Video output cuts the screen in half. Same applies to view in browser. Why?

I’m relatively new to Hype. I’ve created a very simple animation of 11 slides which looks fine on screen, but when I export it in Movie format,

it cuts off edges and only gives me part of the graphic. Same applies when viewing in browser. What am I doing wrong?

Can you share your .hype document so we can see what might be going wrong? Are you doing any scaling or flexible layout settings in this doc?

Ironically I had the 50% scale button on. Having turned this off, all seems to be working ok.

Thank you anyway for the prompt reply. I have no doubt I’ll be back.
