Problem Embedding H5P Content into Moodle

Hi, 

I have recently been attempting to embed H5P content which I made on H5p.com and downloaded. There are no issues when uploading and inserting the content, however the display seems to be wrong, and I'm not sure how to fix this (see attached pic). The video doesn't display at full size, and is squished. I am attempting to embed on a lesson content page.

Would be grateful if anyone could help !
