Not working in drupal 8 with "video" module and a view

Hi all!,

I´ve done a view with grid because i want to do a Gallery. Then i used the "video" module to create a content field called video.

I put 2 videos in the view, but the videos aren't responsive. You can see the webpage in the following direction:

http://www.pescaomuere.com/videos

In the other way, if i go to the content, not using the view, i can see the video responsive working right the fitvids module. It's a pity and i don't know what is happening, but i need the gallery so i need the view.

Using embebed video player or HTML5 video player in the field "video" in my view has the same effects. Not working the responsive way.

Thanks!

Edit:

I think it is because of the grid system of the view. This is what is not responsive, and the videos couple next to another.
