VMAP (Video Multiple Ad Playlist)

VMAP allows content owners to describe the structure for ad-inventory insertion when they do not control the video player themselves — as is the case on platforms like YouTube, where creators upload content but have no influence over the player environment.

Designed to work in conjunction with VAST (Video Ad-Serving Template), VMAP is well-suited for video content creators who lack control over the player but still want to define the ad experience within their videos — specifying, for example, where pre-roll, mid-roll, or post-roll ads should appear.
