Embedded vimeo clip showing static image

Hello,

I recently redesigned a lot of my website but am having trouble embedding vimeo videos into my blog:

http://www.blog.leeburnett.co.uk/

The video is appearing full width, but I cannot click anything on the video (it’s as if it appears as a static image, but the buttons are still dynamically moving if it is resized).

I adapted the Manifest theme to suit the rest of my website better, and attempted to make it responsive. I’m very new to responsive coding so don’t know if I’m getting it right or not. I think it’s this that is causing the issue but don’t know where.

Thanks for any help
