Video zooms in?

Why is when I start a video it zooms in my camera focus? The screenshots below are from the same camera angle, the only difference being one is in video mode and you can see it crops the edges a little when it zoomed in.

There are a couple of threads already running about this, turn of Video stabilisation and set the aspect ratio at 16:9.
