Double Exposure Background Video?

Hello community,
I saw a great landing page on Instagram (Image attached) and I was wondering if and how it’s possible to re-create this design with webflow. (custom code for sure but how exactly?) I would like to have a black background with a shape as cutout so you can see a background video behind the shape.

Thanks in advance.

Honestly, I’d make the image on the right in photoshop and put text to the left. No need to try to do it with CSS.
