In-stream video creatives are played in video players on web pages. They are played before, in the middle of, or after other video content, and use VAST XML to ensure proper rendering in the players.
Out-stream video ads are those that are embedded within the body of an article, mostly set to auto-play when the reader reaches the part of the page that contains the ad. The sound is usually not activated unless the reader hovers over the ads with their mouse.
In-banner video creatives are played in banner placements rather than in video players. The ad buyer must serve the video player code and the VAST video creative together.
VAST stands for Video Ad Serving Template. It is an XML-based video ad serving protocol that provides a uniform way for video content to be transferred from ad servers to video players on web pages. VAST allows for linear video creatives to be served without interactivity. VPAID modules can be included within a VAST document to facilitate interactivity.
Pure linear VAST (without VPAID modules) do not allow the buyer to measure viewability, but do allow the measurement of starts, quartile completions, and completed views. Pure linear VAST is common in mobile video. For more details about VAST, see the Interactive Advertising Bureau's VAST documentation at IAB Guidelines for VAST.

Video Multiple Ad Playlist (VMAP) is a form of “ad podding.” It allows sellers to create commercial breaks, similar to linear broadcast TV, and is mostly used in long-form content. VMAP is designed to produce rules around which types of ads can be played together and how they interact with one another. For example, VMAP can be configured to prevent ads from competitors (e.g. BMW and Audi) from playing directly next to one another.
