Background Video Needs to Resize from Bottom Right Corner

So I have a bg video for the landing, and when the screen gets smaller I need the bottom right to always be visible and to hide the left side as the window shrinks. Basically, I have the subject of the video on the right side of the composition. When the window shrinks, the video get cut from the center, therefore, on smaller sizes the object is out of the window.

I’m not sure if I’m making sense. I can’t show the website, so I’m building a trash page to showcase what I mean. Read Only link coming soon. Thx
