There are many different ways to send Vidpresso to air. Depending on the show and the content you may want completely different layouts, luckily, you have a lot of control over where pretty much any element can be placed.
You can find some on-air examples on the homepage in the Examples section
A full screen output is one that will take over the whole broadcast output. It's perfect for putting in monitors, or running full on-air.
##Lower 3rd A lower third can be composited in the switcher, and can look exactly the way you'd think.
##Sidebar Some stations opt to use the sidebar as a background layer, and then have a switcher perform a DVE effect on a 'main video' feed to squeeze back over Vidpresso. Alternatively, you could use a chroma key to perform the same function.
