Player Card - Preview displayed only after "View Media" is clicked


Hey guys,
I’ve been creating a webpage which contains meta tags in order to display a video on Twitter but I’ve got a question regarding this issue -
when viewing my post on the feed, the video preview box is only displayed after clicking the “View Media” link. For videos of Vine, for example, it’s opened right away.
If I start an ads campaign with the same post, will the preview be displayed without need to click the “View Media” ?

I’d like to know how to make the preview display without the need to click on this link, please tell me if i’m doing something wrong ! I’d really like to know how to overcome this obstacle, thanks in advance !
