Out Stream Video Ads
Out-stream ads are videos that aren't accompanied by any other content. While roll and interactive content requires something to wrap around - such as a different video or a blog post - an out-stream ad doesn’t need to be tied to anything else.
Interactive Video Ad
Interactive ads can show up before, during, or after the content has played, and usually last for around thirty seconds at most. Although some people enjoy the ability to interact with a brand, many would prefer interactive video ads to take place before, or after the primary content they are watching.
In-Text Video Ads
Ads displayed from underlined words or phrases within textual web content. The ads are triggered by users and are displayed only when a user decides to move his mouse over a relevant word or phrase.
