Can't keep video height at 100% relative to viewport, portrait or landscape, all times

Hey guys!

I'm having a hard time getting around this responsive design issue. Maybe you can help me.

I have a landscape, fullscreen, embeded video on stage.

I need it to always be horizontally centered on any screen, and at 100% height.

Which means, in landscape, it will basically display the whole video.

However, in portrait, it should cut off the sides, keeping only what fits in the middle, when the height is at 100%.

I tried all the settings I could think of using the breakpoint views. Nothing worked.

Any ideias?
