Need help sizing background videos to be responsive

Referencing my first project:

I’m designing my portfolio site and struggling back and forth with keeping it responsive. I’ve been going through and steadily tidying it up, but it’s my first time and still quite messy. Been at it 2 weeks.

I have background videos to display how the product I designed will interact, just to show off the animation a bit and earn points. But I can’t size it right and sometimes its too big or too small. It’s probably going to be a simple solution, but I’d appreciate the help.

Cheers
