Black line above vimeo video + autoplay not working

Hi everyone,

I am having issues with correctly styling my Vimeo video:

I get a black bar (1pixel wide) along the top of my video. I have tried hacking it away by cropping it with a DIV, but I cant get the DIV to stay the same aspect ratio across screen sizes, so its visible on IPad and bellow…

Also I cant get it to autoplay. This is my video url:



Any help would be greatly appreciated!
