outstream video

a.k.a. inread, in-read, native video
A video ad unit that appears within text when the user is scrolling. The format does not require a video player and is easy to implement.

This type of online ad autoplays in a large format player whenever a user navigates to it within text content (such as an article) even if the website publisher doesn't have their own video content.
