Can Unreal Engine AR/UE in general be used to make effects in post?

I want to record a video and add in 3d elements in post editing, is there a way to do it?

I cant seem to find anything but I remember seeing that thing about how they used unreal engine to show natural disasters which is pretty much what I want to do
(news thing i talked about: This terrifying graphic from The Weather Channel shows the power and danger of Hurricane Florence - The Verge )
