The terms VAST and VPAID describe two types of programmatic videos. Watch this video to find out the difference between VAST vs. VPAID so you’re in the know when building out your video ad strategy.

Here’s the definitions of VAST and VPAID per the International Advertising Board (IAB):

  • Video Ad-Serving Template (VAST) — common video ad tag language to serve ads on video players
  • Video Player-Ad Interface Definition (VPAID) —  enables interactivity between the publishers ad server and the video player, preloads an ad unit before rendering it and sends ad interaction information such as time watched and playbacks to advertisers and publishers.

So what does this really mean?

One delivers a creative to the player – that’s VAST only. The other, VPAID.js, delivers multiple advertisers to your player and then conducts an auction to deliver the advertisement. VPAID.js adds latency because of the auction process. At sovrn, we want to monetize the most revenue so we deliver both VAST and VPAID ads in one tag or can isolate the tag to VAST only to decrease latency.
