How can I resize a video for desktop viewing?

[valerie92]

Can someone help me resize my video for desktop. On mobile it looks perfect but once you view in a desktop it's huge and takes up the whole screen. I'm not sure how to resize and make it smaller on a desktop. 

If anyone can help! Thank you.
