Video overlay text is a great feature in the advanced panel of the Vieworks platform. What it essentially means is that you can edit the header of your widget seen below which is "Watch this video, earn a perk".
You have a 30 character allowance to play around with, it can even include your brand name "Watch this and win with X brand".
When the user click on pause or tries to skip the video, the video overlay header text will also be seen below and again, replace the "Watch the video, earn a perk"
