2-second continuous video view buying is an optimisation and billing option for video ad buying through the Video Views objective. This optimisation can be used with auction or reach and frequency campaigns. It's currently available for video ads at least three seconds in length.

2-second continuous video view buying ensures that your video ads get the most video plays of two continuous seconds or more. Most 2-second continuous video views will have at least 50% of the video pixels on screen, though in some cases, such as when part of the screen is obscured by a system or app overlay (due to user behaviour such as sharing, saving or receiving a notification), less than 50% of a video's pixels may be in view.
