Video player size on pages

I am using the Sydney theme. The page attributes template box options are default or full page, (or front page which I don’t want.) Each of them sizes the vimeo player for me to a default size no mater what size I enter manually in the code – (eg – width=”1000″ height=”562″

I have used many other themes, (mostly Elegant themes) and never had this problem. I would like to know how to control the size of the video player on my pages.
Thank you
