Hi. Good questions. Unfortunately, X3 has limited video support. We can't add videos mixed in with images, because videos don't have thumbnails, can't integrate properly in "advanced" gallery layouts, and they don't exhibit the same "click" behavior. (In a future release, I would have like add better video support, although there are some challenges).
Therefore, for now, we have to add videos separately, either above or below the actual gallery.

Secondly, is there any way to get them not to appear as full screen? The vertical videos currently don't fit on the screen well on desktop.
Indeed. Please try to add something like this to your Settings > Custom > Custom CSS:
.x3-video-container {
max-width: 800px; /* feel free to adjust this value */
margin: auto;
}
The reason the videos are 100% wide in the first place, is because they inherit the width of your gallery, which is set to 100%. I agree it makes sense to limit the width of videos so they don't occupy the entire stage (or more).
