Create a new Video Outstream Ad Unit associated with a Prebid Server configuration ID and a video size.

Video Insterstital is only supported with Google Ad Manager.

VideoInterstitialAdUnit(configId: String)


configId(String): Prebid Server configuration ID.


Parameters is a sub class of VideoInterstitialAdUnit.Create new Parameters class to define the parameters of the video ad unit. Parameters contain the OpenRTB video attributes.


placement: [int] or [enum]: OpenRTB placement

api: [int] or [enum]: OpenRTB api frameworks

maxBitrate: int: OpenRTB maxBirate

minBitrate: int: OpenRTB minBitrate

maxDuration:int: OpenRTB maxDuration

minDuration: int: OpenRTB minDuration

mimes: [string]: OpenRTB mime types

playbackMethod: [int]: OpenRTB playbackMethod

protocols: [int] or [enum]: OpenRTB Protocols


OpenRTB 2.5 Placement Type for the auction can be expressed as an integer array or can use an enum for easier readability. Option 1 (in-stream) is intentionally left out due to lack of in-stream support in Prebid SDK.

In the context of a VideoInterstitialAdUnit, rewarded video ads are typically labled as interstitial. As such, Prebid SDK will default to value 5 if no placement value is supplied.

  • 2 or InBanner : In-Banner placement exists within a web banner that leverages the banner space to deliver a video experience as opposed to another static or rich media format. The format relies on the existence of display ad inventory on the page for its delivery.
  • 3 or InArticle : In-Article placement loads and plays dynamically between paragraphs of editorial content; existing as a standalone branded message.
  • 4 or InFeed : In-Feed placement is found in content, social, or product feeds.
  • 5 or Slider, Floating or Interstitial : Open RTB supports one of three values for option 5 as eitehr Slider, Floating or Interstitial. If an enum value is supplied in placement, bidders will recieve value 5 for placement type and assume to be interstitial with the instl flag set to 1.
