Can't get video to center on page

I have embedded the following video on this page:

http://www.sonoma.edu/cie/international-students-new/

However, I can't get it to be centered on the page, like the title above it.

I would also like to get rid of some of the padding under the video because it creates a wide space between it and the text below. However, when I try to make the value of the "padding-bottom" smaller, it also causes the video to be narrower.
