Inserting slate

Focus mode
Inserting slate - AWS Elemental MediaTailor
Note

Slate is only available for live workflows.

With AWS Elemental MediaTailor, you can designate a slate ad for ad breaks. A slate is a default MP4 asset that is inserted into a stream, such as a still image or looped video, that plays instead of the live content.

AWS Elemental MediaTailor shows a slate in the following situations:

  • To fill in time that's not fully used by an ad replacement

  • If the ad decision server (ADS) responds with a empty VAST or VMAP response

  • For error conditions, such as ADS timeout

  • If the duration of ads is longer than the ad break

  • If an ad isn't available

If you don't configure a slate, MediaTailor defaults to the underlying content stream when one of the above conditions is met.

Configuring the slate

You designate the slate in the additional configuration pane in the MediaTailor console. MediaTailor downloads the slate from the URL that you specify, and transcodes it to the same renditions as your content. You can control the maximum amount of time that a slate will be shown through the optional personalization threshold configuration in the MediaTailor console. For more information, see Optional configuration settings.

Slate configuration and VPAID

You must configure a slate if you're using VPAID ads. To hold space for VPAID ads that the video player inserts, MediaTailor inserts the slate for the duration of the VPAID ad. This duration might be slightly longer than the duration of the VPAID ad as reported by VAST to accommodate user interactivity, as described in VPAID requirements. The video player then handles the VPAID ad based on the client-side reporting metadata that MediaTailor returns. For information about client-side reporting, see Client-side ad tracking.
