Microsoft Invest - Companions

A companion is a creative that is commonly displayed in the form of a standard banner or rich media. It can also wrap the video ad experience. Companions are supported on VAST version 2.0 and higher.

Companions are typically served with linear or non-linear creatives. The following rendering modes can be used to indicate when and where the companion should display:

Rendering Mode Description
End-Card The companion is rendered after the video playback has stopped. The companion's dimensions should match the dimensions of the video or audio creative.
Concurrent The companion is rendered alongside the video or audio creative for the entire duration of the video playback.
Default Depending upon the player's default behavior, the companion will either be rendered after the video playback has stopped (end-card) or alongside the video or audio creative for the entire duration of the video playback (concurrent).

Note

Rendering modes are only supported on VAST versions 4.1 and 4.2.
