Video - removing padding and wrapper

Site URL: https://morejuice.squarespace.com/config/

Hi there,

I'm in desperate need of some help from some experienced coders to help me fix a small thing so I can make a website live! 

 I have a video on the home page on the left hand side of the section, I need to remove all padding and white space around it, so it's full bleed when on both display and on mobile. 

And if anyone has a technique for making my mute button turned off so sound automatically plays when you land on the site that would be great!

Any help within the next 24 hours would be amazing!

Many thanks

Caroline
