One of the box types enables you to include embedded video. To get the video to display at an appropriate size, you'll want to make the column in which it appears large enough for the entire video to display. With the library's streaming videos, set a 2-column display with the video column set at 758 and the other column at 209. An example appears in a box lower on this page. Boxes to copy for including the library's streaming videos are available on the General Resources guide.
