Hi all - in the Authoring Tool - media component - my mp4 video is 800 x 600, but when the page loads it sits paused at 900px x 506px and then when i hit play it zooms up to 900 x 675px.

Also I have made an asset to put in as the Poster Link which is the same size as the video and it is showing as a lot smaller than the video screen when it shows - as below. Any advice?
