There are 2 choices here for rendering, but you can add more, or tweak the ones that are already up.
The demo is limited to 800x600 and a quality of 1. Careful as the default, even for "Full Render" is much lower than this.
One other thing to note here - The button highlighted at the lower right - "Copy this view to Current Render Camera" if you move the view at all - DO NOT FORGET to click this.
