How do you create scroll-stopping video ads?

I came across a Facebook video ad run by Promo and fascinated by that I signed up on their platform and looked for the template to make such video, but there wasn't any! Later, in a comment on their Facebook page, I discovered they were running that video ad to grab users' attention and they do no offer such template. So, any marketers, video editors, graphics designers know any platform to make video ads that like that? Edit: Okay, as it seems description field doesn't support hyperlinks, the link is in the comment below!
