White space above and below video on mobile

I’m having trouble figuring out how to get rid of the white space above and below the video on this page - any help to fx it would be much appreciated. Thank you!

EDIT - I’ve just noticed that in the preview in the designer, it looks OK for all breakpoints, but in the read only preview, it is showing white gaps in most screen sizes the white space gets bigger as you go down to smaller screens). I’m sure it must be something simple, but I’ve lost track of all the different permutation now…
