In our slider gallery view template (Template A) we used a simple header area (Item Title 3) that doesn’t include images or video, since we wanted to show all the content in the slider. However, if you want to, you can use the header with the image and add video to it – you can use any of the other four Item Titles for it. the video in the header area can be from Vimeo or Youtube and the area supports self-hosted video as well.
The slider area will work both with the images and videos. If you want to make a collection of videos in one post, you can use this layout that allows showing a title for each video separately. The slider supports Vimeo or Youtube videos that will open in a popup.
