Video cropping

Why does the site crop the video so I can't see the right edge past the image? I can't see the number of the video length or the control to toggle between full screen. I'd like to be able to view them in full screen.

If it is a Youtube video you can right click (long press on a mobile device) and copy the url.  Put in the browser search bar and it will open in youtube where it can be played full screen.

I'm viewing on an iPad. The long click thing doesn't work on it. Maybe I can find another way to make that work. Thanks.
