That's a video. To post a video, you need a video tag. If the typing instructions I provided is too complicated, use the icons above the area you enter your text. Since it is a video, go to the fifth icon, which says, "enter a media tag." Select the source of the video, in this case, YouTube. Enter the link into the box which came up and click "OK."
