How to reposition background video within it's container

I’ve been beating my head all over the tutorials, walk-throughs, and forums… but I can’t find a solution.

I’m reconstructing a website and there are two videos used with specific cropping for focus on the eyes of the person in each video. When I transferred the videos to background videos in Webflow, it is choosing how to center the video… and it is all wrong.

I cannot figure out how to change the positioning of the video to crop the video within the container the way I would like. This is especially important with the scaling that happens across the mobile devices. I want to maintain the same crop/aspect ratio with each version/break point.

How can I accomplish this?

Thank you for any/all help.
