmed from the Test Site, there is a Video Player element available under the WPBakery page builder plugin which you can use on your Site to add Video: https://snipboard.io/1TCUxg.jpg
This element also has the option to add Poster to Video under the Advanced tab of this element: https://snipboard.io/dnvPFL.jpg
So, you can try to use this element on your Site too if you want.
Regarding the other element, right now we can’t seem to find any sort of element like that under the WPBakery. You can further contact their Support in this regard, if they currently have any sort of element available like that, they can guide you better. Hope you can understand !
Best Regards
