When we upload MP4 video into the Media library and insert into the page, there is extra space on the right side, which we are unable to edit, align or format.

How to make the alignment proper.
Thanks for reporting this. We centre embedded media from external sources (in <iframes> — see https://github.com/pressbooks/buckram/pull/158) but we didn’t add corresponding styles to centre embedded video from the media library. I’ve addressed this in https://github.com/pressbooks/buckram/pull/257.
