review my custom liquid code for video play including unmute

[lepuffcases]

Hi there,

I have a liquid code and it's not perfect. For both desktop and mobile the video is to wide so my question is if somebody can help me with my liquid code so that I can adjust a different video for desktop and mobile. And have the mute/ unmute button in the screen field
