Why does embedded video automatically move down within the container?

Hi, I’m using a Vimeo Embed code, but I’m having the same experience with other video embeds as well. When I drop the video module into the container and then add the embed video code the video appears but it is alway appears at the bottom of the container. Why is the default to not be at the top of the container? Where is all of this padding coming from? I can add a negative number to the top margin of the container, but this is not a very functional solution because it moves the boundary of the container off the page.
