Responsive Video Background

How can I make my animated photo be responsive to mobile? I’ve tried adjusting some settings and even changed the resolution of the animated photo, but it didn’t work. If you have time to check my issue, it’s the animated photo with the rocket ship.
I am new to webflow so I really appreicate any help. Thank you!
